  • Why am I getting org.xml.sax.SAXException for this block of XML?

    - by drachenstern
    I've anonymised a bit of this. Hopefully it doesn't detract from the useful message. stringARRAY is where I think I'm getting thrown at, but I'm not sure, so if I'm looking at the wrong place, lemme know. From the WSDL <xsd:element name="LongishOpName"> <xsd:complexType> <xsd:sequence> <xsd:element maxOccurs="unbounded" name="stringARRAY" type="xsd:string" /> <xsd:element name="stringfield1" type="xsd:string" /> <xsd:element name="stringfield2" type="xsd:string" /> </xsd:sequence> </xsd:complexType> </xsd:element> Actual method call looks like this: string originalValue = "some useful value"; string[] usefulName1 = new[] { originalValue }; service.response[] responses = server.LongishOpName( usefulName1, someString1, someString2 ); And it generates this XML to the server (Thanks to Fiddler2): <?xml version="1.0" encoding="utf-8"?> <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <soap:Body> <LongishOpName xmlns="http://appropriate-namespace"> <stringARRAY>114003</stringARRAY> <stringfield1>a string</stringfield1> <stringfield2>a string</stringfield2> </LongishOpName> </soap:Body> </soap:Envelope> To which I get this response <?xml version="1.0" encoding="utf-8"?> <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <soapenv:Body> <soapenv:Fault> <faultcode>soapenv:Server.userException</faultcode> <faultstring>org.xml.sax.SAXException: Found character data inside an array element while deserializing</faultstring> <detail> <ns1:hostname xmlns:ns1="http://xml.apache.org/axis/">SERVERNAME</ns1:hostname> </detail> </soapenv:Fault> </soapenv:Body> </soapenv:Envelope> Is my soap message actually coming out malformed? (yes I am using the ASP.NET web references to do all the lifting, I'm not generating by hand) Should I be doing something different? Do I just need to go home and sleep on it and tomorrow everything will "just work"?

  • What is a monad?

    - by kronoz
    Having briefly looked at Haskell recently I wondered whether anybody could give a brief, succinct, practical explanation as to what a monad essentially is? I have found most explanations I've come across to be fairly inaccessible and lacking in practical detail, so could somebody here help me?

  • SplitView Controller portrait mode- Top button keeps shifting to right.

    - by nishantcm
    Hi, I am using SplitViewController in ipad. On a button click from detail view, I open a modalview which is in full screen mode. Whenever I dismiss the modal view, the button which displays the table view in portrait mode shifts to the right. If I continue the process of opening the modal view and dismissing it, it keeps moving to the right until it disappears to the right of the screen. Any idea why this is happening?

  • Pushing from an existing git repo to a new SVN repo

    - by Drew Noakes
    All examples I've found on git-svn detail how to use git to mirror an existing SVN repo, work on it, then commit your changes back. I have a pure git repo, created via git init not git-svn init and want to commit it to a new SVN service (Google Code, to be specific). Is this something that can be done?

  • How do I move from being a software developer to being a software architect?

    - by Nestor
    I mean... Should I start programming less and designing more? Should I stop reading programming books, and start reading more books about pattern designs, etc? Should I stop focusing primarily on Microsoft technologies and open up my horizons with other technologies (in order to get a broader perspective)? How should I change my mind set in general (perhaps less detail oriented) ? etc I'm looking for concrete advice, especially from your own experience!

  • Size of split views in UISplitViewController? No hard-coded values please...

    - by Steve
    Hey, I'm building view hierarchies programmatically, without using a nib, for the master and the detail views in the UISplitViewController. My problem is that I do not know how large those views are. Well, of course, I know their hard-coded values... But I want to be a good citizen and not use hard-coded values and instead query them. Problem is that I have no idea how... Do you? Thanks in advance, /Steve

  • Finding leaks under GeneralBlock-16?

    - by erastusnjuki
    If ObjectAlloc cannot deduce type information for the block, it uses 'GeneralBlock'. Any strategies to get leaks from this block that may eliminate the need of my 'trial and error' methods that I use? The Extended Detail thing doesn't really do it for me as I just keep guessing.

  • Sibling UIViewController Navigation

    - by Joo Park
    would anybody care to comment on this piece of code? It allows you to do "prev" or "next" once in the detail view of a uiviewcontroller. So, if you have 4 uiviewcontrollers, you can navigate from #3 to #2 with previous or #3 to #4 with next. It works, but, my question is, is this the best way to implement this? or, is there a better way. http://github.com/joop23/UIViewController

  • Future proof Tweeting with PHP

    - by YsoL8
    Hello I'm looking to implement a system for tweeting directly from my site backend, which is written in PHP 5. I have a script from the internet that I can adapt, but I'm concerned that when Twitter switches to Oauth only, I'll be out in the cold. Basically, I'm hoping someone can point me toward a script/tutorial that will let me do the following: access twitter via the Oauth system Post Tweets and receive error codes Let me define an application/site name (I'm a bit fuzzy on whether Twitter allows this) Ideally I need all 3 points explained in detail. Thanks
