• What is Database Continuous Integration?

  - by David Atkinson

  Although not everyone is practicing continuous integration, many have at least heard of the concept. A recent poll on www.simple-talk.com indicates that 40% of respondents are employing the technique. It is widely accepted that the earlier issues are identified in the development process, the lower the cost to the development process. The worst case scenario, of course, is for the bug to be found by the customer following the product release. A number of Agile development best practices have evolved to combat this problem early in the development process, including pair programming, code inspections and unit testing. Continuous integration is one such Agile concept that tackles the problem at the point of committing a change to source control. This can alternatively be run on a regular schedule. This triggers a sequence of events that compiles the code and performs a variety of tests. Often the continuous integration process is regarded as a build validation test, and if issues were to be identified at this stage, the testers would simply not 'waste their time ' and touch the build at all. Such a ‘broken build’ will trigger an alert and the development team’s number one priority should be to resolve the issue. How application code is compiled and tested as part of continuous integration is well understood. However, this isn’t so clear for databases. Indeed, before I cover the mechanics of implementation, we need to decide what we mean by database continuous integration. For me, database continuous integration can be implemented as one or more of the following: 1)      Your application code is being compiled and tested. You therefore need a database to be maintained at the corresponding version. 2)      Just as a valid application should compile, so should the database. It should therefore be possible to build a new database from scratch. 3)     Likewise, it should be possible to generate an upgrade script to take your already deployed databases to the latest version. I will be covering these in further detail in future blogs. In the meantime, more information can be found in the whitepaper linked off www.red-gate.com/ci If you have any questions, feel free to contact me directly or post a comment to this blog post.

• Database Mirroring – deprecated

  - by fatherjack

  Do you use mirroring on any of your databases? Do you use mirroring on SQL Server Standard Edition? I do, as a way of having a stand-by server ready to take over if there is a problem with the live server so that business can continue despite whatever disaster may strike at our primary server location. In my experience it has been a great solution for us as it is simple to implement, reliable and predictable. Mirroring has been around since SQL Server 2005 sp1 but with the release of SQL Server 2012 mirroring has now been placed on the deprecation list. That’s right, Microsoft are removing this feature from SQL Server. SQL Server 2012 had lots of improvements and new features around this sort of technology – the High Availability, Disaster recovery and Always On features described in detail here by Brent Ozar and  Microsoft’s own Customer Service and Support SQL Server Engineers . Now the bad news, the HADRON features are pretty much all wrapped up in the Enterprise Edition of SQL Server 2012. This is going to be a big issue for people, like me, who are only on Standard Edition of earlier versions mostly due to our requirements and the budget (or lack thereof) required for Enterprise Edition licenses. No mirroring in Standard Edition means no upgrade. Don’t Panic. There are two stages of deprecation and they dont happen fast. The first stage – Deprecation Announcement- means that Microsoft have decided that there is a limited future for a particular feature and this is your cue that new projects and developments should not be implemented on this technology as it will cease to exist in the future. This is where mirroring currently stands. You have time to consider your options and start work on planning how you will move away from using this feature. This can be 2 or 3 versions of SQL Server, possibly more. The next stage is Deprecation Final Support - this is where you are on your last chance, When you see this then the next version of SQL Server will not have this feature in it so you need to implement your plans to move to an alternative solution. While these two phases are taking place Microsoft are open to feedback on how people use their products and if enough people make the case for mirroring (or an equivalent technology) to be in the Standard Edition then they may make changes rather than lose customers or have customers cease upgrading in order to keep the functionality they need. Denny Cherry (@MrDenny) has published an article on this same topic here with more detail than me so I wont go over old ground. All I will say is that you should read his article now and then follow the link to his own site where he is collecting peoples information on how they use mirroring in Standard Edition so that our voice can be put to Microsoft.

• Interviews: Going Beyond the Technical Quiz

  - by Tony Davis

  All developers will be familiar with the basic format of a technical interview. After a bout of CV-trawling to gauge basic experience, strengths and weaknesses, the interview turns technical. The whiteboard takes center stage and the challenge is set to design a function or query, or solve what on the face of it might seem a disarmingly simple programming puzzle. Most developers will have experienced those few panic-stricken moments, when one’s mind goes as blank as the whiteboard, before un-popping the marker pen, and hopefully one’s mental functions, to work through the problem. It is a way to probe the candidate’s knowledge of basic programming structures and techniques and to challenge their critical thinking. However, these challenges or puzzles, often devised by some of the smartest brains in the development team, have a tendency to become unnecessarily ‘tricksy’. They often seem somewhat academic in nature. While the candidate straight out of IT school might breeze through the construction of a Markov chain, a candidate with bags of practical experience but less in the way of formal training could become nonplussed. Also, a whiteboard and a marker pen make up only a very small part of the toolkit that a programmer will use in everyday work. I remember vividly my first job interview, for a position as technical editor. It went well, but after the usual CV grilling and technical questions, I was only halfway there. Later, they sat me alongside a team of editors, in front of a computer loaded with MS Word and copy of SQL Server Query Analyzer, and my task was to edit a real chapter for a real SQL Server book that they planned to publish, including validating and testing all the code. It was a tough challenge but I came away with a sound knowledge of the sort of work I’d do, and its context. It makes perfect sense, yet my impression is that many organizations don’t do this. Indeed, it is only relatively recently that Red Gate started to move over to this model for developer interviews. Now, instead of, or perhaps in addition to, the whiteboard challenges, the candidate can expect to sit with their prospective team, in front of Visual Studio, loaded with all the useful tools in the developer’s kit (ReSharper and so on) and asked to, for example, analyze and improve a real piece of software. The same principles should apply when interviewing for a database positon. In addition to the usual questions challenging the candidate’s knowledge of such things as b-trees, object permissions, database recovery models, and so on, sit the candidate down with the other database developers or DBAs. Arm them with a copy of Management Studio, and a few other tools, then challenge them to discover the flaws in a stored procedure, and improve its performance. Or present them with a corrupt database and ask them to get the database back online, and discover the cause of the corruption.

• Developing Schema Compare for Oracle (Part 3): Ghost Objects

  - by Simon Cooper

  In the previous blog post, I covered how we solved the problem of dependencies between objects and between schemas. However, that isn’t the end of the issue. The dependencies algorithm I described works when you’re querying live databases and you can get dependencies for a particular schema direct from the server, and that’s all well and good. To throw a (rather large) spanner in the works, Schema Compare also has the concept of a snapshot, which is a read-only compressed XML representation of a selection of schemas that can be compared in the same way as a live database. This can be useful for keeping historical records or a baseline of a database schema, or comparing a schema on a computer that doesn’t have direct access to the database. So, how do snapshots interact with dependencies? Inter-database dependencies don't pose an issue as we store the dependencies in the snapshot. However, comparing a snapshot to a live database with cross-schema dependencies does cause a problem; what if the live database has a dependency to an object that does not exist in the snapshot? Take a basic example schema, where you’re only populating SchemaA: SOURCE   TARGET (using snapshot) CREATE TABLE SchemaA.Table1 ( Col1 NUMBER REFERENCES SchemaB.Table1(col1));   CREATE TABLE SchemaA.Table1 ( Col1 VARCHAR2(100)); CREATE TABLE SchemaB.Table1 ( Col1 NUMBER PRIMARY KEY);   CREATE TABLE SchemaB.Table1 ( Col1 VARCHAR2(100)); In this case, we want to generate a sync script to synchronize SchemaA.Table1 on the database represented by the snapshot. When taking a snapshot, database dependencies are followed, but because you’re not comparing it to anything at the time, the comparison dependencies algorithm described in my last post cannot be used. So, as you only take a snapshot of SchemaA on the target database, SchemaB.Table1 will not be in the snapshot. If this snapshot is then used to compare against the above source schema, SchemaB.Table1 will be included in the source, but the object will not be found in the target snapshot. This is the same problem that was solved with comparison dependencies, but here we cannot use the comparison dependencies algorithm as the snapshot has not got any information on SchemaB! We've now hit quite a big problem - we’re trying to include SchemaB.Table1 in the target, but we simply do not know the status of this object on the database the snapshot was taken from; whether it exists in the database at all, whether it’s the same as the target, whether it’s different... What can we do about this sorry state of affairs? Well, not a lot, it would seem. We can’t query the original database, as it may not be accessible, and we cannot assume any default state as it could be wrong and break the script (and we currently do not have a roll-back mechanism for failed synchronizes). The only way to fix this properly is for the user to go right back to the start and re-create the snapshot, explicitly including the schemas of these 'ghost' objects. So, the only thing we can do is flag up dependent ghost objects in the UI, and ask the user what we should do with it – assume it doesn’t exist, assume it’s the same as the target, or specify a definition for it. Unfortunately, such functionality didn’t make the cut for v1 of Schema Compare (as this is very much an edge case for a non-critical piece of functionality), so we simply flag the ghost objects up in the sync wizard as unsyncable, and let the user sort out what’s going on and edit the sync script as appropriate. There are some things that we do do to alleviate somewhat this rather unhappy situation; if a user creates a snapshot from the source or target of a database comparison, we include all the objects registered from the database, not just the ones in the schemas originally selected for comparison. This includes any extra dependent objects registered through the comparison dependencies algorithm. If the user then compares the resulting snapshot against the same database they were comparing against when it was created, the extra dependencies will be included in the snapshot as required and everything will be good. Fortunately, this problem will come up quite rarely, and only when the user uses snapshots and tries to sync objects with unknown cross-schema dependencies. However, the solution is not an easy one, and lead to some difficult architecture and design decisions within the product. And all this pain follows from the simple decision to allow schema pre-filtering! Next: why adding a column to a table isn't as easy as you would think...

• Subterranean IL: Fault exception handlers

  - by Simon Cooper

  Fault event handlers are one of the two handler types that aren't available in C#. It behaves exactly like a finally, except it is only run if control flow exits the block due to an exception being thrown. As an example, take the following method: .method public static void FaultExample(bool throwException) { .try { ldstr "Entering try block" call void [mscorlib]System.Console::WriteLine(string) ldarg.0 brfalse.s NormalReturn ThrowException: ldstr "Throwing exception" call void [mscorlib]System.Console::WriteLine(string) newobj void [mscorlib]System.Exception::.ctor() throw NormalReturn: ldstr "Leaving try block" call void [mscorlib]System.Console::WriteLine(string) leave.s Return } fault { ldstr "Fault handler" call void [mscorlib]System.Console::WriteLine(string) endfault } Return: ldstr "Returning from method" call void [mscorlib]System.Console::WriteLine(string) ret } If we pass true to this method the following gets printed: Entering try block Throwing exception Fault handler and the exception gets passed up the call stack. So, the exception gets thrown, the fault handler gets run, and the exception propagates up the stack afterwards in the normal way. If we pass false, we get the following: Entering try block Leaving try block Returning from method Because we are leaving the .try using a leave.s instruction, and not throwing an exception, the fault handler does not get called. Fault handlers and C# So why were these not included in C#? It seems a pretty simple feature; one extra keyword that compiles in exactly the same way, and with the same semantics, as a finally handler. If you think about it, the same behaviour can be replicated using a normal catch block: try { throw new Exception(); } catch { // fault code goes here throw; } The catch block only gets run if an exception is thrown, and the exception gets rethrown and propagates up the call stack afterwards; exactly like a fault block. The only complications that occur is when you want to add a fault handler to a try block with existing catch handlers. Then, you either have to wrap the try in another try: try { try { // ... } catch (DirectoryNotFoundException) { // ... // leave.s as normal... } catch (IOException) { // ... throw; } } catch { // fault logic throw; } or separate out the fault logic into another method and call that from the appropriate handlers: try { // ... } catch (DirectoryNotFoundException ) { // ... } catch (IOException ioe) { // ... HandleFaultLogic(); throw; } catch (Exception e) { HandleFaultLogic(); throw; } To be fair, the number of times that I would have found a fault handler useful is minimal. Still, it's quite annoying knowing such functionality exists, but you're not able to access it from C#. Fortunately, there are some easy workarounds one can use instead. Next time: filter handlers.

• Easy Profiling Point Insertion

  - by Geertjan

  One really excellent feature of NetBeans IDE is its Profiler. What's especially cool is that you can analyze code fragments, that is, you can right-click in a Java file and then choose Profiling | Insert Profiling Point. When you do that, you're able to analyze code fragments, i.e., from one statement to another statement, e.g., how long a particular piece of code takes to execute: https://netbeans.org/kb/docs/java/profiler-profilingpoints.html However, right-clicking a Java file and then going all the way down a longish list of menu items, to find "Profiling", and then "Insert Profiling Point" is a lot less easy than right-clicking in the sidebar (known as the glyphgutter) and then setting a profiling point in exactly the same way as a breakpoint: That's much easier and more intuitive and makes it far more likely that I'll use the Profiler at all. Once profiling points have been set then, as always, another menu item is added for managing the profiling point: To achieve this, I added the following to the "layer.xml" file: <folder name="Editors"> <folder name="AnnotationTypes"> <file name="profiler.xml" url="profiler.xml"/> <folder name="ProfilerActions"> <file name="org-netbeans-modules-profiler-ppoints-ui-InsertProfilingPointAction.shadow"> <attr name="originalFile" stringvalue="Actions/Profile/org-netbeans-modules-profiler-ppoints-ui-InsertProfilingPointAction.instance"/> <attr name="position" intvalue="300"/> </file> </folder> </folder> </folder> Notice that a "profiler.xml" file is referred to in the above, in the same location as where the "layer.xml" file is found. Here is the content: <!DOCTYPE type PUBLIC '-//NetBeans//DTD annotation type 1.1//EN' 'http://www.netbeans.org/dtds/annotation-type-1_1.dtd'> <type name='editor-profiler' description_key='HINT_PROFILER' localizing_bundle='org.netbeans.eppi.Bundle' visible='true' type='line' actions='ProfilerActions' severity='ok' browseable='false'/> Only disadvantage is that this registers the profiling point insertion in the glyphgutter for all file types. But that's true for the debugger too, i.e., there's no MIME type specific glyphgutter, instead, it is shared by all MIME types. Little bit confusing that the profiler point insertion can now, in theory, be set for all MIME types, but that's also true for the debugger, even though it doesn't apply to all MIME types. That probably explains why the profiling point insertion can only be done, officially, from the right-click popup menu of Java files, i.e., the developers wanted to avoid confusion and make it available to Java files only. However, I think that, since I'm already aware that I can't set the Java debugger in an HTML file, I'm also aware that the Java profiler can't be set that way as well. If you find this useful too, you can download and install the NBM from here: http://plugins.netbeans.org/plugin/55002

• Basic web architecture : Perl -> PHP

  - by Sunny Jim

  This is an architecture question. If there is a better forum, please redirect me. Apologies in advance. Essentially every website is built around a relational database, right? When a user uploads form data, that data is stored in a table. The problem is that the table structure(s) need to be modified whenever the website form is modified. Although I understand that modern web frameworks work around this problem by automatically building forms based on the table structure. For the last 20 years, I have been building websites using Perl. When I first encountered this problem, the easiest solution was to save serialized Perl objects as data BLOBS. After XML's introduction, this solution worked even better because XML is so effective for representing arbitrary data. This approach is consistent with the original Perl principles of Hubris, Laziness, and Impatience and I'm pretty committed to it. Obviously, the biggest drawback is that this solution locks me into the Perl interpreter. So instead, I've just completed a prototype of a universal RDB table. The prototype is written in Perl but porting it to PHP will be a good chance to develop those skills. The principal is based on the XML::Dumper module, which converts arbitrary Perl data structures into uniform XML. With my approach, each XML node is stored as a table record. I underestimated this undertaking and rolled something up myself. But the effort allows me to discuss the basic design instead of implementation details. As mentioned, I'm pretty committed to this approach of using flexible data structures. It's been successfully deployed on many websites, large, and complex. But are there any drawbacks I've overlooked? I rolled my own. Are other people taking a similar approach to their data? What kinds of solutions are available? I have not abandoned my dream of eventually contributing something useful to the worldwide community. In order to proceed, the next step would be peer review. How does one pursue that effort? Thanks! -Jim

• Antenna Aligner Part 5: Devil is in the detail

  - by Chris George

  "The first 90% of a project takes 90% of the time and the last 10% takes the another 200%"  (excerpt from onista) Now that I have a working app (more or less), it's time to make it pretty and slick. I can't stress enough how useful it is to get other people using your software, and my simple app is no exception. I handed my iPhone to a couple of my colleagues at Red Gate and asked them to use it and give me feedback. Immediately it became apparent that the delay between the list page being shown and the list being drawn was too long, and everyone who tried the app clicked on the "Recalculate" button before it had finished. Similarly, selecting a transmitter heralded a delay before the compass page appeared with similar consequences. All users expected there to be some sort of feedback/spinny etc. to show them it is actually doing something. In a similar vein although for opposite reasons, clicking the Recalculate button did indeed recalculate the available transmitters and redraw them, but it did this too fast! One or two users commented that they didn't know if it had done anything. All of these issues resulted in similar solutions; implement a waiting spinny. Thankfully, jquery mobile has one built in, primarily used for ajax operations. Not wishing to bore you with the many many iterations I went through trying to get this to work, I'll just give you my solution! (Seriously, I was working on this most evenings for at least a week!) The final solution for the recalculate problem came in the form of the code below. $(document).on("click", ".show-page-loading-msg", function () {            var $this = $(this),                theme = $this.jqmData("theme") ||                        $.mobile.loadingMessageTheme;            $.mobile.showPageLoadingMsg(theme, "recalculating", false);            setTimeout(function ()                           { $.mobile.hidePageLoadingMsg(); }, 2000);            getLocationData();        })        .on("click", ".hide-page-loading-msg", function () {              $.mobile.hidePageLoadingMsg();        }); The spinny is activated by setting the class of a button (for example) to the 'show-page-loading-msg' class. Recalculate This means the code above is fired, calling the showPageLoadingMsg on the document.mobile object. Then, after a 2 second timeout, it calls the hidePageLoadingMsg() function. Supposedly, it should show "recalculating" underneath the spinny, but I've not got that to work. I'm wondering if there is a problem with the jquery mobile implementation. Anyway, it doesn't really matter, it's the principle I'm after, and I now have spinnys!

• Encrypting your SQL Server Passwords in Powershell

  - by laerte

  A couple of months ago, a friend of mine who is now bewitched by the seemingly supernatural abilities of Powershell (+1 for the team) asked me what, initially, appeared to be a trivial question: "Laerte, I do not have the luxury of being able to work with my SQL servers through Windows Authentication, and I need a way to automatically pass my username and password. How would you suggest I do this?" Given that I knew he, like me, was using the SQLPSX modules (an open source project created by Chad Miller; a fantastic library of reusable functions and PowerShell scripts), I merrily replied, "Simply pass the Username and Password in SQLPSX functions". He rather pointed responded: "My friend, I might as well pass: Username-'Me'-password 'NowEverybodyKnowsMyPassword'" As I do have the pleasure of working with Windows Authentication, I had not really thought this situation though yet (and thank goodness I only revealed my temporary ignorance to a friend, and the embarrassment was minimized). After discussing this puzzle with Chad Miller, he showed me some code for saving passwords on SQL Server Tables, which he had demo'd in his Powershell ETL session at Tampa SQL Saturday (and you can download the scripts from here). The solution seemed to be pretty much ready to go, so I showed it to my Authentication-impoverished friend, only to discover that we were only half-way there: "That's almost what I want, but the details need to be stored in my local txt file, together with the names of the servers that I'll actually use the Powershell scripts on. Something like: Server1,UserName,Password Server2,UserName,Password" I thought about it for just a few milliseconds (Ha! Of course I'm not telling you how long it actually took me, I have to do my own marketing, after all) and the solution was finally ready. First , we have to download Library-StringCripto (with many thanks to Steven Hystad), which is composed of two functions: One for encryption and other for decryption, both of which are used to manage the password. If you want to know more about the library, you can see more details in the help functions. Next, we have to create a txt file with your encrypted passwords:$ServerName = "Server1" $UserName = "Login1" $Password = "Senha1" $PasswordToEncrypt = "YourPassword" $UserNameEncrypt = Write-EncryptedString -inputstring $UserName -Password $PasswordToEncrypt $PasswordEncrypt = Write-EncryptedString -inputstring $Password -Password $PasswordToEncrypt "$($Servername),$($UserNameEncrypt),$($PasswordEncrypt)" | Out-File c:\temp\ServersSecurePassword.txt -Append $ServerName = "Server2" $UserName = "Login2" $Password = "senha2" $PasswordToEncrypt = "YourPassword" $UserNameEncrypt = Write-EncryptedString -inputstring $UserName -Password $PasswordToEncrypt $PasswordEncrypt = Write-EncryptedString -inputstring $Password -Password $PasswordToEncrypt "$($Servername),$($UserNameEncrypt),$($PasswordEncrypt)" | Out-File c:\temp\ ServersSecurePassword.txt -Append .And in the c:\temp\ServersSecurePassword.txt file which we've just created, you will find your Username and Password, all neatly encrypted. Let's take a look at what the txt looks like: .and in case you're wondering, Server names, Usernames and Passwords are all separated by commas. Decryption is actually much more simple:Read-EncryptedString -InputString $EncryptString -password "YourPassword" (Just remember that the Password you're trying to decrypt must be exactly the same as the encrypted phrase.) Finally, just to show you how smooth this solution is, let's say I want to use the Invoke-DBMaint function from SQLPSX to perform a checkdb on a system database: it's just a case of split, decrypt and be happy!Get-Content c:\temp\ServerSecurePassword.txt | foreach { [array] $Split = ($_).split(",") Invoke-DBMaint -server $($Split[0]) -UserName (Read-EncryptedString -InputString $Split[1] -password "YourPassword" ) -Password (Read-EncryptedString -InputString $Split[2] -password "YourPassword" ) -Databases "SYSTEM" -Action "CHECK_DB" -ReportOn c:\Temp } This is why I love Powershell.

• Subterranean IL: Volatile

  - by Simon Cooper

  This time, we'll be having a look at the volatile. prefix instruction, and one of the differences between volatile in IL and C#. The volatile. prefix volatile is a tricky one, as there's varying levels of documentation on it. From what I can see, it has two effects: It prevents caching of the load or store value; rather than reading or writing to a cached version of the memory location (say, the processor register or cache), it forces the value to be loaded or stored at the 'actual' memory location, so it is then immediately visible to other threads. It forces a memory barrier at the prefixed instruction. This ensures instructions don't get re-ordered around the volatile instruction. This is slightly more complicated than it first seems, and only seems to matter on certain architectures. For more details, Joe Duffy has a blog post going into the details. For this post, I'll be concentrating on the first aspect of volatile. Caching field accesses To demonstrate this, I created a simple multithreaded IL program. It boils down to the following code: .class public Holder { .field public static class Holder holder .field public bool stop .method public static specialname void .cctor() { newobj instance void Holder::.ctor() stsfld class Holder Holder::holder ret }}.method private static void Main() { .entrypoint // Thread t = new Thread(new ThreadStart(DoWork)) // t.Start() // Thread.Sleep(2000) // Console.WriteLine("Stopping thread...") ldsfld class Holder Holder::holder ldc.i4.1 stfld bool Holder::stop call instance void [mscorlib]System.Threading.Thread::Join() ret}.method private static void DoWork() { ldsfld class Holder Holder::holder // while (!Holder.holder.stop) {} DoWork: dup ldfld bool Holder::stop brfalse DoWork pop ret} If you compile and run this code, you'll find that the call to Thread.Join() never returns - the DoWork spinlock is reading a cached version of Holder.stop, which is never being updated with the new value set by the Main method. Adding volatile to the ldfld fixes this: dupvolatile.ldfld bool Holder::stopbrfalse DoWork The volatile ldfld forces the field access to read direct from heap memory, which is then updated by the main thread, rather than using a cached copy. volatile in C# This highlights one of the differences between IL and C#. In IL, volatile only applies to the prefixed instruction, whereas in C#, volatile is specified on a field to indicate that all accesses to that field should be volatile (interestingly, there's no mention of the 'no caching' aspect of volatile in the C# spec; it only focuses on the memory barrier aspect). Furthermore, this information needs to be stored within the assembly somehow, as such a field might be accessed directly from outside the assembly, but there's no concept of a 'volatile field' in IL! How this information is stored with the field will be the subject of my next post.

• The Case for Complimentary Software Copies

  - by GGBlogger

  As the Geriatric Geek you can understand that I’ve been writing and studying for over 60 years. That means that I’ve seen insane changes in the computer software industry. I’ve made the joke that I get a new college education every 6 months or so. Of course that’s an exaggeration but it doesn’t make the feeling go away. I have a long standing and strong relationship with Microsoft so I’m armed with virtually every tool they make. It also means that I have access to tons of training material. But here’s the rub… Last year I started a definitive read of Professional Visual Basic 2008. The purpose was to fill in holes in my understanding of various things. I’m currently on page 1119 of some 1400 pages. During this sojourn I’ve decided that the future is web related which is to say that the future of “thick client” applications running as Windows applications is likely to slowly disappear. To that end I’ve taken a side trip or two into the world of ASP (including XML), Silverlight and cloud development. After carefully avoiding (that’s tongue in cheek) XML for years I finally had to bite the bullet, so to speak, and start learning XML in earnest. The most recent result of that was trail downloads of Altova’s MissionKit 2010 for Software Architects and Liquid Technologies Liquid XML Studio Developer Edition. These are both beautiful products and I want to learn them and write about them. Now comes the rub… While 30 day evaluations are generous in allowing casual users to assess these technologies for purchase they are NOT long enough to allow an author to evaluate, learn and ultimately write about them. Even if I devoted the full 30 days to learning, using and writing about say Altova’s suite I wouldn’t have enough time. Liquid XML may be a little easier to learn (one product as opposed to 8).  Add to that the fact that I frequently get sidetracked to add to my kit and it really blows out. It can be extremely frustrating when I’ve devoted hours to a project and suddenly discover that to complete it I will either need to purchase a license or abandon the project. Since my life blood does not depend on the product I end up abandoning the project and moving on. So to the folks from whom I request complimentary copies… I guarantee that if I convert your product to doing paid development work I will purchase a license to do that but as long as I am using your product to study for the purpose of writing samples, teaching use or otherwise promoting your product to other paying customers I will ask that you give me a license so that I can do that without facing the dread expiration of a 30 day trial.

• Hadoop, NOSQL, and the Relational Model

  - by Phil Factor

  (Guest Editorial for the IT Pro/SysAdmin Newsletter)Whereas Relational Databases fit the world of commerce like a glove, it is useless to pretend that they are a perfect fit for all human endeavours. Although, with SQL Server, we’ve made great strides with indexing text, in processing spatial data and processing markup, there is still a problem in dealing efficiently with large volumes of ephemeral semi-structured data. Key-value stores such as Cassandra, Project Voldemort, and Riak are of great value for ephemeral data, and seem of equal value as a data-feed that provides aggregations to an RDBMS. However, the Document databases such as MongoDB and CouchDB are ideal for semi-structured data for which no fixed schema exists; analytics and logging are obvious examples. NoSQL products, such as MongoDB, tackle the semi-structured data problem with panache. MongoDB is designed with a simple document-oriented data model that scales horizontally across multiple servers. It doesn’t impose a schema, and relies on the application to enforce the data structure. This is another take on the old ‘EAV’ problem (where you don’t know in advance all the attributes of a particular entity) It uses a clever replica set design that allows automatic failover, and uses journaling for data durability. It allows indexing and ad-hoc querying. However, for SQL Server users, the obvious choice for handling semi-structured data is Apache Hadoop. There will soon be an ODBC Driver for Apache Hive .and an Add-in for Excel. Additionally, there are now two Hadoop-based connectors for SQL Server; the Apache Hadoop connector for SQL Server 2008 R2, and the SQL Server Parallel Data Warehouse (PDW) connector. We can connect to Hadoop process the semi-structured data and then store it in SQL Server. For one steeped in the culture of Relational SQL Databases, I might be expected to throw up my hands in the air in a gesture of contempt for a technology that was, judging by the overblown journalism on the subject, about to make my own profession as archaic as the Saggar makers bottom knocker (a potter’s assistant who helped the saggar maker to make the bottom of the saggar by placing clay in a metal hoop and bashing it). However, on the contrary, I find that I'm delighted with the advances made by the NoSQL databases in the past few years. Having the flow of ideas from the NoSQL providers will knock any trace of complacency out of the providers of Relational Databases and inspire them into back-fitting some features, such as horizontal scaling, with sharding and automatic failover into SQL-based RDBMSs. It will do the breed a power of good to benefit from all this lateral thinking.

• Why enumerator structs are a really bad idea (redux)

  - by Simon Cooper

  My previous blog post went into some detail as to why calling MoveNext on a BCL generic collection enumerator didn't quite do what you thought it would. This post covers the Reset method. To recap, here's the simple wrapper around a linked list enumerator struct from my previous post (minus the readonly on the enumerator variable): sealed class EnumeratorWrapper : IEnumerator<int> { private LinkedList<int>.Enumerator m_Enumerator; public EnumeratorWrapper(LinkedList<int> linkedList) { m_Enumerator = linkedList.GetEnumerator(); } public int Current { get { return m_Enumerator.Current; } } object System.Collections.IEnumerator.Current { get { return Current; } } public bool MoveNext() { return m_Enumerator.MoveNext(); } public void Reset() { ((System.Collections.IEnumerator)m_Enumerator).Reset(); } public void Dispose() { m_Enumerator.Dispose(); } } If you have a look at the Reset method, you'll notice I'm having to cast to IEnumerator to be able to call Reset on m_Enumerator. This is because the implementation of LinkedList<int>.Enumerator.Reset, and indeed of all the other Reset methods on the BCL generic collection enumerators, is an explicit interface implementation. However, IEnumerator is a reference type. LinkedList<int>.Enumerator is a value type. That means, in order to call the reset method at all, the enumerator has to be boxed. And the IL confirms this: .method public hidebysig newslot virtual final instance void Reset() cil managed { .maxstack 8 L_0000: nop L_0001: ldarg.0 L_0002: ldfld valuetype [System]System.Collections.Generic.LinkedList`1/Enumerator<int32> EnumeratorWrapper::m_Enumerator L_0007: box [System]System.Collections.Generic.LinkedList`1/Enumerator<int32> L_000c: callvirt instance void [mscorlib]System.Collections.IEnumerator::Reset() L_0011: nop L_0012: ret } On line 0007, we're doing a box operation, which copies the enumerator to a reference object on the heap, then on line 000c calling Reset on this boxed object. So m_Enumerator in the wrapper class is not modified by the call the Reset. And this is the only way to call the Reset method on this variable (without using reflection). Therefore, the only way that the collection enumerator struct can be used safely is to store them as a boxed IEnumerator<T>, and not use them as value types at all.

• The Birth of SSAS Compare

  - by Red Gate Software BI Tools Team

  Noemi Moreno, Red Gate Business Intelligence Specialist Software vendors – even Microsoft – tend to forget about the needs of business intelligence developers. We are a rare and rather invisible species. For example, BIDS remained in VS 2008 until SQL Server 2012. It took until this release before we got something as simple as an “undo” function. Before I joined Red Gate as a BI specialist, I worked on SQL Development. I’ll never forget the time I discovered Red Gate’s SQL Compare tool and how it reduced the task of preparing a database release from a couple of days to ten minutes. When I moved to SSAS, MDX and cubes, I became frustrated with the deployment process because I couldn’t find a tool that made Cube releases as easy as they are with SQL Compare. This became my quest. I pitched the idea to a few people in Red Gate’s regular Down Tools Week, when everyone puts down their day-to-day tasks and works on their own projects. My task was to reason with a roomful of cynical developers, hardened to the blandishments of project managers, for help to develop a tool that would compare two different SSAS databases and create the script to process only the objects that needed processing, thereby reducing release time to only a few minutes. I walked to the podium and gave them the full story of the distressed BI specialists, doomed to spend tedious hours preparing deployment scripts. A few developers recovered from their torpor to cast a languid eye at my presentation. It wasn’t enough. In a sudden impulse, I blurted out a promise to perform a flamenco dance for just the team if the tool was able to successfully compare two SSAS databases and generate a script by the end of the week. I was lucky enough that some of them believed me and jumped in: David Pond (Dev), Matt Burton (Dev), Tilman Bregler (Dev), Shobana Sekar (Test), Ruchija Raj (Test), Nick Sutherland (Product Manager) and Irma Tanovic (BI). They didn’t know that Irma and I would be away on a conference in Amsterdam and would leave them without our support. But to my surprise, they had a working tool by the time we came back – basic, and with a few bugs, but a working tool nonetheless! Seeing it compare a very basic SSAS database, detect the changes and generate the scripts was amazing! Something that normally takes half a day was done in under a minute. Since then, a few months have passed and a BI Tools team has been created at Red Gate to work full time on BI tools for BI developers, starting with SSAS Compare. How cool is that? So download the free beta and give us your feedback. And the flamenco? I still need to deliver that. Tilman reminds me every day! I need to get the full flamenco costume.

• Antenna Aligner Part 5: Devil is in the detail

  - by Chris George

  "The first 90% of a project takes 90% of the time and the last 10% takes the another 200%"  (excerpt from onista) Now that I have a working app (more or less), it's time to make it pretty and slick. I can't stress enough how useful it is to get other people using your software, and my simple app is no exception. I handed my iPhone to a couple of my colleagues at Red Gate and asked them to use it and give me feedback. Immediately it became apparent that the delay between the list page being shown and the list being drawn was too long, and everyone who tried the app clicked on the "Recalculate" button before it had finished. Similarly, selecting a transmitter heralded a delay before the compass page appeared with similar consequences. All users expected there to be some sort of feedback/spinny etc. to show them it is actually doing something. In a similar vein although for opposite reasons, clicking the Recalculate button did indeed recalculate the available transmitters and redraw them, but it did this too fast! One or two users commented that they didn't know if it had done anything. All of these issues resulted in similar solutions; implement a waiting spinny. Thankfully, jquery mobile has one built in, primarily used for ajax operations. Not wishing to bore you with the many many iterations I went through trying to get this to work, I'll just give you my solution! (Seriously, I was working on this most evenings for at least a week!) The final solution for the recalculate problem came in the form of the code below. $(document).on("click", ".show-page-loading-msg", function () {            var $this = $(this),                theme = $this.jqmData("theme") ||                        $.mobile.loadingMessageTheme;            $.mobile.showPageLoadingMsg(theme, "recalculating", false);            setTimeout(function ()                           { $.mobile.hidePageLoadingMsg(); }, 2000);            getLocationData();        })        .on("click", ".hide-page-loading-msg", function () {              $.mobile.hidePageLoadingMsg();        }); The spinny is activated by setting the class of a button (for example) to the 'show-page-loading-msg' class. &lt;a data-role="button" class="show-page-loading-msg"Recalculate This means the code above is fired, calling the showPageLoadingMsg on the document.mobile object. Then, after a 2 second timeout, it calls the hidePageLoadingMsg() function. Supposedly, it should show "recalculating" underneath the spinny, but I've not got that to work. I'm wondering if there is a problem with the jquery mobile implementation. Anyway, it doesn't really matter, it's the principle I'm after, and I now have spinnys!

• Some Problems Can't Be Outsourced

  - by mikef

  More and more companies are becoming attracted to the idea of Infrastructure as a Service (or IaaS). It would seem that you can outsource the provisioning and management of your services, encompassing everything from Email, through to your servers, workstations and software, all the way down to your LAN and internet services. This type of outsourcing can be a very attractive option for companies who have tight budgets who are short of technical skills or don't have the means to provide long-term IT support. Essentially, they can outsource your services at low short-term costs that are knowable and controllable, are quickly and easily scalable, and generate a minimum of hassle for your internal staff. If you want to get a sophisticated IT infrastructure set up in a hurry without the usual high buy-in costs, or the task of finding and hiring the right specialists. It would seem the way to go, particularly when their salesmen are hypnotizing you with oleaginous phrases such as "we are closely aligned with our client organization's core business requirements, providing agile services". It sounds too good to be true, and so it is. Whereas the costs will have initially been calculated on the annual renewal fees and service fees for ongoing support, there are other charges too which aren't so obvious. It can end up costing far more than the conventional solution once you take into account the extra costs, the fees for customization and upgrades. The Total Cost of Ownership (TCO) only becomes apparent when it is too late to extract the company easily from the arrangement. After a few years, these annual fees can add up to more than the initial cost of implementing a traditional in-house system. Worse than that is that you can then lose your power to determine your priorities: When you become reliant on this company, with its own schedule of priorities, to implement every change, however simple, you have effectively lost control of your technical infrastructure. This will make senior management very nervous. There is definitely a requirement for this sort of service. If you urgently need an exceptionally high class of service or more expertise than you currently possess, then outsourcing is probably for you. You and your IT colleagues will always have something to do, be it user assistance, smoothing out integrations with an external provider, or working on something entirely new. Heck, if you outsource to IBM, the SysAdmins can go along for the ride and polish their expertise. What you need to figure out is how much your time is worth, because time is ultimately all that outsourcing will buy you and your organization. Now you just need to convince your nervous CEO. Cheers, Michael

• Silverlight 4 Twitter Client &ndash; Part 5

  - by Max

  In this post, we will look at implementing the following in our twitter client - displaying the profile picture in the home page after logging in. So to accomplish this, we will need to do the following steps. 1) First of all, let us create another field in our Global variable static class to hold the profile image url. So just create a static string field in that. public static string profileImage { get; set; } 2) In the Login.xaml.cs file, before the line where we redirect to the Home page if the login was successful. Create another WebClient request to fetch details from this url - .xml">http://api.twitter.com/1/users/show/<TwitterUsername>.xml I am interested only in the “profile_image_url” node in this xml string returned. You can choose what ever field you need – the reference to the Twitter API Documentation is here. 3) This particular url does not require any authentication so no need of network credentials for this and also the useDefaultCredentials will be true. So this code would look like. WebRequest.RegisterPrefix("http://", System.Net.Browser.WebRequestCreator.ClientHttp); WebClient myService = new WebClient(); myService.AllowReadStreamBuffering = myService.UseDefaultCredentials = true; myService.DownloadStringCompleted += new DownloadStringCompletedEventHandler(TimelineRequestCompleted_User);) myService.DownloadStringAsync(new Uri("http://api.twitter.com/1/users/show/" + TwitterUsername.Text + ".xml")); 4) To parse the xml file returned by this and get the value of the “profile_image_url” node, the LINQ code will look something like XDocument xdoc; xdoc = XDocument.Parse(e.Result); var answer = (from status in xdoc.Descendants("user") select status.Element("profile_image_url").Value); GlobalVariable.profileImage = answer.First().ToString(); 5) After this, we can then redirect to Home page completing our login formalities. 6) In the home page, add a image tag and give it a name, something like <Image Name="image1" Stretch="Fill" Margin="29,29,0,0" Height="73" VerticalAlignment="Top" HorizontalAlignment="Left" Width="73" /> 7) In the OnNavigated to event in home page, we can set the image source url as below image1.Source = new BitmapImage(new Uri(GlobalVariable.profileImage, UriKind.Absolute)); Hope this helps. If you have any queries / suggestions, please feel free to comment below or contact me. Technorati Tags: Silverlight,LINQ,Twitter API,Twitter

• menuitem id in xml format can't be an integer? huh. really?

  - by misbell

  ok, in menu.add, you add an integer menuitem id. But when you specify the menu in xml, @+id can't take an integer, so you can't test the id for the menu item as an integer in a switch statement. What obvious thing am I missing, because surely an inconsistency this bone-stupid couldn't have passed muster with all those wonderful geniuses at Google. on top of that, when I give the menu item a name like "@+id/myMenuItem", item.getItemId() returns an integer, a long one, which I guess is a representation of the hex pointer.

• Unauthorized Sharepoint WSDL from Coldfusion 8

  - by antony.trupe

  How do I solve the error: Unable to read WSDL from URL: https://workflowtest.site.edu/_vti_bin/Lists.asmx?WSDL. Error: 401 Unauthorized. I can successfully view the WSDL from the browser using the same user account. I'm not sure which authentication is being used (Basic or Integrated). How would I find that out? The code making the call is: <cfinvoke username="username" password="password" webservice="https://workflowtest.liberty.edu/_vti_bin/Lists.asmx?WSDL" method="GetList" listName="{CB02EB71-392E-4906-B512-8EC002F72436}" > The impression I get is that coldfusion doesn't like being made to authenticate to get the WSDL.

• Weblogic Bea 10.0 M1 and WorkManager

  - by ma-ver-ick

  Hi there! I have to execute long running threads in a WebLogic Bea 10.0 M1 server environment. I tried to use WorkManagers for this. Using an own WorkManager allows me to specify my own thread timeout (MaxThreadStuckTime) instead of adjusting the timeout for the whole business application. My setup is as follows: weblogic-ejb-jar.xml: <?xml version="1.0" encoding="UTF-8"?> <weblogic-ejb-jar xmlns="http://www.bea.com/ns/weblogic/90" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.bea.com/ns/weblogic/90 http://www.bea.com/ns/weblogic/90/weblogic-ejb-jar.xsd"> <weblogic-enterprise-bean> <ejb-name>TestBean</ejb-name> <resource-description> <res-ref-name>myWorkManager</res-ref-name> <jndi-name>wm/myWorkManager</jndi-name> </resource-description> </weblogic-enterprise-bean> </weblogic-ejb-jar> weblogic-application.xml: <?xml version="1.0" encoding="UTF-8"?> <weblogic xmlns="http://www.bea.com/ns/weblogic/90" xmlns:j2ee="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.bea.com/ns/weblogic/90 http://www.bea.com/ns/weblogic/90/weblogic.xsd"> <work-manager> <name>myWorkManager</name> <ignore-stuck-threads>1</ignore-stuck-threads> </work-manager> </weblogic> and the Bean: import javax.annotation.Resource; import javax.ejb.Stateful; import weblogic.work.WorkManager; @Stateful(mappedName = "TestBean") public class TestBean implements TestBeanRemote { @Resource(name = "myWorkManager") private WorkManager myWorkManager; public void test() { myWorkManager.schedule(new Runnable() { public void run() { while (true) { System.out.println("test: +++++++++++++++++++++++++"); try { Thread.sleep(45000); } catch (InterruptedException e) { e.printStackTrace(); } } } }); } } When I try to deploy this things, the server gives me the following exceptions: [EJB:011026]The EJB container failed while creating the java:/comp/env namespace for this EJB deployment. weblogic.deployment.EnvironmentException: [EJB:010176]The resource-env-ref 'myWorkManager' declared in the ejb-jar.xml descriptor has no JNDI name mapped to it. The resource-ref must be mapped to a JNDI name using the resource-description element of the weblogic-ejb-jar.xml descriptor. I try to figure out how to access / use WorkMangers for days now, and still get this or that as an exception. Very frustrating! Thanks in advance!

• Specifying Android project dependencies (in Eclipse)

  - by Henrik Gustafsson

  I have two Android projects, a 'library project' containing a custom layout, and an 'application project' containing an application which uses the layout. Everything seems to build and execute fine, except that the visual layout editor throws a ClassNotFoundException (which I assume is a bug in the plug-in), but when I try to start to make use of the attributes I defined for the custom layout in the xml, I can no longer build. That is; this works: <?xml version="1.0" encoding="utf-8"?> <se.fnord.android.layout.PredicateLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent"> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="asdfasdf" /> </se.fnord.android.layout.PredicateLayout> Whereas this does not: <?xml version="1.0" encoding="utf-8"?> <se.fnord.android.layout.PredicateLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:fnord="http://schemas.android.com/apk/res/se.fnord.android" android:layout_width="fill_parent" android:layout_height="fill_parent"> <TextView fnord:layout_horizontalSpacing="1px" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="asdfasdf" /> </se.fnord.android.layout.PredicateLayout> The build fails with a message from aapt: ERROR No resource identifier found for attribute 'layout_horizontalSpacing' in package 'se.fnord.android' The resource identifier does exist in the R-file and attrs.xml contained the library project, and if I put the layout code and resources directly in the application project everything works fine. The layout_horizontalSpacing attribute (and layout_verticalSpacing) is a custom attribute used in the PredicateLayout.LayoutParam class to specify the distance to the next widget. So far I've tried the standard eclipse ways by specifying project references and build path project dependencies. I was also told to try the tag in the application manifest, which did not help. So, what do I need to do for the references in the xml-file to work? I don't know if it's relevant, but the 'library' manifest looks like this: <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="se.fnord.android" android:versionCode="1" android:versionName="1.0.0"> </manifest> The 'application' manifest like this: <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="se.fnord.appname" android:versionCode="1" android:versionName="1.0.0"> <application android:icon="@drawable/icon" android:label="@string/app_name"> <activity android:name=".AppName" android:label="@string/app_name"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> </application> </manifest> (The 'PredicateLayout', btw, is a cleaned-up version of this).

The problem comes when I try to call a method from the webservice: String a = (String)webservice.userProfileServices(xml); I'm also using the following SOAP headers: esgGatewayPort = (new EsgGatewayLocator()).getesgGatewayPort(); //setting the authentication header PrefixedQName name = new PrefixedQName("http://schemas.xmlsoap.org/ws/2002/07/secext","Security","wsse"); System.out.println("Setting headers for authentication"); org.apache.axis.message.SOAPHeaderElement sh = new org.apache.axis.message.SOAPHeaderElement(name); SOAPElement sub; try { String clntUserName="myUser"; String clntPassword="myPassword"; sub = sh.addChildElement("UsernameToken"); SOAPElement element = sub.addChildElement("Username"); element.addTextNode(clntUserName); element = sub.addChildElement("Password"); element.addTextNode(clntPassword); ((org.apache.axis.client.Stub) esgGatewayPort).setHeader(sh); } catch (SOAPException e) { e.printStackTrace(); } I receive the following: AxisFault faultCode: {http://schemas.xmlsoap.org/soap/envelope/}Server.userException faultSubcode: faultString: org.xml.sax.SAXException: Bad envelope tag: HTML faultActor: faultNode: faultDetail: {http://xml.apache.org/axis/}stackTrace:org.xml.sax.SAXException: Bad envelope tag: HTML at org.apache.axis.message.EnvelopeBuilder.startElement(EnvelopeBuilder.java:71) at org.apache.axis.encoding.DeserializationContext.startElement(DeserializationContext.java:1048) at com.sun.org.apache.xerces.internal.parsers.AbstractSAXParser.startElement(Unknown Source) at com.sun.org.apache.xerces.internal.impl.XMLNSDocumentScannerImpl.scanStartElement(Unknown Source) at com.sun.org.apache.xerces.internal.impl.XMLNSDocumentScannerImpl$NSContentDriver.scanRootElementHook(Unknown Source) at com.sun.org.apache.xerces.internal.impl.XMLDocumentFragmentScannerImpl$FragmentContentDriver.next(Unknown Source) at com.sun.org.apache.xerces.internal.impl.XMLDocumentScannerImpl$PrologDriver.next(Unknown Source) at com.sun.org.apache.xerces.internal.impl.XMLDocumentScannerImpl.next(Unknown Source) at com.sun.org.apache.xerces.internal.impl.XMLNSDocumentScannerImpl.next(Unknown Source) at com.sun.org.apache.xerces.internal.impl.XMLDocumentFragmentScannerImpl.scanDocument(Unknown Source) at com.sun.org.apache.xerces.internal.parsers.XML11Configuration.parse(Unknown Source) at com.sun.org.apache.xerces.internal.parsers.XML11Configuration.parse(Unknown Source) at com.sun.org.apache.xerces.internal.parsers.XMLParser.parse(Unknown Source) at com.sun.org.apache.xerces.internal.parsers.AbstractSAXParser.parse(Unknown Source) at com.sun.org.apache.xerces.internal.jaxp.SAXParserImpl$JAXPSAXParser.parse(Unknown Source) at weblogic.xml.jaxp.WebLogicXMLReader.parse(WebLogicXMLReader.java:133) at weblogic.xml.jaxp.RegistryXMLReader.parse(RegistryXMLReader.java:153) at javax.xml.parsers.SAXParser.parse(Unknown Source) at org.apache.axis.encoding.DeserializationContext.parse(DeserializationContext.java:227) at org.apache.axis.SOAPPart.getAsSOAPEnvelope(SOAPPart.java:696) at org.apache.axis.Message.getSOAPEnvelope(Message.java:435) at org.apache.axis.transport.http.HTTPSender.readFromSocket(HTTPSender.java:796) at org.apache.axis.transport.http.HTTPSender.invoke(HTTPSender.java:144) at org.apache.axis.strategies.InvocationStrategy.visit(InvocationStrategy.java:32) at org.apache.axis.SimpleChain.doVisiting(SimpleChain.java:118) at org.apache.axis.SimpleChain.invoke(SimpleChain.java:83) at org.apache.axis.client.AxisClient.invoke(AxisClient.java:165) at org.apache.axis.client.Call.invokeEngine(Call.java:2784) at org.apache.axis.client.Call.invoke(Call.java:2767) at org.apache.axis.client.Call.invoke(Call.java:2443) at org.apache.axis.client.Call.invoke(Call.java:2366) at org.apache.axis.client.Call.invoke(Call.java:1812) Any help will be truly appreciated David

• Displaytag table exported header column contains span tags

  - by Lancelot

  Hi, When I export the content of the display tag table I use the data shows up fine, but the header cells are surrounded by html span tags, which is slightly annoying. I can imagine why Displaytag uses spans around the column header's text, but it shouldn't transpose in the exported data I think. Here is my displaytag.properties config related to export: # Export export.amount = list export.decorated = true export.banner=<div id="exportTypes"><span class="label">Export: </span>{0}</div> export.banner.sepchar=&nbsp;| export.types=excel csv xml export.excel=true export.csv=true export.xml=false export.excel.label=xls export.csv.label=csv export.xml.label=xml export.excel.filename=export.xls export.csv.filename=export.csv export.xml.filename=export.xml export.excel.include_header=true export.csv.include_header=true export.xml.include_header=true Here is the displaytag table itself: <display:table class="list sortable" defaultsort="1" export="true" htmlId="contacts" id="row" name="contacts" requestURI=""> <display:setProperty name="export.banner"><div id="exportTypes"><span class="label">Export:</span> {0}</div></display:setProperty> <display:setProperty name="export.csv.filename">CSV</display:setProperty> <display:setProperty name="export.excel.filename">XLS</display:setProperty> <display:setProperty name="basic.msg.empty_list_row"> <tr class="empty"> <td colspan="7">Empty</td> </tr> </display:setProperty> <display:column class="lastName" property="lastName" sortProperty="lastName" headerClass="lastName first" sortable="true" titleKey="Lastname" href="contact/view" paramId="contactId" paramProperty="id" /> <display:column property="firstName" class="firstName" headerClass="firstName" sortable="true" titleKey="FirstName" /> <display:column class="loginName" headerClass="loginName" sortable="true" titleKey="Username" /> </display:table> My problem is when I click export on either the CSV or the XLS format the header row in the generated file looks like this: <span>Last Name</span> <span>First Name</span> <span>Username</span> I really don't want those span tags in there, any way to work around that? Thanks

• dojo/dijit ContentPane setting content

  - by Kitson

  I am trying append some XML retrieved via a dojo.XHRGet to a dijit.layout.ContentPane. Everything works ok in Firefox (3.6) but in Chrome, I only get back 'undefined' in the particular ContentPane. My code looks something like this: var cp = dijit.byId("mapDetailsPane"); cp.destroyDescendants(); // there are some existing Widgets/content I want to clear // and replace with the new content var xhrData = { url : "getsomexml.php", handleAs: "xml", preventCache: true, failOk: true }; var deferred = new dojo.xhrGet(xhrData); deferred.addCallback(function(data) { console.log(data.firstChild); // get a DOM object in both Firebug // and Chrome Dev Tools cp.attr("content",data.firstChild); // get the XML appended to the doc in Firefox, // but "undefined" in Chrome }); Because in both browsers I get back a valid Document object I know XHRGet is working fine, but there seems to be some sort of difference in how the content is being set. Is there a better way to handle the return data from the request? There was a request to see my XML, so here is part of it... <?xml version="1.0" encoding="UTF-8" standalone="no"?> <svg xmlns:svg="http://www.w3.org/2000/svg" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" version="1.1" width="672" height="1674"> <defs> <style type="text/css"> <![CDATA[ ...bunch of CSS... ]]> </style> <marker refX="0" refY="0" orient="auto" id="A00End" style="overflow: visible;"> ...bunch more defs... </defs> <g id="endpoints"> ...bunch of SVG with a some... <a xlink:href="javascript:gotoLogLine(16423,55);" xlink:type="simple">...more svg...</a> </g> </svg> I have run the output XML trough the WC3 validator for XML to verify it is valid. Like I said before, works in FireFox 3.6. I tried it on Safari and I got the same "undefined" so it seems to be related to Webkit.
