• Visual Studio opening .xml files in Notepad

  - by Portman

  So I'm happily working on a project making heavy use of custom .xml configuration files this morning. All of a sudden, whenever I double-click an .xml file in Solution Explorer, it opens in Notepad instead of within Visual Studio. Thinking that it was the Windows file associations, I right-clicked on a file in Explorer, selected Open With Choose Defaults, and selected Visual Studio 2008. But the problem remains -- now when I open a file from Explorer, Visual Studio Opens, then it opens Notepad. Needless to say, this is very frustrating, and Google is not much help. Has anyone else ever had this problem, and what did you do about it? Notes: This only happens for .xml files. Other text files (.config, .txt) open within Visual Studio just fine. This has nothing to do with Windows file associations, as Windows open up VS2008 just as it should. This is some crazy problem internal to Visual Studio. I've also tried Tools Options General Restore File Associations. No luck. Nothing present in Tools Options Text Editor File Extension This is what my "Open With" menu looks like for .xml files. As you can see, "XML Editor" is set to the default.

• PHPExcel reading columns

  - by user1270150

  I am new to using the PHPExcel and am struggling to implement a basic reader that can be used to read only specified columns, with all rows from a spreadsheet into an array, which I would like to present in a webpage. After reading the supplied documentation and examples, I am struggling to wrap my head round the implementation of a number of examples, so any help would be much appreciated. I am using the following code to get the contents of the default worksheet into an array: for ($row = 2; $row <= $highestRow; $row++) { $dataRow = $objWorksheet->rangeToArray('A'.$row.':'.$highestColumn.$row,null, true, true, true); if ((isset($dataRow[$row]['A'])) && ($dataRow[$row]['A'] > '')) { ++$r; foreach($headingsArray as $columnKey => $columnHeading) { $columnHeading = rtrim($columnHeading); $columnHeading = preg_replace('/\s+/', ' ',$columnHeading); $columnHeading = preg_replace('/\ /', '_',$columnHeading); $columnHeading = strtolower($columnHeading); $namedDataArray[$r][$columnHeading] = $dataRow[$row][$columnKey]; } } } Above code reads through all the columns and rows and builds and array, but I would like to be able to add a configuration array that will declare columns that should be read...sure this is possible, so any help would be much appreciated. Thanks

• How to send arbitrary ftp commands in C#

  - by cchampion

  I have implemented the ability to upload, download, delete, etc. using the FtpWebRequest class in C#. That is fairly straight forward. What I need to do now is support sending arbitrary ftp commands such as quote SITE LRECL=132 RECFM=FB or quote SYST Here's an example configuration straight from our app.config: <!-- The following commands will be executed before any uploads occur --> <extraCommands> <command>quote SITE LRECL=132 RECFM=FB</command> </extraCommands> I'm still researching how to do this using FtpWebRequest. I'll probably try WebClient class next. Anyone can point me in the right direction quicker? Thanks! UPDATE: I've come to that same conclusion, as of .NET Framework 3.5 FtpWebRequest doesn't support anything except what's in WebRequestMethods.Ftp.*. I'll try a third party app recommended by some of the other posts. Thanks for the help!

• After rich:extendedDataTable sortby,otheractions are not getting executed

  - by user118802

  I have a RichFaces UI which are having sidebar menu and sidebar had 8 links. I am using Seam @DataModel and @Factory and hibernate criteria to populate all the 8 pages. In all the pages i have sortby functionality which is working fine. I am able to get all data in all the 8 pages and I can freely navigate around all the links/xhtmls. But if in one of the xhtmlpages if I do sorting or groupby after that I am unable to navigate to other pages.If I select any other link the same last query which is executed for sorting is getting executed. Is this an issue? or do I need add any configuration. Please help me in solving this issue. Below is the codesnippet one of the 8 xhtml <rich:column sortable="true" sortBy="#{p.regionid}" width="100px" label="Region Id"> <f:facet name="header"> <h:outputText value="Region Id" /> </f:facet> <h:outputText value="#{p.regionid}" /> </rich:column> <rich:column sortable="true" sortBy="#{p.region}" width="100px" label="Region Name"> <f:facet name="header"> <h:outputText value="Region Name" /> </f:facet> <h:outputText value="#{p.region}" /> </rich:column> Sidebar Action @DataModel("regions") private List<CoreRegion> listRegions; @Factory("regions") public void getRegions() { System.out.println("Inside get Regions"); Session userDatabase = HibernateUtil.getSession(); Criteria crit = userDatabase.createCriteria(CoreRegion.class); listRegions = crit.list();

• Intellisense for custom config section problem with namespaces

  - by Quick Joe Smith

  I have just rolled a custom configuration section, created an accompanying schema document for Intellisense and added it to the Web.config's Schemas property as per Michael Stum's answer to another similar question. Unfortunately, and possibly due to me creating the XSD by hand with limited knowledge, the Intellisense relies on an xmlns attribute pointing to my XSD file's namespace being present in the custom config element. However, when running the project I get an Unrecognized attribute 'xmlns'. Note that attribute names are case-sensitive error. I could probably just modify my XSD file to define the xmlns attribute for that element, however I am wondering if this is just a bandaid fix to a larger problem. I must confess I don't have a very good understanding of XML namespaces so this might be an oppportunity to set me straight on a few things. Here is the attributes for my XSD file's root xs:schema element: <xs:schema id="awesomeConfig" targetNamespace="http://awesome.com/schemas" xmlns="http://awesome.com/schemas" elementFormDefault="qualified" xmlns:xs="http://www.w3.org/2001/XMLSchema"> ... </xs:schema> And on creating the element in the Web.config file, Visual Studio 2008 automatically appends: <awesomeConfig xmlns="http://awesome.com/schemas"></awesomeConfig> So have I misunderstood the meaning of the xs:schema attributes at all, or is the proper solution as simple as it seems?

• Looking for combinations of server and embedded database engines

  - by codeelegance

  I'm redesigning an application that will be run as both a single user and multiuser application. It is a .NET 2.0 application. I'm looking for server and embedded databases that work well together. I want to deploy the embedded database in the single user setup and of course, the server in the multiuser setup. Past releases have been based on MSDE but in the past year we've been having a lot of install issues: new installs hanging and leaving the system in an unknown state, upgrades disconnecting the database, etc. I migrated the application to SQL Server 2005 and the install is more reliable (as long as a user doesn't try to install over a broken MSDE installation). Since next year's release will be a complete redesign I figured now's the best time to address the database issue as well. The database has been abstracted from the rest of the application so I just need to choose which database(s) to use and write an implementation for each one. So far I've considered: SQL Server/ SQL Server Compact Edition Firebird (same DB engine is available in two different server modes and an embedded dll) Each has its own merits but I'm also interested in any other suggestions. This is a fairly simple program and its data requirements are simple as well. I don't expect it to strain whatever database I eventually choose. So easy configuration and deployment hold more weight than performance.

• C# webservice async callback not getting called on HTTP 407 error.

  - by Ben

  Hi, I am trying to test the use-case of a customer having a proxy with login credentials, trying to use our webservice from our client. If the request is synchronous, my job is easy. Catch the WebException, check for the 407 code, and prompt the user for the login credentials. However, for async requests, I seem to be running into a problem: the callback is never getting called! I ran a wireshark trace and did indeed see that the HTTP 407 error was being passed back, so I am bewildered as to what to do. Here is the code that sets up the callback and starts the request: TravelService.TravelServiceImplService svc = new TravelService.TravelServiceImplService(); svc.Url = svcUrl; svc.CreateEventCompleted += CbkCreateEventCompleted; svc.CreateEventAsync(crReq, req); And the code that was generated when I consumed the WSDL: public void CreateEventAsync(TravelServiceCreateEventRequest CreateEventRequest, object userState) { if ((this.CreateEventOperationCompleted == null)) { this.CreateEventOperationCompleted = new System.Threading.SendOrPostCallback(this.OnCreateEventOperationCompleted); } this.InvokeAsync("CreateEvent", new object[] { CreateEventRequest}, this.CreateEventOperationCompleted, userState); } private void OnCreateEventOperationCompleted(object arg) { if ((this.CreateEventCompleted != null)) { System.Web.Services.Protocols.InvokeCompletedEventArgs invokeArgs = ((System.Web.Services.Protocols.InvokeCompletedEventArgs)(arg)); this.CreateEventCompleted(this, new CreateEventCompletedEventArgs(invokeArgs.Results, invokeArgs.Error, invokeArgs.Cancelled, invokeArgs.UserState)); } } Debugging the WS code, I found that even the SoapHttpClientProtocol.InvokeAsync method was not calling its callback as well. Am I missing some sort of configuration?

• Logback: What would cause DEBUG - WARN to append to file but NOT ERROR?

  - by Zombies

  I am running a Java program from Eclipe, and I am using the logback console plugin. I can see the ERROR level statements being appended to console (as well as all of the others). But for some reason my file, which is correctly recieving new DEBUG-WARN statements, is NOT recieving the ERROR level ones. Here is my logback.xml: <consolePlugin /> <appender name="FILE" class="ch.qos.logback.core.FileAppender"> <file>logs/main.log</file> <layout class="ch.qos.logback.classic.PatternLayout"> <Pattern>%date %level [%thread] %logger{10} [%file:%line] %msg%n</Pattern> </layout> </appender> <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender"> <layout class="ch.qos.logback.classic.PatternLayout"> <Pattern>%msg%n</Pattern> </layout> </appender> <logger name="WebsiteChecker"> <appender-ref ref="FILE" /> </logger> <root> <level value="debug" /> <!--<appender-ref ref="STDOUT" />--> <appender-ref ref="FILE" /> </root> </configuration>

• Unity Framework constructor parameters in MVC

  - by ubersteve

  I have an ASP.NET MVC3 site that I want to be able to use different types of email service, depending on how busy the site is. Consider the following: public interface IEmailService { void SendEmail(MailMessage mailMessage); } public class LocalEmailService : IEmailService { public LocalEmailService() { // no setup required } public void SendEmail(MailMessage mailMessage) { // send email via local smtp server, write it to a text file, whatever } } public class BetterEmailService : IEmailService { public BetterEmailService (string smtpServer, string portNumber, string username, string password) { // initialize the object with the parameters } public void SendEmail(MailMessage mailMessage) { //actually send the email } } Whilst the site is in development, all of my controllers will send emails via the LocalEmailService; when the site is in production, they will use the BetterEmailService. My question is twofold: 1) How exactly do I pass the BetterEmailService constructor parameters? Is it something like this (from ~/Bootstrapper.cs): private static IUnityContainer BuildUnityContainer() { var container = new UnityContainer(); container.RegisterType<IEmailService, BetterEmailService>("server name", "port", "username", "password"); return container; } 2) Is there a better way of doing that - i.e. putting those keys in the web.config or another configuration file so that the site would not need to be recompiled to switch which email service it was using? Many thanks!

• Cassandra hot keyspace structure change

  - by Pierre

  Hello. I'm currently running a 12-node Cassandra cluster storing 4TB of data, with a replication factor set to 3. For the needs of an application update, we need to change the configuration of our keyspace, and we'd like to avoid any downtime if possible. I read on a mailing list that the best way to do it is to: Kill cassandra process on one server of the cluster Start it again, wait for the commit log to be written on the disk, and kill it again Make the modifications in the storage.xml file Rename or delete the files in the data directories according to the changes we made Start cassandra Goto 1 with next server on the list My questions would be: Did I understand the process well? Is there any risk of data corruption? During the process, there will be servers with different versions of the storage.xml file in the same cluser, same keyspace. Is it a problem? Same question as above if we not only add, rename and remove ColumnFamilies, but if we change the CompareWith parameter / transform an existing column family into a super one. Or do we need to change the name? Thank you for your answers. It's the first time I'll do this, and I'm a little bit scared.

• how do simple SQLAlchemy relationships work?

  - by Carson Myers

  I'm no database expert -- I just know the basics, really. I've picked up SQLAlchemy for a small project, and I'm using the declarative base configuration rather than the "normal" way. This way seems a lot simpler. However, while setting up my database schema, I realized I don't understand some database relationship concepts. If I had a many-to-one relationship before, for example, articles by authors (where each article could be written by only a single author), I would put an author_id field in my articles column. But SQLAlchemy has this ForeignKey object, and a relationship function with a backref kwarg, and I have no idea what any of it MEANS. I'm scared to find out what a many-to-many relationship with an intermediate table looks like (when I need additional data about each relationship). Can someone demystify this for me? Right now I'm setting up to allow openID auth for my application. So I've got this: from __init__ import Base from sqlalchemy.schema import Column from sqlalchemy.types import Integer, String class Users(Base): __tablename__ = 'users' id = Column(Integer, primary_key=True) username = Column(String, unique=True) email = Column(String) password = Column(String) salt = Column(String) class OpenID(Base): __tablename__ = 'openid' url = Column(String, primary_key=True) user_id = #? I think the ? should be replaced by Column(Integer, ForeignKey('users.id')), but I'm not sure -- and do I need to put openids = relationship("OpenID", backref="users") in the Users class? Why? What does it do? What is a backref?

• Rails routing problem

  - by Steve

  I am new to Rails routing and I currently have a problem and hope someone can explain it to me. I am using Rails 2.3.5 Firstly, let me describe my working-fine code: I have a text example, which has a controller (cars_controller) with an update action (along with some other actions). The update action needs the :id parameter. The edit.html.erb has a form: <% form_for :car, :url = {:controller = 'cars', :action = 'update' } % ... # rest of the form content. In the configuration/routes.rb, I have a self-defined routing rule for update: map.connect 'car/update/:id', :controller = 'cars', :action = 'update' This works fine. Secondly, I change the code. All I change is the self-defined routing rule to map.connect 'car/:action/:id, :controller = 'cars' To me, this rule covers the self-written routing rule. Of course, this rule is also used by other actions such as edit. But the edit.html.erb doesn't work. It complains that update action misses the :id parameter. I have to change the form_for helper to: <% form_for :car, :url = {:controller = 'cars', :action = 'update', :id = @car }% ... # @car is the instance passed to edit view. I know that if missing the :id parameter, update action will complain. What I don't understand is why my first code works (with my self-defined routing rule) but my second code fails. It seems to me that I didn't provide :id parameter in my self-defined routing rule. Anyone has an idea?

• Accessing web.config from Sharepoint web part

  - by philj

  I have a VS 2008 web parts project - in this project is a web.config file: something like this: <?xml version="1.0"?> <configuration> <connectionStrings/> <system.web> <appSettings> <add key="MFOwner" value="Blah" /> </appSettings> ……. In my web part I am trying to access values in the appSetting section: I've tried all of the code below and each returns null: string Owner = ConfigurationManager.AppSettings.Get("MFOwner"); string stuff1 = ConfigurationManager.AppSettings["MFOwner"]; string stuff3 = WebConfigurationManager.AppSettings["MFOwner"]; string stuff4 = WebConfigurationManager.AppSettings.Get("MFOwner"); string stuff2 = ConfigurationManager.AppSettings["MFowner".ToString()]; I've tried this code I found: NameValueCollection sAll; sAll = ConfigurationManager.AppSettings; string a; string b; foreach (string s in sAll.AllKeys) { a = s; b = sAll.Get(s); } and stepped through it in debug mode - that is getting things like : FeedCacheTimer FeedPageURL FeedXsl1 ReportViewerMessages which is NOT coming from anything in my web.config file....maybe a config file in sharepoint itself? How do I access a web.config (or any other kind of config file!) local to my web part??? thanks, Phil J

• Netbeans (PHP) catching syntax error on xml declaration

  - by Mike Valeriano

  Hello. I've just installed and configured Netbeans to work with PHP (including xdebug), and almost everything is working as intended, except that I've been getting "errors" in the IDE after I edited the default webpage template to comply with xhtml 1.1. The template is this: <?xml version="1.0" encoding="${project.encoding}" ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=${project.encoding}" /> <title></title> </head> <body> </body> </html> These are the errors I receive (I can't post images yet). Page is created OK, character encoding is inherited from project's settings as expected. It's probably something to do with the xml declaration on top of the document, but I don't really know how to "tune" Netbeans to ignore it and not show the 3 errors on every page I create. The warning is there because NB does not recognize the xhtml 1.1 DTD, so it falls back to html 4.01, which does not support the xmlns attribute in the html tag - and that's the only thing I could find searching around. It will be fixed in the next version, so I'm not worried about it. I know there's nothing wrong with the markup, but there's probably something I'm missing in NB configuration, and I would like to get rid of those messages because they pretty much take all the space I reserve for errors/warnings/tasks. So is there any way I can either make NB recognize this xml declaration or make it ignore these specific "errors"? Thanks.

• what are all the Optimize tricks that you know for asp.net code ?

  - by Aristos

  After some time of many code programming on asp.net, I discover the very big speed different between string and StringBuilder. I know that is very common and known but I just mention it for start. The second think that I have found to speed up the code, is to use the const, and not the static, for declare my configuration constants value (especial the strings). With the const, the compiler not create new object, but just place the value, on the point that you have ask it, but with the static declaration, is create a new memory object and keep its on the memory. My third trick, is when I search for string, I use hash values, and not the string itself. For example, if I need a List<string SomeValues, and place inside strings that I need to search them, I prefer to use List<int SomeHashValue, and I use the hash value to locate the strings. My forth thought that I was wandering, is if is better to place big strings in one line, or separate them in different lines with the + symbol to be more easy to read out. I make some tests and see that the compiler make a good job is some split the string, in many lines, using the + symbol. What other tricks/tips do you know and use on your programming to make it run faster, and maybe use less memory. Well I know, that some times, to make something run faster, you need more memory, more cache. My priority is on speed. Because Speed Counts.

• What's next for all of these Microsoft "overlapping" and "enhanced" products ?

  - by pointlesspolitics

  Recently I attended a road show, organised by MS Gold Partner company in the UK. The products discussed were: SharePoint server (2010 and 2007), Exchange server, Office Communication Server 2007, Exchange hosted services Office Live meeting, Office Communicator, System Center Configuration Manager and Operation Manager, VMware, Windows 7 etc. As Microsoft claims the enhancement in the each product against higher version, I felt that clients are not much interested in all these details. For example Office Communicator, surely they have improved a lot the product and first site all said 'WOW' great product, but nobody wish to pay money for all these extra features. Some argued, they are bogged down by all these increased number of menus. They don't need soft call feature included with mobile call. It apply for all other products as well such as MS office (next what 2 ribbons ?), windows OS and many more. Indeed there must be good features in all these products, but is it worth to spend money and time to update the older system ? Also sometimes these feature will decrease the productivity instead increase it. *So do you think what ever enhancement MS is doing in the products is only for selling purpose, not a real use ?? and I think also keep the developer busy learning the new tools and features. * I am sure some some people here will argue that some people need this sort of features. But I am not talking about NASA or MI5 guys. I am talking of usual businesses and joe public. Any ideas welcome.

• How can I see which shared folders my program has access to?

  - by Kasper Hansen

  My program needs to read and write to folders on other machines that might be in another domain. So I used the System.Runtime.InteropServices to add shared folders. This worked fine when it was hard coded in the main menu of my windows service. But since then something went wrong and I don't know if it is a coding error or configuration error. What is the scope of a shared folder? If a thread in my program adds a shared folder, can the entire local machine see it? Is there a way to view what shared folders has been added? Or is there a way to see when a folder is added?

• Replace .sln with MSBuild and wrap contained projects into targets

  - by Filburt

  I'd like to create a MSBuild project that reflects the project dependencies in a solution and wraps the VS projects inside reusable targets. The problem I like solve doing this is to svn-export, build and deploy a specific assembly (and its dependencies) in an BizTalk application. My question is: How can I make the targets for svn-exporting, building and deploying reusable and also reuse the wrapped projects when they are built for different dependencies? I know it would be simpler to just build the solution and deploy only the assemblies needed but I'd like to reuse the targets as much as possible. The parts The project I like to deploy <Project DefaultTargets="Deploy" xmlns="http://schemas.microsoft.com/developer/msbuild/2003"> <PropertyGroup> <ExportRoot Condition="'$(Export)'==''">Export</ExportRoot> </PropertyGroup> <Target Name="Clean_Export"> <RemoveDir Directories="$(ExportRoot)\My.Project.Dir" /> </Target> <Target Name="Export_MyProject"> <Exec Command="svn export svn://xxx/trunk/Biztalk2009/MyProject.btproj --force" WorkingDirectory="$(ExportRoot)" /> </Target> <Target Name="Build_MyProject" DependsOnTargets="Export_MyProject"> <MSBuild Projects="$(ExportRoot)\My.Project.Dir\MyProject.btproj" Targets="Build" Properties="Configuration=Release"></MSBuild> </Target> <Target Name="Deploy_MyProject" DependsOnTargets="Build_MyProject"> <Exec Command="BTSTask AddResource -ApplicationName:CORE -Source:MyProject.dll" /> </Target> </Project> The projects it depends upon look almost exactly like this (other .btproj and .csproj).

• Calling method on category included from iPhone static library causes NSInvalidArgumentException

  - by Corey Floyd

  I have created a static library to house some of my code like categories. I have a category for UIViews in "UIView-Extensions.h" named Extensions. In this category I have a method called: - (void)fadeOutWithDelay:(CGFloat)delay duration:(CGFloat)duration; Calling this method works fine on the simulator on Debug configuration. However, if try to run the app on the device I get a NSInvalidArgumentException: [UIView fadeOutWithDelay:duration:]: unrecognized selector sent to instance 0x1912b0 *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[UIView fadeOutWithDelay:duration:]: unrecognized selector sent to instance 0x1912b0 It seems for some reason UIView-Extensions.h is not being included in the device builds. What I have checked/tried I did try to include another category for NSString, and had the same issue. Other files, like whole classes and functions work fine. It is an issue that only happens with categories. I did a clean all targets, which did not fix the problem. I checked the static library project, the categories are included in the target's "copy headers" and "compile sources" groups. The static library is included in the main projects "link binary with library" group. Another project I have added the static library to works just fine. I deleted and re-added the static library with no luck -ObjC linker flag is set Any ideas? nm output libFJSCodeDebug.a(UIView-Extensions.o): 000004d4 t -[UIView(Extensions) changeColor:withDelay:duration:] 00000000 t -[UIView(Extensions) fadeInWithDelay:duration:] 000000dc t -[UIView(Extensions) fadeOutWithDelay:duration:] 00000abc t -[UIView(Extensions) firstResponder] 000006b0 t -[UIView(Extensions) hasSubviewOfClass:] 00000870 t -[UIView(Extensions) hasSubviewOfClass:thatContainsPoint:] 000005cc t -[UIView(Extensions) rotate:] 000002d8 t -[UIView(Extensions) shrinkToSize:withDelay:duration:] 000001b8 t -[UIView(Extensions) translateToFrame:delay:duration:] U _CGAffineTransformRotate 000004a8 t _CGPointMake U _CGRectContainsPoint U _NSLog U _OBJC_CLASS_$_UIColor U _OBJC_CLASS_$_UIView U ___CFConstantStringClassReference U ___addsf3vfp U ___divdf3vfp U ___divsf3vfp U ___extendsfdf2vfp U ___muldf3vfp U ___truncdfsf2vfp U _objc_enumerationMutation U _objc_msgSend U _objc_msgSend_stret U dyld_stub_binding_helper

• should the builder reset its build environment after delivering the product

  - by Sudhi

  I am implementing a builder where in the deliverable is retrieved by calling Builder::getProduct() . The director asks various parts to build Builder::buildPartA() , Builder::buildPartB() etc. in order to completely build the product. My question is, once the product is delivered by the Builder by calling Builder::getProduct(), should it reset its environment (Builder::partA = NULL;, Builder::partB = NULL;) so that it is ready to build another product? (with same or different configuration?) I ask this as I am using PHP wherein the objects are by default passed by reference (nope, I don't want to clone them, as one of their field is a Resource) . However, even if you think from a language agnostic point of view, should the Builder reset its build environment ? If your answer is 'it depends on the case' what use cases would justify reseting the environment (and other way round) ? For the sake of providing code sample here's my Builder::gerProcessor() which shows what I mean by reseting the environment /** * @see IBuilder::getProessor() */ public function getProcessor() { if($this->_processor == NULL) { throw new LogicException('Processor not yet built!'); } else { $retval = $this->_processor; $this->_product = NULL, $this->_processor = NULL; } return $retval; }

• Keep Hibernate Initializer from Crashing Program

  - by manyxcxi

  I have a Java program using a basic Hibernate session factory. I had an issue with a hibernate hbm.xml mapping file and it crashed my program even though I had the getSessionFactory() call in a try catch try { session = SessionFactoryUtil.getSessionFactory().openStatelessSession(); session.beginTransaction(); rh = getRunHistoryEntry(session); if(rh == null) { throw new Exception("No run history information found in the database for run id " + runId_ + "!"); } } catch(Exception ex) { logger.error("Error initializing hibernate"); } It still manages to break out of this try/catch and crash the main thread. How do I keep it from doing this? The main issue is I have a bunch of cleanup commands that NEED to be run before the main thread shuts down and need to be able to guarantee that even after a failure it still cleans up and goes down somewhat gracefully. The session factory looks like this: public class SessionFactoryUtil { private static final SessionFactory sessionFactory; static { try { // Create the SessionFactory from hibernate.cfg.xml sessionFactory = new Configuration().configure().buildSessionFactory(); } catch (Throwable ex) { // Make sure you log the exception, as it might be swallowed System.err.println("Initial SessionFactory creation failed." + ex); throw new ExceptionInInitializerError(ex); } } public static SessionFactory getSessionFactory() { try { return sessionFactory; } catch(Exception ex) { return null; } } }

• generating and unmarshalling java classes while unmarshalling input contains a DTD

  - by Hans Westerbeek

  Hi, For a Spring-based project, I have the following situation to solve: I have XML files coming in whose contents I will have to parse at runtime. Those XML files come with a DTD reference. I need to generate the classes that the unmarshaller churns out using the right at build time, using the Maven2 plugin for the unmarshalling library of choice. This is also not very hard to do, once I have generated an XSD from the DTD. I want to use spring-oxm's UnMarshaller interface to do the unmarshalling at runtime. This I understand how to do. The xml files come in with a DTD reference, and all unmarshalling libraries out there want to do unmarshalling based on an XSD. Now, as described in the castor documentation, I can convert the DTD to an XSD and keep it on the classpath. However, when an actual XML file comes into the system it will still have that DTD reference at the top, and there's nothing I can really do about that (except for string replacing which feels hacky in this case). Will this cause the unmarshaller, like Castor to fail? Am I right in suspecting that this DTD reference will cause the unmarshalling to fail? Could I do pure DTD-based unmarshalling? Or can this somehow be prevented by providing detailed configuration to the unmarshaller? Until now, I have tried castor, xmlbeans and xstream. Which would fit my purposes best? Has anyone else been in this situation? Did you also end up just doing manual DOM or SAX parsing?

• How to format the Facebook news feed description of grouped app posts?

  - by JcFx

  I have an app which posts a message like this to a user's Facebook timeline: This is working fine, but if I post a few times, my posts get grouped on my news feed, and I get this: What settings should I use to control the way this news report appears? Instead of 'All about periods' and the page link in the box at the top, I'd like 'Body iQ Quiz' and the app description. Where would I set these values? And is it possible to make the grouped report say 'Jay cee Effex shared a link via Body iQ Quiz', the way the original post does? I'm posting from the Facebook AS3 API, and my post code looks like this: var auth:FacebookAuthResponse = Facebook.getAuthResponse(); var token:String = auth.accessToken; var user:String = auth.uid; var values:Object = { access_token: token, name: "Body iQ Quiz", picture: "http://a7.sphotos.ak.fbcdn.net/hphotos-ak-snc6/282950_427728213914009_630526316_n.jpg", link:"http://www.lil-lets.co.uk/en-GB/Wellbeing", description: "Women, how well do we know our bodies? Click here to find out what your Body iQ is.", message: result.FacebookBody + " " + result.FacebookTitle }; Facebook.api("/" + user + "/feed", handleSubmitFeed, values, URLRequestMethod.POST); ... but I'm not sure if this is something I can fix in code, or if the app configuration needs tweaking? NOTE: Some users report getting the latter format in their news feed even with a single post (I can't reproduce this), so perhaps grouping is a red herring, and the real question is how to format the news feed report of a timeline post?
