  • Axis2 and WSDL2Java: SOAP header is missing

    - by lasombra
    I've generated the java code from wsdl using WSDL2Java. I create a SOAP requestand I send it to the server, which answers with an AxisFault. If I have a look in the soap request there is now header tag . Why not? Does the follwing line in the stub not add a header? // adding SOAP soap_headers _serviceClient.addHeadersToEnvelope(env); What would be the solution to add a header, so that the SOAP request looks like that: <?xml version='1.0' encoding='UTF-8'?> <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"> <soapenv:Header/> <soapenv:Body> ... </soapenv:Body> </soapenv:Envelope>

  • Ruby Programming Techniques: simple yet not so simple object manipulation

    - by Shyam
    Hi, I want to create an object, let's say a Pie. class Pie def initialize(name, flavor) @name = name @flavor = flavor end end But a Pie can be divided in 8 pieces, a half or just a whole Pie. For the sake of argument, I would like to know how I could give each Pie object a price per 1/8, 1/4 or per whole. I could do this by doing: class Pie def initialize(name, flavor, price_all, price_half, price_piece) @name = name @flavor = flavor @price_all = price_all @price_half = price_half @price_piece = price_piece end end But now, if I would create fifteen Pie objects, and I would take out randomly some pieces somewhere by using a method such as getPieceOfPie(pie_name) How would I be able to generate the value of all the available pies that are whole and the remaining pieces? Eventually using a method such as: myCurrentInventoryHas(pie_name) # output: 2 whole strawberry pies and 7 pieces. I know, I am a Ruby nuby. Thank you for your answers, comments and help!

  • Does Blogging affect Job Prospects?

    - by BM
    Would a hiring manager at a small-to-medium consulting firm/corporation consider active blogging by a candidate about Programming/software/technology as a positive? Should the candidate disclose this information during the interviews or put it on the resume? Thanks for the answers, So far the views about this topic has been.. Don't mention the blog if it is not relevant to the job. Mention the blog, if you believe your blog has quality content. Potential risk of not being accepted by culture of the employer's workplace. Could be a valuable for consultants to publish & preview their skills and experience. Certain Employers may consider blogging of a candidate a plus. Be careful what you post on the blog,no badmouthing,rants and overt criticism of others. Do not lie about blogging,if directly asked during the interview.

  • What should a Java/SOA developer be able to do?

    - by Regular Joe
    Hello community. I got assigned the task to list the activities a Java Developer should be able to perform and create an estimate about the time it would take. I've came up with the following: S = Small complexity M = Medium complexity H = High complexity 1d = 1 day Create JDBC CRUD backend ( S=1d, M=5d, H=10d ) Create JSP/Servlet frontend for a CRUD app ( S=1d, M=10d, H=20d ) Create Swing desktop frontend ( S=1d, M=15d, H=30d) Create ORM based CRUD ... Create Webapp fronend with webframework ... This is thought for a Java "enterprise" developer. The other profile I have is SOA Developer, but I could not pass beyond: Create webservice ( S=.5d, M=2d, H=7d ) Q.- What other activities should a Java Developer be able to do? Q.- What activities should a SOA Developer be able to do? Please, help me with this, I know this is in the limit of the kind of questions that could be asked here, but I really need a little push on this, and I don't want to go to Yahoo Answers for this.

  • Extracting CDATA Using jQuery

    - by George L Smyth
    It looks like this has been asked before, but the answers do not appear to work for me. I am outputting information from a local XML file, but the description elements is not being output because it is enclosed in CDATA - if I remove the CDATA portion then things work fine. Here is my code: $(document).ready( function() { $.get('test.xml', function($info) { objInfo = $($info); objInfo.find('item').slice(0,5).each( function() { var Guid = $(this).find('guid').text(); var Title = $(this).find('title').text(); var Description = $(this).find('description').text(); $('#Content').append( "<p><a href='" + Guid + "'>" + Title + "</a>&nbsp;" + Description + "</p>" ) } ); }, 'xml' ); } ) Any idea how I can successfully extract Description information that is wrapped in CDATA? Thanks - george

  • CSS inheritance: applying selector for itself and every descendant

    - by Cawas
    Get a custom user CSS and type this .answered-accepted { color: white !important; background: #090 !important; } Now go to answers.unity3d and look for an accepted answer. The design looks bad, because the <strong> in there overrides the customization. The fix I've found is this: .answered-accepted, .answered-accepted * { color: white !important; background: #090 !important; } Now it looks fine on the website, but the code looks ugly!! How can I do this without repeating the class name?

  • Where do you get ArcGIS development questions answered?

    - by nw
    Where do you have the most success getting your ArcGIS development questions answered? ESRI forums? Stack Overflow? Google? Mailing lists? Blog posts? ESRI documentation? I can usually get answers to my ASP.NET/Oracle/JavaScript/C# questions in short order, but questions about ESRI products and APIs are a different matter. Posts founder in the forums, Google returns void, etc. I'm sure this is not uncommon for niche commercial products, but frustrating nevertheless. What works for you? Please share.

  • Powershell 2.0 Hang When Run From MsDeploy pre- post- ops using c/

    - by SonOfNun
    I am trying to invoke powershell during the preSync call in a MSDeploy command, but powershell does not exit the process after it has been called. The command (from command line): "tools/MSDeploy/msdeploy.exe" -verb:sync -preSync:runCommand="powershell.exe -NoLogo -NoProfile -NonInteractive -ExecutionPolicy Unrestricted -Command C:/MyInstallPath/deploy.ps1 Set-WebAppOffline Uninstall-Service ",waitInterval=60000 -usechecksum -source:dirPath="build/for-deployment" -dest:wmsvc=BLUEPRINT-X86,username=deployer,password=deployer,dirPath=C:/MyInstallPath I used a hack here (http://therightstuff.de/2010/02/06/How-We-Practice-Continuous-Integration-And-Deployment-With-MSDeploy.aspx) that gets the powershell process and kills it but that didn't work. I also tried taskkill and the sysinternals equivalent, but nothing will kill the process so that MSDeploy errors out. The command is executed, but then just sits there. Any ideas what might be causing powershell to hang like this? I have found a few other similar issues around the web but no answers.

  • Python: Slicing a list into n nearly-equal-length partitions

    - by Drew
    I'm looking for a fast, clean, pythonic way to divide a list into exactly n nearly-equal partitions. partition([1,2,3,4,5],5)->[[1],[2],[3],[4],[5]] partition([1,2,3,4,5],2)->[[1,2],[3,4,5]] (or [[1,2,3],[4,5]]) partition([1,2,3,4,5],3)->[[1,2],[3,4],[5]] (there are other ways to slice this one too) There are several answers in here http://stackoverflow.com/questions/1335392/iteration-over-list-slices that run very close to what I want, except they are focused on the size of the list, and I care about the number of the lists (some of them also pad with None). These are trivially converted, obviously, but I'm looking for a best practice. Similarly, people have pointed out great solutions here http://stackoverflow.com/questions/312443/how-do-you-split-a-list-into-evenly-sized-chunks-in-python for a very similar problem, but I'm more interested in the number of partitions than the specific size, as long as it's within 1. Again, this is trivially convertible, but I'm looking for a best practice.

  • Why are access modifiers on web service proxy methods important

    - by cand
    I'm creating interface to an external web service with C# client generated from WSDL. And in this client class I have methods with signature like: public ResponseType InvokeMethod(RequestType request). I want to change its access modifier to protected, but then web service responds with "web service method name is not valid" exception. Do You know why is that so? I understand that maintaining method name can be important for some reasons, but why can't I change this access modifier? Shouldn't it be a matter of my code what access I want to give to this method? Thanks for all the answers in advance.

  • SumProduct over sets of cells (not contiguous)

    - by Craig
    I have a total data set that is for 4 different groupings. One of the values is the average time, the other is count. For the Total I have to multiply these and then divide by the total of the count. Currently I use: =SUM(D32*D2,D94*D64,D156*D126,D218*D188)/SUM(D32,D94,D156,D218) I would rather use a SumProduct if I can to make it more readable. I tried to do: =SUMPRODUCT((D2,D64,D126,D188),(D32,D94,D156,D218))/SUM(D32,94,D156,D218) But as you can tell by my posting here, that did not work. Is there a way to do SumProduct like I want? Thoughts, Answers, Questions, Comments? Craig

  • [WPF C#]Get UserControl or VisualTree in DataValidation of TextBlock

    - by dalind
    Hy, I have a validator set on the text property of a textblock. For a correct validation I would need the parent usercontrol of the textblock, but the only things I have in the validator are the value object (a string) and the culture (doesn't help either). Does anyone know a way to get certain usercontrols in a class/a method where I have no access to any kind of visual or control of my application. The problem could be solve if I could give the validator the usercontrol or the textblock as parameters, but I didn't find a way to do so.. Thank you very much for your answers. Greets

  • |Ideas for applications using face detection and recognition

    - by Omry
    Full disclosure: I work at face.com. Face.com just launched a free (up to an hourly limit) face detection and recognition REST API. We got a very handy API sandbox that developers can use to play the API and to see what it can and can't do. Besides the obvious point of letting you guys know about the API, I wanted to hear from you what kind of applications you think can be developed with it. Some pretty obvious ideas: Face based login (not entirely secure but still fun). Automatic face crop for sites that let users upload photos (dating sites etc) Some kind of integration into augmented reality games There is no right or wrong answers here, use your imagination :).

  • Automatically call httpservice.send

    - by Matt Robinson
    I have an application that displays the data from 3 xml files (auto generated from SQL table) using httpservices to get them. The first xml file is small and contains around 30 items, the second and thrid contain around 200-300 items each. The first dataset loads quickly and is invoked on creationComplete. The second and third are called from click events and take quite a few seconds to load. A user of the application will take at least 2-3 minutes reading the data from the first dataset so is there a way I can have the httpservice.send for the second and third xml files called automatically, straight after the first file has finished loading to be able to show the first dataset immediateley and get rid of the waiting times between dataset views. An answer doesnt need to be specific, just a point in the right direction would be great. All answers greatly appreciated Matt

  • Best practices for large solutions in Visual Studio (2008)

    - by Eyvind
    We have a solution with around 100+ projects, most of them C#. Naturally, it takes a long time to both open and build, so I am looking for best practices for such beasts. Along the lines of questions I am hoping to get answers to, are: how do you best handle references between projects should "copy local" be on or off? should every project build to its own folder, or should they all build to the same output folder(they are all part of the same application) are solutions folders a good way of organizing stuff? I know that splitting the solution up into multiple smaller solutions is an option, but that comes with its own set of refactoring and building headaches, so perhaps we can save that for a separate thread :-)

  • What is a robust jQuery Rich Text Editor with image upload capabilities?

    - by thinkswan
    I know this question has been asked countless times, but answers are mixed, so I thought I'd test the waters and see what the latest verdict is out in the development community. I need a [preferably jQuery] rich text editor plugin that simply attaches itself to <textarea> elements and supports image uploads. It doesn't need to be too advanced. Just alignment, bold, italic, styles and image support. I tried CKEditor (along with CKFinder for image uploads), but it just has too many features and is too heavy for what I need. This is going to be used for simple webpage editing.

  • COMPLETE list of HTML tag attributes which have a URL value?

    - by system PAUSE
    Besides the following, are there any HTML tag attributes that have a URL as their value? href attribute on tags: <link>, <a>, <area> src attribute on tags: <img>, <iframe>, <frame>, <embed>, <script>, <input> action attribute on tags: <form> data attribute on tags: <object> Looking for tags in wide usage, including non-standard tags and old browsers as well as HTML 4.01, HTML 5, and XHTML. Yes this question is kinda lightweight, but I googled around for about 45 minutes and didn't find this data centralized anywhere, so I figure it might help some other developer to have it here. Plus I'm sure I'm missing something. Feel free to repeat/reorganize this list in your answer. Upvoting the most complete answers will probably be most helpful to others.

  • How are lists implemented in Haskell (GHC)?

    - by eman
    I was just curious about some exact implementation details of lists in Haskell (GHC-specific answers are fine)--are they naive linked lists, or do they have any special optimizations? More specifically: Do length and (!!) (for instance) have to iterate through the list? If so, are their values cached in any way (i.e., if I call length twice, will it have to iterate both times)? Does access to the back of the list involve iterating through the whole list? Are infinite lists and list comprehensions memoized? (i.e., for fib = 1:1:zipWith (+) fib (tail fib), will each value be computed recursively, or will it rely on the previous computed value?) Any other interesting implementation details would be much appreciated. Thanks in advance!

  • sqlite on iphone can open db but not prepare statements

    - by jan
    I'm brand new to using sqlite so I may have missed something basic. I've created a database and copied it into my app's document's directory. I'm able to open it but when I make a call to sqlite3_prepare_v2 I receive SQLITE_ERROR, "SQL error or missing database". here's my code: sqlite3 *database; if(sqlite3_open([dbPath UTF8String], &database) == SQLITE_OK) { sqlite3_stmt *compiledStatement; NSString *sqlStatement = @"select * from dbname"; int result = sqlite3_prepare_v2(database, [sqlStatement UTF8String], -1, &compiledStatement, nil); ... } the same sql statement works in the terminal. I've found this question in a few places either without answers or with solutions that don't fix my problem. I'm hoping someone here will be able to help. Thanks.

  • Comparison of Code Review Tools/Systems

    - by SytS
    There are a number of tools/systems available aimed at streamlining and enhancing the code review process, including: CodeStriker Review Board, code review system in use at VMWare Code Collaborator, commercial product by SmartBear Rietveld, based on Modrian, the code review system in use at Google Crucible, commercial product by Atlassian These systems all have varying feature sets, and differ in degrees of maturity and polish; the selection is a little bewildering for someone who is evaluating code review systems for the frist time. Some of these tools have already been mentioned in other questions/answers on StackOverflow, but I would like to see a more comprehensive comparison of the more popular systems, especially with respect to: integration with source control systems integration with bug tracking systems supported workflow (reviews pre/post commit, review or contiguous/non-contigous revision ranges, etc) deployment/maintenance requirements

  • R heatmaps - non-text labels?

    - by Carl
    I am making a heatmap plot; currently the axes are labeled by index number. However, the index number corresponds to a series of 1/0s, which my group typically represents with a row of filled(1) or unfilled(0) boxes (think chessboard, though not strictly alternating colors). I'd like to use that representation instead of the index numbers. Any suggestions? I've considered simply making the labels as a plot, and positioning that adjacent to the heatmap, but I'm not finding a convenient way to do that either. I will also appreciate answers that are more generically applicable. edit - current code: map <- data.matrix(read.csv("./heatmap.out", header=F, sep=" ")) # ...some clean-up p<-heatmap(map, Rowv=NA, Colv=NA, col=grey(10:0 / 10)) this simply labels the heatmap rows/cols by index number. heatmap.out is raw numeric data.

  • Best practices book for CRUD apps

    - by Kevin L.
    We will soon be designing a new tool to calculate commissions across multiple business units. This new compensation scheme is pretty clever and well thought-out, but the complexity that the implementation will involve will make the Hubble look like a toaster. A significant portion of the programming industry involves CRUD apps; updating insurance data, calculating commissions (Joel included) ...even storing questions and answers for a programmer Q&A site. We as programmers have Code Complete for the low-level formatting/style and Design Patterns for high-level architecture (to name just a few). Where’s the comparable book that teaches best practices for CRUD?

  • How to get users to read error messages?

    - by FX
    If you program for a nontechnical audience, you find yourself at a high risk that users will not read your carefully worded and enlightening error messages, but just click on the first button available with a shrug of frustration. So, I'm wondering what good practices you can recommend to help users actually read your error message, instead of simply waiving it aside. Ideas I can think of would fall along the lines of: Formatting of course help; maybe a simple, short message, with a "learn more" button that leads to the longer, more detailed error message Have all error messages link to some section of the user guide (somewhat difficult to achieve) Just don't issue error messages, simply refuse to perform the task (a somewhat "Apple" way of handling user input) Edit: the audience I have in mind is a rather broad user base that doesn't use the software too often and is not captive (i.e., not an in-house software or narrow community). A more generic form of this question was asked on slashdot, so you may want to check there for some of the answers.

  • Why is thread local storage so slow?

    - by dsimcha
    I'm working on a custom mark-release style memory allocator for the D programming language that works by allocating from thread-local regions. It seems that the thread local storage bottleneck is causing a huge (~50%) slowdown in allocating memory from these regions compared to an otherwise identical single threaded version of the code, even after designing my code to have only one TLS lookup per allocation/deallocation. This is based on allocating/freeing memory a large number of times in a loop, and I'm trying to figure out if it's an artifact of my benchmarking method. My understanding is that thread local storage should basically just involve accessing something through an extra layer of indirection, similar to accessing a variable via a pointer. Is this incorrect? How much overhead does thread-local storage typically have? Note: Although I mention D, I'm also interested in general answers that aren't specific to D, since D's implementation of thread-local storage will likely improve if it is slower than the best implementations.
