  • Why wouldn't a flex remoteobject be able to work within a custom component?

    - by Gary
    Please enlighten this flex noob. I have a remoteobject within my main.mxml. I can call a function on the service from an init() function on my main.mxml, and my java debugger triggers a breakpoint. When I move the remoteobject declaration and function call into a custom component (that is declared within main.mxml), the remote function on java-side no longer gets called, no breakpoints triggered, no errors, silence. How could this be? No spelling errors, or anything like that. What can I do to figure it out? mxml code: < mx:RemoteObject id="myService" destination="remoteService" endpoint="$(Application.application.home}/messagebroker/amf" > < /mx:RemoteObject > function call is just 'myService.getlist();' when I move it to a custom component, I import mx.core.Application; so the compiler doesn't yell my child component: child.mxml <mx:Panel xmlns:mx="http://www.adobe.com/2006/mxml" creationComplete="init()" > <mx:Script> <![CDATA[ import mx.core.Application; public function init():void { helloWorld.sayHello(); } ]]> </mx:Script> <mx:RemoteObject id="helloWorld" destination="helloService" endpoint="$(Application.application.home}/messagebroker/amf" /> <mx:Label text="{helloWorld.sayHello.lastResult}" /> </mx:Panel> my main.mxml: <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" creationComplete="init()" xmlns:test="main.flex.*" > <mx:Script> <![CDATA[ [Bindable] public var home:String; [Bindable] public var uName:String; public function init():void { //passed in by wrapper html home = Application.application.parameters.appHome; uName = Application.application.parameters.uName; } ]]> </mx:Script> <test:child /> </mx:Application>

  • Question about functional OOP style in JavaScript

    - by valums
    I prefer to use functional OOP style for my code (similar to the module pattern) because it helps me to avoid the "new" keyword and all problems with the scope of "this" keyword in callbacks. But I've run into a few minor issues with it. I would like to use the following code to create a class. namespace.myClass = function(){ var self = {}, somePrivateVar1; // initialization code that would call // private or public methods privateMethod(); self.publicMethod(); // sorry, error here function privateMethod(){} self.publicMethod = function(){}; return self; } The problem is that I can't call public methods from my initialization code, as these functions are not defined yet. The obvious solution would be to create an init method, and call it before "return self" line. But maybe you know a more elegant solution? Also, how do you usually handle inheritance with this pattern? I use the following code, butI would like to hear your ideas and suggestions. namespace.myClass2 = function(){ var self = namespace.parentClass(), somePrivateVar1; var superMethod = self.someMethod; self.someMethod = function(){ // example shows how to overwrite parent methods superMethod(); }; return self; } Edit. For those who asked what are the reasons for choosing this style of OOP, you can look into following questions: http://stackoverflow.com/questions/1557386/prototypal-vs-functional-oop-in-javascript http://stackoverflow.com/questions/383402/is-javascript-s-new-keyword-considered-harmful

  • Is there a way to unit test an async method?

    - by Jiho Han
    I am using Xunit and NMock on .NET platform. I am testing a presentation model where a method is asynchronous. The method creates an async task and executes it so the method returns immediately and the state I need to check aren't ready yet. I can set a flag upon finish without modifying the SUT but that would mean I would have to keep checking the flag in a while loop for example, with perhaps timeout. What are my options?

  • Please explain JSONP

    - by Cheeso
    I don't understand jsonp. I understand JSON. I don't understand JSONP. Wikipedia is the top search result for JSONP. It says JSONP or "JSON with padding" is a JSON extension wherein a prefix is specified as an input argument of the call itself. Huh? What call? That doesn't make any sense to me. JSON is a data format. There's no call. The 2nd search result is from some guy named Remy, who writes JSONP is script tag injection, passing the response from the server in to a user specified function. I can sort of understand that, but it's still not making any sense. What is JSONP, why was it created (what problem does it solve), and why would I use it? Addendum: I've updated Wikipedia with a clearer and more thorough description of JSONP, based on jvenema's answer. Thanks, all.

  • Using jQuery and AJAX works for all functions except one, really bizarre issue (from my perspective)

    - by CoreyT
    I am working on a classic asp form that has a number of dropdowns. Three of these are cascading, i.e. they rely in the previous dropdown. For almost everything this code works fine, one of them however is not playing nice. To start off I have a script tag with the following in it: $(document).ready(function () { $("#AcademicLevel").change(getList); $("#CourseDeliveryTime").change(updateLocation); $("#ProgramType").change(updateEntryTerm); }); This works just fine for the first two elements of the form, AcademicLevel and CourseDeliveryTime, the third however does not take effect however. If I use Firebug's Console and run that same line of code, $("#ProgramType").change(updateEntryTerm);, it starts to work, sort of. What happens is what confuses me. If the function it is pointing to, updateEntryTerm, has an alert() call in it, it works. If the alert is commented out, it does not work. The function is below: function updateEntryTerm() { $.ajax({ type: "POST", url: "../Classic ASP and AJAX/jQueryExample.asp", dataType: "application/x-www-form-urlencoded", data: "Action=UpdateEntryTerm&acadLevel=" + $("#AcademicLevel").val() + "&courseTime=" + $("#CourseDeliveryTime").val() + "&programType=" + $("#ProgramType").val(), async: false, success: function (msg) { $("#EntryTerm").remove(); $("#tdEntryTerm").append(msg); //alert(msg); } //, //error: function (xhr, option, err) { // alert("XHR Status: " + xhr.statusText + ", Error - " + err); //} }); } I am lost on two different issues here, First why is the call to $("#ProgramType").change(updateEntryTerm); not working unless I run it in Firebug Console? Second, why does the function itself, updateEntryTerm, not work unless the alert() call is present? Has anyone seem something like this before?

  • Strange activity stack behavior when using MapActivity

    - by AndroidDev
    I have the following activity structure in my application A simple "splash screen" activity is started when the application is fired up (let's call it "Splash"). This activity starts the main activity when the user presses a button (I will call it "Main"). Main can in turn start two activities from the menu. The first activity presents a simple form (let's call this one "Form"), the second is a MapActivity that presents a map (it is called "Map"). Main, Form, and Map are declared exactly the same in the manifest: <activity android:name="fully qualified activity class" android:screenOrientation="landscape" android:configChanges="keyboard|keyboardHidden|orientation" > <intent-filter> <action android:name="android.intent.action.DEFAULT" /> <category android:name="android.intent.category.DEFAULT" /> </intent-filter> </activity> When Main is active and I start Form and press "back", Main comes up again. Pressing "back" again brings up "Splash". Nothing strange here. Now comes the strange part: when I am in Main, start Map, and press "back", Main comes up as expected. But pressing "back" again just restarts Main. A second press on "back" is needed to bring me back to Splash! So it seems that starting the Map activity somehow results in Main ending up on the activity stack twice while starting the Form activity does not! Both Form and Map are started like this: startActivity(new Intent(this, MyActivity.class)); I don not catch the back key in any activity. Any clues on what is going on or how to debug this?

  • NHibernate with nothing but stored procedures

    - by ChrisB2010
    I'd like to have NHibernate call a stored procedure when ISession.Get is called to fetch an entity by its key instead of using dynamic SQL. We have been using NHibernate and allowing it to generate our SQL for queries and inserts/updates/deletes, but now may have to deploy our application to an environment that requires us to use stored procedures for all database access. We can use sql-insert, sql-update, and sql-delete in our .hbm.xml mapping files for inserts/updates/deletes. Our hql and criteria queries will have to be replaced with stored procedure calls. However, I have not figured out how to force NHibernate to use a custom stored procedure to fetch an entity by its key. I still want to be able to call ISession.Get, as in: using (ISession session = MySessionFactory.OpenSession()) { return session.Get<Customer>(customerId); } and also lazy load objects, but I want NHibernate to call my "GetCustomerById" stored procedure instead of generating the dynamic SQL. Can this be done? Perhaps NHibernate is no longer a fit given this new environment we must support.

  • In Perl, how can a subroutine get a coderef that points to itself?

    - by hillu
    For learning purposes, I am toying around with the idea of building event-driven programs in Perl and noticed that it might be nice if a subroutine that was registered as an event handler could, on failure, just schedule another call to itself for a later time. So far, I have come up with something like this: my $cb; my $try = 3; $cb = sub { my $rc = do_stuff(); if (!$rc && --$try) { schedule_event($cb, 10); # schedule $cb to be called in 10 seconds } else { do_other_stuff; } }; schedule_event($cb, 0); # schedule initial call to $cb to be performed ASAP Is there a way that code inside the sub can access the coderef to that sub so I could do without using an extra variable? I'd like to schedule the initial call like this. schedule_event( sub { ... }, 0); I first thought of using caller(0)[3], but this only gives me a function name, (__ANON__ if there's no name), not a code reference that has a pad attached to it.

  • After Navigate2 Method returns S_OK Stuck at READYSTATE of READYSTATE_LOADING

    - by Stone Free
    I am working on a MFC Document View architecture application which has multiple documents and views and a tabbed window interface. I have been tasked with making an automatic switch to another tab on the press of the OK button in one of the other tabs. When the other tab is clicked on it uses a C++ wrapper over IWebBrowser2 to navigate to a specific web page. When this is done manually by clicking on the tab everything is fine and the webpage within the view loads successfully. In my first attempt at doing this the tab successfully switched in response to a call to AfxGetMainWnd()->SendMessageToDescendants(SOME_MESSAGE, ...); however by sending this windows message at the wrong point the application would crash once control returned because the chain of events caused the (modeless) dialog (*) that sent the message, to no longer exist. I then found the correct place to make the call, but now when the other tab is activated, it no longer displays the webpage as it should. To debug this problem I added code to check the READYSTATE in both the situation where it works and the situation where it does not. When the page fails to load (despite the call to Navigate2 returning S_OK), the READYSTATE just stays at READYSTATE_LOADING. Unfortunately now I am to many edits away from when I had it partially working. I have added TRACE statements to the most obvious events such as OnSetFocus, CView::OnActivateView but all traces come out in the same order despite the behaviour being different * hosted in the view

  • Are local variables in Fortran 77 static or stack dynamic?

    - by mm2887
    For my programming languages class one hw problem asks: Are local variables in FORTRAN static or stack dynamic? Are local variables that are INITIALIZED to a default value static or stack dynamic? Show me some code with an explanation to back up your answer. Hint: The easiest way to check this is to have your program test the history sensitivity of a subprogram. Look at what happens when you initialize the local variable to a value and when you don’t. You may need to call more than one subprogram to lock in your answer with confidence. I wrote a few subroutines: - create a variable - print the variable - initialize the variable to a value - print the variable again Each successive call to the subroutine prints out the same random value for the variable when it is uninitialized and then it prints out the initialized value. What is this random value when the variable is uninitialized? Does this mean Fortran uses the same memory location for each call to the subroutine or it dynamically creates space and initializes the variable randomly? My second subroutine also creates a variable, but then calls the first subroutine. The result is the same except the random number printed of the uninitialized variable is different. I am very confused. Please help! Thank you so much.

  • using jquery (json) to get ajax database entries in wordpress - PHP not working

    - by Matt Facer
    I'm writing a plugin for my wordpress site and am having trouble understanding the jquery ajax requests. In a nutshell, I am trying to get some user meta data loaded when the page loads. So in my javascript file I have a line: $.getJSON("http://mysite.co.uk/wp-content/plugins/myplugin/ajax/ajax.php?action=test", function(json) { // do stuff }); So the above DOES get called, but it's the PHP code I'm having trouble with. In the file ajax.php, I am making a database call, but NONE of the usual class information is available. I've tried including the admin ajax page, various other pages from my own plugin (which does work).... not sure what else to do! The database call method works OK in my plugin code.. but I guess that the ajax.php file is outside the WP framework so that's why it's not working... but I don't know how to get it IN the framework!? I just need to use the $wpdb->get_results($sql); command to get my SQL. The error returned from firebug is that I am making a call to an undefined function. Thanks for any help... $.getJSON("http://www.offbeatattractions.co.uk/wp-content/plugins/wp-geo-extended/ajax/change_location.php?action=listpoints", function(json) { alert(json.Locations.length);

  • How do i transfer this unmanaged code from asp to asp.net 2/mvc?

    - by melaos
    hi guys, i'm a newbie to ASP.net interop features, so what i have right here is some unmanaged dll that i need to call from my asp.net mvc app. the dll name is CTSerialNumChecksum.dll set CheckSumObj = Server.CreateObject("CTSerialNumChecksum.CRC32API") validSno = CheckSumObj.ValidateSerialNumber(no) i know it's unmanaged because when i try to add reference to the dll it doesn't work. i try to follow some tutorials on interop and marshalling but thus far i wasn't able to get the code to work. i'm trying to wrap the object into another static class and just let the rest of the app to call the code. using System; using System.Runtime.InteropServices; namespace OnlineRegisteration.Models { public static class SerialNumberChecksum { [DllImport("CTSerialNumChecksum")] public static extern int ValidateSerialNumber(string serialNo); } } Questions: How do i write the class? And what tool can i use to identify what type of dll a particular file is, i.e. unmanaged c++, etc? Also i intend to make use jquery to do ajax call later so i can use this to validate my form pre-submission. Is there a better way to handle this?

  • Detecting death of spawned process using Window CRT

    - by Michael Tiller
    Executive summary: I need a way to determine whether a Windows process I've spawned via _spawnl and am communicating with using FDs from _pipe has died. Details: I'm using the low-level CRT function in Windows (_eof, _read) to communicate with a process that was spawned via a call to _spawnl (with the P_NOWAIT) flag. I'm using _pipe to create file descriptors to communicate with this spawned process and passing those descriptors (the FD #) to it on the command line. It is worth mentioning that I don't control the spawned process. It's a black box to me. It turns out that the process we are spawning occasionally crashes. I'm trying to make my code robust to this by detecting the crash. Unfortunately, I can't see a way to do this. It seems reasonable to me to expect that a call to _eof or _read on one of those descriptors would return an error status (-1) if the process had died. Unfortunately, that isn't the case. It appears that the descriptors have a life of their own independent of the spawned process. So even though the process on the other end is dead, I get no error status on the file descriptor I'm using to communicate with it. I've got the PID for the nested process (returned from the _spanwnl call) but I don't see anything I can do with that. My code works really well except for one thing. I can't detect whether the spawned process is simply busy computing me an answer or has died. If I can use the information from _pipe and _spawnl to determine if the spawned process is dead, I'll be golden. Suggestions very welcome. Thanks in advance. UPDATE: I found a fairly simple solution and added it as the selected answer.

  • Android SQLite database locale, locking, and version

    - by gdoten
    In some books and online I see these method calls being made after a database is created: db.setLocale(Locale.getDefault()); db.setLockingEnabled(true); db.setVersion(DB_VERSION); Why is this done? As far as I can tell, after creating a new database, the system adds a table named android_metadata with one field named locale and that table has one row with the locale field set to "en_US". Now I assume the column has that value because I am using a U.S. phone, and if I were using a phone from a different region then the locale field would be set appropriately. Can anyone confirm this? I'm guessing that the setLocale method would only be useful in the case that you install a pre-built database onto a phone and then want to change the locale to match the phone's locale. Sound right? The documentation for setLockingEnabled says it defaults to true so there's no need to make that call, right? Lastly, what's with the call to setVersion? I can't find a table that contains this information so I've been assuming that the database file itself stores the version number somewhere. So when I create a database, which requires you to have already specified the version number in the call to the SQLiteOpenHelper constructor, there's no point in calling setVersion. Again, perhaps this method exists for the case of installing a pre-built database to a device and you then wish to change the database's version (though I can't think of when doing this would make sense). Thanks for any insight!

  • sorl-thumbnail unit tests fail by 1 pixel (!)

  • Possible bug in ASP.net UpdatePanel control?

    - by Ben Robinson
    I have come across what seems to be an annoying bug with asp.net UpdatePanels in 2 seperate projects. If you have some kind of autopostback enabled control that can cause all of the controls in the update panel to have visible=false set, resulting in an empty update panel. When you change the autopostback control back to the postion that would re enable all of the controls in the update panel, it simply does not make a call back to the server and the update panel does not update. If you do anything else that makes a call back on the same page, then the update panel contents magically appear. It is as if asp.net has decided the update panel is empty so there is no point maikng a callback, even though making the call back would fill the updatepanel with content. The only way round this is to add a style of display:none to the controls instead of setting visible=false property. Then it works fine. Has anyone else encountered this problem? Is it a bug as i suspect or is it likely i am doing soemthing wrong? I haven't got time to post example code at the moment as the code i am using is too wrapped up in other unrealted things, if people think it would help i will create a simple example and post it when I get time.

  • How to avoid game rendering component circular references?

    - by CodexArcanum
    I'm working on a simple game design, and I wanted to break up my game objects into more reusable components. But I'm getting stuck on how exactly to implement the design I have in mind. Here's an example: I have a Logger object, whose job is simply to store a list of messages and render them to screen. You know, logging. Originally the Logger just held the list, and the game loop rendered it's contents. Then I moved the rendering logic into the Logger.Draw() method, and now I want to move it further into a LoggerRenderer object. In effect, I want to have the game loop call RenderAll, which will then call Logger.Render, which will in turn call the LoggerRenderer.Render and finally output the text. So the Logger needs to contain a Renderer object, but the Renderer needs access to the Logger's state (the message queue) in order to render. How do I resolve that? Should I be passing in the message queue and other state information explicitly to the Render method? Or should the game loop be calling the Renderer directly and it links back to the logger, but the RenderAll method never actually sees the logger object itself? This feels kind of like Command pattern, but I'm botching it up terribly.

    I am trying to unit test / verify that a method is being called on a dependency, by the system under test. The depenedency is IFoo. The dependent class is IBar. IBar is implemented as Bar. Bar will call Start() on IFoo in a new (System.Threading.Tasks.)Task, when Start() is called on Bar instance. Unit Test (Moq): [Test] public void StartBar_ShouldCallStartOnAllFoo_WhenFoosExist() { //ARRANGE //Create a foo, and setup expectation var mockFoo0 = new Mock<IFoo>(); mockFoo0.Setup(foo => foo.Start()); var mockFoo1 = new Mock<IFoo>(); mockFoo1.Setup(foo => foo.Start()); //Add mockobjects to a collection var foos = new List<IFoo> { mockFoo0.Object, mockFoo1.Object }; IBar sutBar = new Bar(foos); //ACT sutBar.Start(); //Should call mockFoo.Start() //ASSERT mockFoo0.VerifyAll(); mockFoo1.VerifyAll(); } Implementation of IBar as Bar: class Bar : IBar { private IEnumerable<IFoo> Foos { get; set; } public Bar(IEnumerable<IFoo> foos) { Foos = foos; } public void Start() { foreach(var foo in Foos) { Task.Factory.StartNew( () => { foo.Start(); }); } } } I appears that the issue is obviously due to the fact that the call to "foo.Start()" is taking place on another thread (/task), and the mock (Moq framework) can't detect it. But I could be wrong. Thanks

  • Apache tiles and body onload event. Known issue?

    - by Angus
    We're prototyping a new visual framework using Apache Tiles for markup templating. Often the document onload event (actually prototype's dom:loaded event) is getting fired before all DOM objects are actually loaded Is it possible that the tiles templates are loading in an asynchronous fashion and therefore doing an end run around the event handler? Has anyone else had this experience? Can anyone share a robust workaround? thanks in advance

  • GetEffectiveRightsFromAcl throws invalid acl error

    - by apoorv020
    I am trying to get the effective rights a user has on a file using interop in C#. Following is the code I am using : public static FileSystemRights GetFileEffectiveRights(string FileName, string UserName) { IntPtr pDacl, pZero = IntPtr.Zero; int Mask = 0; uint errorReturn = GetNamedSecurityInfo(FileName, SE_OBJECT_TYPE.SE_FILE_OBJECT, SECURITY_INFORMATION.Dacl , out pZero, out pZero, out pDacl, out pZero, out pZero); if (errorReturn != 0) { throw new Exception("Win error : " + errorReturn); } Program.TRUSTEE pTrustee = new TRUSTEE(); pTrustee.pMultipleTrustee = IntPtr.Zero; pTrustee.MultipleTrusteeOperation = (int)Program.MULTIPLE_TRUSTEE_OPERATION.NO_MULTIPLE_TRUSTEE; pTrustee.ptstrName = UserName; pTrustee.TrusteeForm = (int)Program.TRUSTEE_FORM.TRUSTEE_IS_NAME; pTrustee.TrusteeType = (int)Program.TRUSTEE_TYPE.TRUSTEE_IS_USER; errorReturn = GetEffectiveRightsFromAcl(pDacl, ref pTrustee, ref Mask); if (errorReturn != 0) { throw new Exception("Win error : " + errorReturn); } return (FileSystemRights)Mask; } This code works fine until I start modifying the ACL structure using the classes FileAccessRule and FileInfo, and then I start getting Windows Error 1336 : ERROR_INVALID_ACL. Same is the case if I debug the process call GetFileEffectiveRights once, pause the process,change the ACL through windows API, and resume and call GetFileEffectiveRights again(the 1st call succeeds but the second gives 1336.) What is going wrong?

  • Convert XML namespace prefixes with C#?

    - by jrista
    I have run into an exasperating problem getting a Java service client to communicate successfully with a WCF service. I have overcome many hurdles, and I believe that this is my last one. The problem boils down to how Java Axis + WSS4J seem to handle xml namespaces. The Java platform seem to be very rigid in what they expect for xml namespace prefixes, and as such, do not understand the WCF reply messages. My problem in a nutshell is as follows. I have an xml response similar to the following from my WCF service: <s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/" xmlns:a="http://www.w3.org/2005/08/addressing" xmlns:u="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd"> <s:Header> <a:Action s:mustUnderstand="1" u:Id="_3">http://tempuri.org/IProcessor/DoProcessingResponse</a:Action> <h:CorrelationID xmlns:h="http://tempuri.org/">1234</h:CorrelationID> <a:RelatesTo u:Id="_4">uuid:40f800a0-9613-4f4a-96c5-b9fd98085deb</a:RelatesTo> <o:Security s:mustUnderstand="1" xmlns:o="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd"> <!-- WS-Security header stuff --> </o:Security> </s:Header> <s:Body u:Id="_1"> <e:EncryptedData Id="_2" Type="http://www.w3.org/2001/04/xmlenc#Content" xmlns:e="http://www.w3.org/2001/04/xmlenc#"> <e:EncryptionMethod Algorithm="http://www.w3.org/2001/04/xmlenc#aes128-cbc"/> <e:CipherData> <e:CipherValue>NfA6XunmyLlT2ucA+5QneoawHm+imcaCltDAJC1mRZOSxoB6YGpDLY1FyVykPbPGDoFGUESLsmvvbD62sNnRrgE+AuKPo+1CD3DF4LfurRcEv9A50ba9V+ViqlrhydhK</e:CipherValue> </e:CipherData> </e:EncryptedData> </s:Body> </s:Envelope> This response uses simple one-character namespace prefixes for most things, such as 's' for SOAP Envelope, 'a' for WS-Addressing, 'o' for 'WS-Security', etc. The Java client, namely WSS4J, seems to expect the following: <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:wsa="http://www.w3.org/2005/08/addressing" xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd"> <soap:Header> <wsa:Action soap:mustUnderstand="1" wsu:Id="_3">http://tempuri.org/IProcessor/DoProcessingResponse</wsa:Action> <h:CorrelationID xmlns:h="http://tempuri.org/">1234</h:CorrelationID> <wsa:RelatesTo wsu:Id="_4">uuid:40f800a0-9613-4f4a-96c5-b9fd98085deb</a:RelatesTo> <wsse:Security soap:mustUnderstand="1" xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd"> <!-- WS-Security header stuff --> </wsse:Security> </soap:Header> <soap:Body u:Id="_1"> <xenc:EncryptedData Id="_2" Type="http://www.w3.org/2001/04/xmlenc#Content" xmlns:xenc="http://www.w3.org/2001/04/xmlenc#"> <xenc:EncryptionMethod Algorithm="http://www.w3.org/2001/04/xmlenc#aes128-cbc"/> <xenc:CipherData> <xenc:CipherValue>NfA6XunmyLlT2ucA+5QneoawHm+imcaCltDAJC1mRZOSxoB6YGpDLY1FyVykPbPGDoFGUESLsmvvbD62sNnRrgE+AuKPo+1CD3DF4LfurRcEv9A50ba9V+ViqlrhydhK</xenc:CipherValue> </xenc:CipherData> </xenc:EncryptedData> </soap:Body> </soap:Envelope> Upon receipt of my response message, the Java client and WSS4J seem to want to look up elements by their own internal xml aliases, such as 'wsa' for WS-Addressing, and 'wsse' for WS-Security Extensions. Since neither of those namespaces are present in the actual response xml, exceptions are thrown. I am wondering if there is any simple way to transform an xml document from one set of namespaces to another set using C#, .NET, and the System.Xml namespace. I've poked around with XmlNamespaceManager a bit, but it does not seem to fully support what I need...or at least, I have been unable to find any really useful examples, and am not fully sure how it works. I am trying to avoid having to write some heavy-duty process to handle this manually myself, as I do not want to drastically impact the performance of our services when called by a Java Axis/WSS4J client.

  • CI+JQuery+Ajax problem

    - by Sadat
    Calling the ajax called URL works well without ajax eg. http://localhost/ci/controller/method/param_value. But using ajax it doesnt work. Following are the code segment, i have just started with JQuery+Ajax with CI. Here is my controller: <?php class BaseController extends Controller{ public function BaseController(){ parent::Controller(); $this->load->helper('url'); } function index(){ $this->load->view('header'); $this->load->view('body'); $this->load->view('footer'); } function ajaxTest($testData=""){ $this->load->view('ajaxtest',array('test_data'=>$testData)); } } ? Here is View <?php echo $test_data; ? Ajax Call Function function testAjaxCall(){ $.get( base_url+'basecontroller/ajaxtest/test-value', function(responseData) { $("#test-div").html(responseData); } ); } Ajax Calling Page(button) <div id="test-div"></div><input type="button" onclick="testAjaxCall()" name="ajax-test" value="Test Ajax" /> JS base_url declaration <script type="text/javascript" src="<?php echo base_url();?>js/jquery.js"></script> <script type="text/javascript" src="<?php echo base_url();?>js/application-ajax-call.js"></script> <script type="text/javascript"> /* to make ajax call easy */ base_url = '<?php echo base_url();?>'; </script>
