• Exception Handling Differences Between 32/64 Bit

  - by Alois Kraus

  I do quite a bit of debugging .NET applications but from time to time I see things that are impossible (at a first look). I may ask you dear reader what your mental exception handling model is. Exception handling is easy after all right? Lets suppose the following code:         private void F1(object sender, EventArgs e)         {             try             {                 F2();             }             catch (Exception ex)             {                 throw new Exception("even worse Exception");             }           }           private void F2()         {             try             {                 F3();             }             finally             {                 throw new Exception("other exception");             }         }           private void F3()         {             throw new NotImplementedException();         }   What will the call stack look like when you break into the catch(Exception) clause in Windbg (32 and 64 bit on .NET 3.5 SP1)? The mental model I have is that when an exception is thrown the stack frames are unwound until the catch handler can execute. An exception does propagate the call chain upwards.   So when F3 does throw an exception the control flow will resume at the finally handler in F2 which does throw another exception hiding the original one (that is nasty) and then the new Exception will be catched in F1 where the catch handler is executed. So we should see in the catch handler in F1 as call stack only the F1 stack frame right? Well lets try it out in Windbg. For this I created a simple Windows Forms application with one button which does execute the F1 method in its click handler. When you compile the application for 64 bit and the catch handler is reached you will find with the following commands in Windbg   Load sos extension from the same path where mscorwks was loaded in the current process .loadby sos mscorwks   Beak on clr exceptions sxe clr   Continue execution g   Dump mixed call stack container C++  and .NET Stacks interleaved 0:000> !DumpStack OS Thread Id: 0x1d8 (0) Child-SP         RetAddr          Call Site 00000000002c88c0 000007fefa68f0bd KERNELBASE!RaiseException+0x39 00000000002c8990 000007fefac42ed0 mscorwks!RaiseTheExceptionInternalOnly+0x295 00000000002c8a60 000007ff005dd7f4 mscorwks!JIT_Throw+0x130 00000000002c8c10 000007fefa6942e1 WindowsFormsApplication1!WindowsFormsApplication1.Form1.F1(System.Object, System.EventArgs)+0xb4 00000000002c8c60 000007fefa661012 mscorwks!ExceptionTracker::CallHandler+0x145 00000000002c8d60 000007fefa711a72 mscorwks!ExceptionTracker::CallCatchHandler+0x9e 00000000002c8df0 0000000077b055cd mscorwks!ProcessCLRException+0x25e 00000000002c8e90 0000000077ae55f8 ntdll!RtlpExecuteHandlerForUnwind+0xd 00000000002c8ec0 000007fefa637c1a ntdll!RtlUnwindEx+0x539 00000000002c9560 000007fefa711a21 mscorwks!ClrUnwindEx+0x36 00000000002c9a70 0000000077b0554d mscorwks!ProcessCLRException+0x20d 00000000002c9b10 0000000077ae5d1c ntdll!RtlpExecuteHandlerForException+0xd 00000000002c9b40 0000000077b1fe48 ntdll!RtlDispatchException+0x3cb 00000000002ca220 000007fefdaeaa7d ntdll!KiUserExceptionDispatcher+0x2e 00000000002ca7e0 000007fefa68f0bd KERNELBASE!RaiseException+0x39 00000000002ca8b0 000007fefac42ed0 mscorwks!RaiseTheExceptionInternalOnly+0x295 00000000002ca980 000007ff005dd8df mscorwks!JIT_Throw+0x130 00000000002cab30 000007fefa6942e1 WindowsFormsApplication1!WindowsFormsApplication1.Form1.F2()+0x9f 00000000002cab80 000007fefa71b5b3 mscorwks!ExceptionTracker::CallHandler+0x145 00000000002cac80 000007fefa70dcd0 mscorwks!ExceptionTracker::ProcessManagedCallFrame+0x683 00000000002caed0 000007fefa7119af mscorwks!ExceptionTracker::ProcessOSExceptionNotification+0x430 00000000002cbd90 0000000077b055cd mscorwks!ProcessCLRException+0x19b 00000000002cbe30 0000000077ae55f8 ntdll!RtlpExecuteHandlerForUnwind+0xd 00000000002cbe60 000007fefa637c1a ntdll!RtlUnwindEx+0x539 00000000002cc500 000007fefa711a21 mscorwks!ClrUnwindEx+0x36 00000000002cca10 0000000077b0554d mscorwks!ProcessCLRException+0x20d 00000000002ccab0 0000000077ae5d1c ntdll!RtlpExecuteHandlerForException+0xd 00000000002ccae0 0000000077b1fe48 ntdll!RtlDispatchException+0x3cb 00000000002cd1c0 000007fefdaeaa7d ntdll!KiUserExceptionDispatcher+0x2e 00000000002cd780 000007fefa68f0bd KERNELBASE!RaiseException+0x39 00000000002cd850 000007fefac42ed0 mscorwks!RaiseTheExceptionInternalOnly+0x295 00000000002cd920 000007ff005dd968 mscorwks!JIT_Throw+0x130 00000000002cdad0 000007ff005dd875 WindowsFormsApplication1!WindowsFormsApplication1.Form1.F3()+0x48 00000000002cdb10 000007ff005dd786 WindowsFormsApplication1!WindowsFormsApplication1.Form1.F2()+0x35 00000000002cdb60 000007ff005dbe6a WindowsFormsApplication1!WindowsFormsApplication1.Form1.F1(System.Object, System.EventArgs)+0x46 00000000002cdbc0 000007ff005dd452 System_Windows_Forms!System.Windows.Forms.Control.OnClick(System.EventArgs)+0x5a   Hm okaaay.

The call stack has been unwound and we do see only some frames into the history where the debugger was smart enough to find out that we have called F2 from F1. The exception handling on 64 bit systems does work quite differently which seems to have the nice property to remember the called methods not only during the first pass of exception filter clauses (during first pass all catch handler are called if they are going to catch the exception which is about to be thrown)  but also when the actual stack unwind has taken place. This makes it possible to follow not only the call stack right at the moment but also to look into the “history” of the catch/finally clauses. In a 64 bit process you only need to look at the ExceptionTracker to find out if a catch or finally handler was called. The two frames ProcessManagedCallFrame/CallHandler does indicate a finally clause whereas CallCatchHandler/CallHandler indicates a catch clause. That was a interesting one. Oh and by the way if you manage to load the Microsoft symbols you can also find out the hidden exception which. When you encounter in the call stack a line 0016eb34 75b79617 KERNELBASE!RaiseException+0x58 ====> Exception Code e0434f4d cxr@16e850 exr@16e838 Then it is a good idea to execute .exr 16e838 !analyze –v to find out more. In the managed world it is even easier since we can dump the objects allocated on the stack which have not yet been garbage collected to look at former method parameters.

• 401 Using Multiple Authentication methods IE 10 only

  - by jon3laze

  I am not sure if this is more of a coding issue or server setup issue so I've posted it on stackoverflow and here... On our production site we've run into an issue that is specific to Internet Explorer 10. I am using jQuery doing an ajax POST to a web service on the same domain and in IE10 I am getting a 401 response, IE9 works perfectly fine. I should mention that we have mirrored code in another area of our site and it works perfectly fine in IE10. The only difference between the two areas is that one is under a subdomain and the other is at the root level. www.my1stdomain.com vs. portal.my2nddomain.com The directory structure on the server for these are: \my1stdomain\webservice\name\service.aspx \portal\webservice\name\service.aspx Inside of the \portal\ and \my1stdomain\ folders I have a page that does an ajax call, both pages are identical. $.ajax({ type: 'POST', url: '/webservice/name/service.aspx/function', cache: false, contentType: 'application/json; charset=utf-8', dataType: 'json', data: '{ "json": "data" }', success: function() { }, error: function() { } }); I've verified permissions are the same on both folders on the server side. I've applied a workaround fix of placing the <meta http-equiv="X-UA-Compatible" value="IE=9"> to force compatibility view (putting IE into compatibility mode fixes the issue). This seems to be working in IE10 on Windows 7, however IE 10 on Windows 8 still sees the same issue. These pages are classic asp with the headers that are being included, also there are no other meta tags being used. The doctype is being specified as <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//" "http://www.w3.org/TR/html4/loose.dtd"> on the portal page and <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> on the main domain. UPDATE1 I used Microsoft Network Monitor 3.4 on the server to capture the request. I used the following filter to capture the 401: Property.HttpStatusCode.StringToNumber == 401 This was the response - Http: Response, HTTP/1.1, Status: Unauthorized, URL: /webservice/name/service.aspx/function Using Multiple Authetication Methods, see frame details ProtocolVersion: HTTP/1.1 StatusCode: 401, Unauthorized Reason: Unauthorized - ContentType: application/json; charset=utf-8 - MediaType: application/json; charset=utf-8 MainType: application/json charset: utf-8 Server: Microsoft-IIS/7.0 jsonerror: true - WWWAuthenticate: Negotiate - Authenticate: Negotiate WhiteSpace: AuthenticateData: Negotiate - WWWAuthenticate: NTLM - Authenticate: NTLM WhiteSpace: AuthenticateData: NTLM XPoweredBy: ASP.NET Date: Mon, 04 Mar 2013 21:13:39 GMT ContentLength: 105 HeaderEnd: CRLF - payload: HttpContentType = application/json; charset=utf-8 HTTPPayloadLine: {"Message":"Authentication failed.","StackTrace":null,"ExceptionType":"System.InvalidOperationException"} The thing here that really stands out is Unauthorized, URL: /webservice/name/service.aspx/function Using Multiple Authentication Methods With this I'm still confused as to why this only happens in IE10 if it's a permission/authentication issue. What was added to 10, or where should I be looking for the root cause of this?

• The Return Of __FILE__ And __LINE__ In .NET 4.5

  - by Alois Kraus

  Good things are hard to kill. One of the most useful predefined compiler macros in C/C++ were __FILE__ and __LINE__ which do expand to the compilation units file name and line number where this value is encountered by the compiler. After 4.5 versions of .NET we are on par with C/C++ again. It is of course not a simple compiler expandable macro it is an attribute but it does serve exactly the same purpose. Now we do get CallerLineNumberAttribute  == __LINE__ CallerFilePathAttribute        == __FILE__ CallerMemberNameAttribute  == __FUNCTION__ (MSVC Extension)   The most important one is CallerMemberNameAttribute which is very useful to implement the INotifyPropertyChanged interface without the need to hard code the name of the property anymore. Now you can simply decorate your change method with the new CallerMemberName attribute and you get the property name as string directly inserted by the C# compiler at compile time.   public string UserName { get { return _userName; } set { _userName=value; RaisePropertyChanged(); // no more RaisePropertyChanged(“UserName”)! } } protected void RaisePropertyChanged([CallerMemberName] string member = "") { var copy = PropertyChanged; if(copy != null) { copy(new PropertyChangedEventArgs(this, member)); } } Nice and handy. This was obviously the prime reason to implement this feature in the C# 5.0 compiler. You can repurpose this feature for tracing to get your hands on the method name of your caller along other stuff very fast now. All infos are added during compile time which is much faster than other approaches like walking the stack. The example on MSDN shows the usage of this attribute with an example public static void TraceMessage(string message, [CallerMemberName] string memberName = "", [CallerFilePath] string sourceFilePath = "", [CallerLineNumber] int sourceLineNumber = 0) { Console.WriteLine("Hi {0} {1} {2}({3})", message, memberName, sourceFilePath, sourceLineNumber); }   When I do think of tracing I do usually want to have a API which allows me to Trace method enter and leave Trace messages with a severity like Info, Warning, Error When I do print a trace message it is very useful to print out method and type name as well. So your API must either be able to pass the method and type name as strings or extract it automatically via walking back one Stackframe and fetch the infos from there. The first glaring deficiency is that there is no CallerTypeAttribute yet because the C# compiler team was not satisfied with its performance.   A usable Trace Api might therefore look like   enum TraceTypes { None = 0, EnterLeave = 1 << 0, Info = 1 << 1, Warn = 1 << 2, Error = 1 << 3 } class Tracer : IDisposable { string Type; string Method; public Tracer(string type, string method) { Type = type; Method = method; if (IsEnabled(TraceTypes.EnterLeave,Type, Method)) { } } private bool IsEnabled(TraceTypes traceTypes, string Type, string Method) { // Do checking here if tracing is enabled return false; } public void Info(string fmt, params object[] args) { } public void Warn(string fmt, params object[] args) { } public void Error(string fmt, params object[] args) { } public static void Info(string type, string method, string fmt, params object[] args) { } public static void Warn(string type, string method, string fmt, params object[] args) { } public static void Error(string type, string method, string fmt, params object[] args) { } public void Dispose() { // trace method leave } } This minimal trace API is very fast but hard to maintain since you need to pass in the type and method name as hard coded strings which can change from time to time. But now we have at least CallerMemberName to rid of the explicit method parameter right? Not really. Since any acceptable usable trace Api should have a method signature like Tracexxx(… string fmt, params [] object args) we not able to add additional optional parameters after the args array. If we would put it before the format string we would need to make it optional as well which would mean the compiler would need to figure out what our trace message and arguments are (not likely) or we would need to specify everything explicitly just like before . There are ways around this by providing a myriad of overloads which in the end are routed to the very same method but that is ugly. I am not sure if nobody inside MS agrees that the above API is reasonable to have or (more likely) that the whole talk about you can use this feature for diagnostic purposes was not a core feature at all but a simple byproduct of making the life of INotifyPropertyChanged implementers easier. A way around this would be to allow for variable argument arrays after the params keyword another set of optional arguments which are always filled by the compiler but I do not know if this is an easy one. The thing I am missing much more is the not provided CallerType attribute. But not in the way you would think of. In the API above I did add some filtering based on method and type to stay as fast as possible for types where tracing is not enabled at all. It should be no more expensive than an additional method call and a bool variable check if tracing for this type is enabled at all. The data is tightly bound to the calling type and method and should therefore become part of the static type instance. Since extending the CLR type system for tracing is not something I do expect to happen I have come up with an alternative approach which allows me basically to attach run time data to any existing type object in super fast way. The key to success is the usage of generics.   class Tracer<T> : IDisposable { string Method; public Tracer(string method) { if (TraceData<T>.Instance.Enabled.HasFlag(TraceTypes.EnterLeave)) { } } public void Dispose() { if (TraceData<T>.Instance.Enabled.HasFlag(TraceTypes.EnterLeave)) { } } public static void Info(string fmt, params object[] args) { } /// <summary> /// Every type gets its own instance with a fresh set of variables to describe the /// current filter status. /// </summary> /// <typeparam name="T"></typeparam> internal class TraceData<UsingType> { internal static TraceData<UsingType> Instance = new TraceData<UsingType>(); public bool IsInitialized = false; // flag if we need to reinit the trace data in case of reconfigured trace settings at runtime public TraceTypes Enabled = TraceTypes.None; // Enabled trace levels for this type } } We do not need to pass the type as string or Type object to the trace Api. Instead we define a generic Api that accepts the using type as generic parameter. Then we can create a TraceData static instance which is due to the nature of generics a fresh instance for every new type parameter. My tests on my home machine have shown that this approach is as fast as a simple bool flag check. If you have an application with many types using tracing you do not want to bring the app down by simply enabling tracing for one special rarely used type. The trace filter performance for the types which are not enabled must be therefore the fasted code path. This approach has the nice side effect that if you store the TraceData instances in one global list you can reconfigure tracing at runtime safely by simply setting the IsInitialized flag to false. A similar effect can be achieved with a global static Dictionary<Type,TraceData> object but big hash tables have random memory access semantics which is bad for cache locality and you always need to pay for the lookup which involves hash code generation, equality check and an indexed array access. The generic version is wicked fast and allows you to add more features to your tracing Api with minimal perf overhead. But it is cumbersome to write the generic type argument always explicitly and worse if you do refactor code and move parts of it to other classes it might be that you cannot configure tracing correctly. I would like therefore to decorate my type with an attribute [CallerType] class Tracer<T> : IDisposable to tell the compiler to fill in the generic type argument automatically. class Program { static void Main(string[] args) { using (var t = new Tracer()) // equivalent to new Tracer<Program>() { That would be really useful and super fast since you do not need to pass any type object around but you do have full type infos at hand. This change would be breaking if another non generic type exists in the same namespace where now the generic counterpart would be preferred. But this is an acceptable risk in my opinion since you can today already get conflicts if two generic types of the same name are defined in different namespaces. This would be only a variation of this issue. When you do think about this further you can add more features like to trace the exception in your Dispose method if the method is left with an exception with that little trick I did write some time ago. You can think of tracing as a super fast and configurable switch to write data to an output destination or to execute alternative actions. With such an infrastructure you can e.g. Reconfigure tracing at run time. Take a memory dump when a specific method is left with a specific exception. Throw an exception when a specific trace statement is hit (useful for testing error conditions). Execute a passed delegate which e.g. dumps additional state when enabled. Write data to an in memory ring buffer and dump it when specific events do occur (e.g. method is left with an exception, triggered from outside). Write data to an output device. …. This stuff is really useful to have when your code is in production on a mission critical server and you need to find the root cause of sporadic crashes of your application. It could be a buggy graphics card driver which throws access violations into your application (ok with .NET 4 not anymore except if you enable a compatibility flag) where you would like to have a minidump or you have reached after two weeks of operation a state where you need a full memory dump at a specific point in time in the middle of an transaction. At my older machine I do get with this super fast approach 50 million traces/s when tracing is disabled. When I do know that tracing is enabled for this type I can walk the stack by using StackFrameHelper.GetStackFramesInternal to check further if a specific action or output device is configured for this method which is about 2-3 times faster than the regular StackTrace class. Even with one String.Format I am down to 3 million traces/s so performance is not so important anymore since I do want to do something now. The CallerMemberName feature of the C# 5 compiler is nice but I would have preferred to get direct access to the MethodHandle and not to the stringified version of it. But I really would like to see a CallerType attribute implemented to fill in the generic type argument of the call site to augment the static CLR type data with run time data.

• NullReferenceException when changing skin/theme via Application.Current.Resources

  - by CoolCat

  I am writing an wpf application with multiple skins. The code to switch theme is as below: try { Application.Current.Resources.MergedDictionaries.Add( resource ); } catch( Exception ex ) { } The first time the code is called (to switch to a new theme), it is executed successfully; however, any subsequent calls to the same code would throw System.NullReferenceException. The way I set up my themes are similar to what described here: http://www.codewrecks.com/blog/index.php/2008/05/22/simple-skinnable-and-theme-management-in-wpf-user-interface/. Has anyone seen this error before? How do I go about debugging this since the exception is thrown else where? Any help is greatly appreciated.

• System.Reflection and InvokeMember, storing type, assembly, and object in a class

  - by Cyclone

  I have tested code to call a method inside of a compiled DLL, and it works. I created a class to store the object, type, and loaded assembly, but something is lost in translation because it is unable to find the member I wish to invoke. If I create a type, object, and assembly, and properly load everything into these and perform InvokeMember on the type, it works just fine. However, when I use the things inside of my class, it throws a MissingMemberException and does not invoke the member, obviously. What am I doing wrong? The member in question is a subroutine which takes one argument, a string. This is quite frustrating. Code being called: Dim MyLoadedAssembly As New LoadedAssembly() MyLoadedAssembly.MyAssembly = Assembly.LoadFrom("display.dll") MyLoadedAssembly.MyObject = MyLoadedAssembly.MyAssembly.CreateInstance("Display.UI.Window") MyLoadedAssembly.MyType = MyLoadedAssembly.MyAssembly.GetType("Display.UI.Window") Dim args() As Object = {"test"} MyLoadedAssembly.InvokeMember("Show", args) Private Class LoadedAssembly Public MyType As Type Public MyObject As Object Public MyAssembly As Assembly Public Function InvokeMember(ByVal name As String, ByVal args() As Object) Return MyType.InvokeMember(name, BindingFlags.Default Or BindingFlags.InvokeMethod Or BindingFlags.GetProperty Or BindingFlags.Instance, Nothing, MyObject, args) End Function End Class Code inside of display.dll: Namespace UI Public Class Window Private wind As New System.Windows.Forms.Form Public FullScreen As Boolean = False Public Overloads Sub Show(ByVal text As String) wind.Show() wind.Text = text End Sub Public Overloads Sub Show() wind.Show() End Sub End Class End Namespace The root namespace for display.dll is Display. Why is my code only working when not within this class? System.MissingMethodException was unhandled Message="Method 'Display.UI.Window.Show' not found."

My wsdd looks like this. <globalConfiguration> <parameter name="adminPassword" value="admin"/> <parameter name="sendXsiTypes" value="true"/> <parameter name="sendMultiRefs" value="true"/> <parameter name="sendXMLDeclaration" value="true"/> <parameter name="axis.sendMinimizedElements" value="true"/> <requestFlow> <handler type="java:org.apache.axis.handlers.JWSHandler"> <parameter name="scope" value="session"/> </handler> <handler type="java:org.apache.axis.handlers.JWSHandler"> <parameter name="scope" value="request"/> <parameter name="extension" value=".jwr"/> </handler> </requestFlow> </globalConfiguration> <handler name="LocalResponder" type="java:org.apache.axis.transport.local.LocalResponder"/> <handler name="URLMapper" type="java:org.apache.axis.handlers.http.URLMapper"/> <handler name="Authenticate" type="java:org.apache.axis.handlers.SimpleAuthenticationHandler"/> <transport name="http"> <requestFlow> <handler type="URLMapper"/> <handler type="java:org.apache.axis.handlers.http.HTTPAuthHandler"/> </requestFlow> </transport> <transport name="local"> <responseFlow> <handler type="LocalResponder"/> </responseFlow> </transport> <service name="helloService" provider="java:RPC" style="document" use="literal"> <parameter name="className" value="ws.example.HelloService"/> <parameter name="allowedMethods" value="*"/> <parameter name="scope" value="application"/> </service> I am able to deploy it successfully. If I try to invoke the method which returns a String, it is successfully returning the String. But when I invoke the method which returns an object, I am getting the following error. AxisFault faultCode: {http://schemas.xmlsoap.org/soap/envelope/}Server.userException faultSubcode: faultString: org.xml.sax.SAXParseException: Premature end of file. faultActor: faultNode: faultDetail: {http://xml.apache.org/axis/}stackTrace:org.xml.sax.SAXParseException: Premature end of file. at org.apache.xerces.util.ErrorHandlerWrapper.createSAXParseException(Unknown Source) at org.apache.xerces.util.ErrorHandlerWrapper.fatalError(Unknown Source) at org.apache.xerces.impl.XMLErrorReporter.reportError(Unknown Source) at org.apache.xerces.impl.XMLErrorReporter.reportError(Unknown Source) at org.apache.xerces.impl.XMLVersionDetector.determineDocVersion(Unknown Source) at org.apache.xerces.parsers.XML11Configuration.parse(Unknown Source) at org.apache.xerces.parsers.XML11Configuration.parse(Unknown Source) at org.apache.xerces.parsers.XMLParser.parse(Unknown Source) at org.apache.xerces.parsers.AbstractSAXParser.parse(Unknown Source) at org.apache.xerces.jaxp.SAXParserImpl$JAXPSAXParser.parse(Unknown Source) at javax.xml.parsers.SAXParser.parse(SAXParser.java:395) 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:424) 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:2765) at org.apache.axis.client.Call.invoke(Call.java:2748) at org.apache.axis.client.Call.invoke(Call.java:2424) at org.apache.axis.client.Call.invoke(Call.java:2347) at org.apache.axis.client.Call.invoke(Call.java:1804) at ws.example.ws.HelloServiceSoapBindingStub.getAwardById(HelloServiceSoapBindingStub.java:202) at Test.main(Test.java:21) Can any body help?

• Create Hello World with RESTful web service and Jersey

  - by Harry Pham

  I follow tutorial here on how to create web service using RESTful web service and Jersey and I get kind of stuck. The code is from HelloWorld3 in the tutorial I linked above. Here is the code. I use Netbean6.8 + glassfish v3 RESTGreeting.java create using JAXB. This class represents the HTML message in Java package com.sun.rest; import javax.xml.bind.annotation.XmlRootElement; import javax.xml.bind.annotation.XmlElement; @XmlRootElement(name = "restgreeting") public class RESTGreeting { private String message; private String name; /** * Creates new instance of Greeting */ public RESTGreeting() { } /* Create new instance of Greeting * with parameters message and name */ public RESTGreeting( String message, String name) { this.message = message; this.name = name; } /** Getter for message * return value for message * */ @XmlElement public String getMessage() { return message; } public void setMessage(String message) { this.message = message; } /* Getter for name * return name */ @XmlElement public String getName() { return name; } public void setName(String name) { this.name = name; } } HelloGreetingService.java creates a RESTful web service that returns an HTML message package com.sun.rest; import javax.ws.rs.core.Context; import javax.ws.rs.core.UriInfo; import javax.ws.rs.Consumes; import javax.ws.rs.PUT; import javax.ws.rs.Path; import javax.ws.rs.GET; import javax.ws.rs.Produces; import javax.ws.rs.QueryParam; @Path("helloGreeting") public class HelloGreetingService { @Context private UriInfo context; /** Creates a new instance of HelloGreetingService */ public HelloGreetingService() { } /** * Retrieves representation of an instance of com.sun.rest.HelloGreetingService * @return an instance of java.lang.String */ @GET @Produces("text/html") public RESTGreeting getHtml(@QueryParam("name") String name) { return new RESTGreeting( getGreeting(), name); } private String getGreeting() { return "Hello "; } /** * PUT method for updating or creating an instance of HelloGreetingService * @param content representation for the resource * @return an HTTP response with content of the updated or created resource. */ @PUT @Consumes("text/html") public void putHtml(String content) { } } However when i deploy it on Glassfish, and run it. It generate an exception. I try to debug using netbean 6.8, and figure out that this line return new RESTGreeting(getGreeting(), name); in HelloGreetingService.java cause the exception. But not sure why. Here is the stacktrace javax.ws.rs.WebApplicationException at com.sun.jersey.spi.container.ContainerResponse.write(ContainerResponse.java:268) at com.sun.jersey.server.impl.application.WebApplicationImpl._handleRequest(WebApplicationImpl.java:1029) at com.sun.jersey.server.impl.application.WebApplicationImpl.handleRequest(WebApplicationImpl.java:941) at com.sun.jersey.server.impl.application.WebApplicationImpl.handleRequest(WebApplicationImpl.java:932) at com.sun.jersey.spi.container.servlet.WebComponent.service(WebComponent.java:384) at com.sun.jersey.spi.container.servlet.ServletContainer.service(ServletContainer.java:451) at com.sun.jersey.spi.container.servlet.ServletContainer.service(ServletContainer.java:632) at javax.servlet.http.HttpServlet.service(HttpServlet.java:847) at org.apache.catalina.core.StandardWrapper.service(StandardWrapper.java:1523) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:279) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:188) at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:641) at com.sun.enterprise.web.WebPipeline.invoke(WebPipeline.java:97) at com.sun.enterprise.web.PESessionLockingStandardPipeline.invoke(PESessionLockingStandardPipeline.java:85) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:185) at org.apache.catalina.connector.CoyoteAdapter.doService(CoyoteAdapter.java:332) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:233) at com.sun.enterprise.v3.services.impl.ContainerMapper.service(ContainerMapper.java:165) at com.sun.grizzly.http.ProcessorTask.invokeAdapter(ProcessorTask.java:791) at com.sun.grizzly.http.ProcessorTask.doProcess(ProcessorTask.java:693) at com.sun.grizzly.http.ProcessorTask.process(ProcessorTask.java:954) at com.sun.grizzly.http.DefaultProtocolFilter.execute(DefaultProtocolFilter.java:170) at com.sun.grizzly.DefaultProtocolChain.executeProtocolFilter(DefaultProtocolChain.java:135) at com.sun.grizzly.DefaultProtocolChain.execute(DefaultProtocolChain.java:102) at com.sun.grizzly.DefaultProtocolChain.execute(DefaultProtocolChain.java:88) at com.sun.grizzly.http.HttpProtocolChain.execute(HttpProtocolChain.java:76) at com.sun.grizzly.ProtocolChainContextTask.doCall(ProtocolChainContextTask.java:53) at com.sun.grizzly.SelectionKeyContextTask.call(SelectionKeyContextTask.java:57) at com.sun.grizzly.ContextTask.run(ContextTask.java:69) at com.sun.grizzly.util.AbstractThreadPool$Worker.doWork(AbstractThreadPool.java:330) at com.sun.grizzly.util.AbstractThreadPool$Worker.run(AbstractThreadPool.java:309) at java.lang.Thread.run(Thread.java:637)

• Replace JBoss error page with Axis2 fault XML response

  - by Dario

  I'm developing a webservice with Axis2 1.4.1 on JBoss 4.2.3/Tomcat 5.5.27 and Java 1.5.0 (15-b04). It works flawlessly but when an exception happens I get a JBoss error 500 HTML page instead of an Axis2 XML/SOAP fault. This behavoir is vexing, because it difficults to handle errors in the webservice client or in SoapUI while developing. Can I change this to get the SOAP fault? Maybe it's just an Axis2 or JBoss parameter, but I didn't find any clue about. EDIT: Here goes the new stacktrace: [ERROR] WSDoAllReceiver: security processing failed org.apache.axis2.AxisFault: WSDoAllReceiver: security processing failed at org.apache.rampart.handler.WSDoAllReceiver.processBasic(WSDoAllReceiver.java:214) at org.apache.rampart.handler.WSDoAllReceiver.processMessage(WSDoAllReceiver.java:86) at org.apache.rampart.handler.WSDoAllHandler.invoke(WSDoAllHandler.java:72) at org.apache.axis2.engine.Phase.invoke(Phase.java:317) at org.apache.axis2.engine.AxisEngine.invoke(AxisEngine.java:264) at org.apache.axis2.engine.AxisEngine.receive(AxisEngine.java:163) at org.apache.axis2.transport.http.HTTPTransportUtils.processHTTPPostRequest(HTTPTransportUtils.java:275) at org.apache.axis2.transport.http.AxisServlet.doPost(AxisServlet.java:133) at javax.servlet.http.HttpServlet.service(HttpServlet.java:647) at javax.servlet.http.HttpServlet.service(HttpServlet.java:729) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:269) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:188) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:213) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:172) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:117) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:108) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:174) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:875) at org.apache.coyote.http11.Http11BaseProtocol$Http11ConnectionHandler.processConnection(Http11BaseProtocol.java:665) at org.apache.tomcat.util.net.PoolTcpEndpoint.processSocket(PoolTcpEndpoint.java:528) at org.apache.tomcat.util.net.LeaderFollowerWorkerThread.runIt(LeaderFollowerWorkerThread.java:81) at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool.java:689) at java.lang.Thread.run(Thread.java:595) Caused by: org.apache.ws.security.WSSecurityException: The security token could not be authenticated or authorized at org.apache.ws.security.processor.UsernameTokenProcessor.handleUsernameToken(UsernameTokenProcessor.java:155) at org.apache.ws.security.processor.UsernameTokenProcessor.handleToken(UsernameTokenProcessor.java:53) at org.apache.ws.security.WSSecurityEngine.processSecurityHeader(WSSecurityEngine.java:311) at org.apache.ws.security.WSSecurityEngine.processSecurityHeader(WSSecurityEngine.java:228) at org.apache.rampart.handler.WSDoAllReceiver.processBasic(WSDoAllReceiver.java:211) ... 23 more [ERROR] Servlet.service() para servlet AxisServlet lanzó excepción java.lang.NullPointerException at org.apache.rampart.RampartMessageData.<init>(RampartMessageData.java:308) at org.apache.rampart.MessageBuilder.build(MessageBuilder.java:61) at org.apache.rampart.handler.RampartSender.invoke(RampartSender.java:64) at org.apache.axis2.engine.Phase.invoke(Phase.java:317) at org.apache.axis2.engine.AxisEngine.invoke(AxisEngine.java:264) at org.apache.axis2.engine.AxisEngine.sendFault(AxisEngine.java:520) at org.apache.axis2.transport.http.AxisServlet.handleFault(AxisServlet.java:416) at org.apache.axis2.transport.http.AxisServlet.processAxisFault(AxisServlet.java:379) at org.apache.axis2.transport.http.AxisServlet.doPost(AxisServlet.java:167) at javax.servlet.http.HttpServlet.service(HttpServlet.java:647) at javax.servlet.http.HttpServlet.service(HttpServlet.java:729) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:269) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:188) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:213) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:172) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:117) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:108) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:174) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:875) at org.apache.coyote.http11.Http11BaseProtocol$Http11ConnectionHandler.processConnection(Http11BaseProtocol.java:665) at org.apache.tomcat.util.net.PoolTcpEndpoint.processSocket(PoolTcpEndpoint.java:528) at org.apache.tomcat.util.net.LeaderFollowerWorkerThread.runIt(LeaderFollowerWorkerThread.java:81) at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool.java:689) at java.lang.Thread.run(Thread.java:595) EDIT 2: After giving the bounty I found that I was wrong about 1.2.9-SNAPSHOT version of Axiom. I built it again, made sure the jars where correctly copied to lib directory and it worked! Finally, it was an Axiom bug, as said in the links provided by Vineet. Thanks!

• What would cause ANY .NET application to crash immediately... except a project I create and Debug in

  - by blak3r

  My software recently got deployed to a customer who said that the application was crashing immediately after it started. After some initial debugging, the customer provided me remote access to one of the computers which was unable to run the application. I found that the crash wasn't specific to my application. Any application which depended on the .NET framework crashed immediately. Conveniently, Visual Studio 2008 was installed so I created a quick hello world application on it and clicked Debug. The application worked fine. But, then when I tried to execute the generated binaries in the /bin/Debug/HelloWorld.exe directory outside of visual studio it crashed. List of things i've tried (UPDATED): I checked that "Everyone" has Read&Execute permissions for c:\Windows. To test that the problem was with the .NET Framework (and not my application), I attempted to download Paint .NET on to the computers. The setup frontend crashed in the same manner. Performed a repair of the .NET framework as outlined in http://support.microsoft.com/kb/908077 (Boy was this fun and time consuming). No luck. Installed .NET 3.5 SP1 (before it just had .NET 3.5) Note: my application targets 2.0 so I did this more as a long shot... but i learned in the process that .NET 3.5 SP1 also updates the underlying frameworks. Ran Aaron Stebner's .NET Setup Verification Tool. This tool indicated that .NET was successfully installed. (I forget if i checked all the versions but at least 2.0 worked). Tested some mini hello world applications which were targeted for .NET 2.0 and .NET 3.5 and both crashed in the same way. Tried launching .NET apps via windbg cmd line. Doing this did allow me invoke my simple hello world applications. So, simple .NET hello world works when invoked by windbg or by launching via debug in visual studio... but doesn't if i try to execute it standalone. I created a dump file using WinDbg. It wasn't all that revealing to me.

• How to return a complex object in axis web service .

  Hi all, I am writing a simple web service to return an object with 2 properties. I am embedding the service into an existing web application. My wsdd looks like this. <globalConfiguration> <parameter name="adminPassword" value="admin"/> <parameter name="sendXsiTypes" value="true"/> <parameter name="sendMultiRefs" value="true"/> <parameter name="sendXMLDeclaration" value="true"/> <parameter name="axis.sendMinimizedElements" value="true"/> <requestFlow> <handler type="java:org.apache.axis.handlers.JWSHandler"> <parameter name="scope" value="session"/> </handler> <handler type="java:org.apache.axis.handlers.JWSHandler"> <parameter name="scope" value="request"/> <parameter name="extension" value=".jwr"/> </handler> </requestFlow> </globalConfiguration> <handler name="LocalResponder" type="java:org.apache.axis.transport.local.LocalResponder"/> <handler name="URLMapper" type="java:org.apache.axis.handlers.http.URLMapper"/> <handler name="Authenticate" type="java:org.apache.axis.handlers.SimpleAuthenticationHandler"/> <transport name="http"> <requestFlow> <handler type="URLMapper"/> <handler type="java:org.apache.axis.handlers.http.HTTPAuthHandler"/> </requestFlow> </transport> <transport name="local"> <responseFlow> <handler type="LocalResponder"/> </responseFlow> </transport> <service name="helloService" provider="java:RPC" style="document" use="literal"> <parameter name="className" value="ws.example.HelloService"/> <parameter name="allowedMethods" value="*"/> <parameter name="scope" value="application"/> </service> I am able to deploy it successfully.

• xamlparser error after clickonce deployment.Application crashing after installation

  - by black sensei

  Hello Good People, I've built an WPF application with visual studio 2008 and created an installer for it.Works fine so far.I realized it lacks the automatic updates feature, and after trying several solutions, i decided to give a try to clickonce deployment.After a successful deployment on a network server, i 've noticed that the application crashes after installation of the downloaded app.It complains about this: Cannot create instance of 'Login' defined in assembly 'MyApplication, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'.

in the msi from setup project works fine.so i cannot see where the error is comming from since i can have design view. Question 1 : Does any one have a similar issue, or is that a known issue? Question 2 : If it's a known issue then what are alternative.I might give up on the clickonce but then i my automatic update feature will be lost (as in there is none which is not ovekill or seriously outdated that i can find right now). thanks for reading this and for pointing me to the right direction.

• Problems with shutting down JBoss in Eclipse if I change JNDI port

  - by Balint Pato

  1st phase I have a problem shutting down my running JBoss instance under Eclipse since I changed the JNDI port of JBoss.

• Defines JEE 5 the handling of commit error using bean managed transactions?

  - by marabol

  I'm using glassfish 2.1 and 2.1.1. If I've a bean method annotated by @TransactionAttribute(value = TransactionAttributeType.REQUIRES_NEW). After doing some JPA stuff the commit fails in the afterCompletion-Phase of JTS. GlassFish logs this failure only. And the caller of this bean method has no chance to know something goes wrong. So I wonder, if there is any definition how a jee 5 server has to handle exceptions while commiting. I would expect any runtime exception. I'm using stateless beans. With SessionSynchronisation I could get the commit failue, if I use statefull beans. Is it possible to intercept, so I can throw an exception, that I've declared in my interface? This is the whole exception stacktrace:

• Illegal cross thread operation exception, unable to handle it

  - by yeah1000

  Hello, i am using visual C# express 2008. I SOMETIMES get the illegal cross thread operation in my invoke method when i try to run my project. It use the same invoke method in many places but its only at the beginning of another thread that i get the error. I check the InvokeRequired property, invoke the same method and in the 'else' condition and create a temporary variable and assign it the text of my control. But on that line, in the 'else' statement, inside the Invoking method i sometimes get the exception. What could be the cause? How to get rid of it? It does not occur often, but it is still a bug... Code: // Delegate: private delegate void ChangeTextDelegate(string text); // Method: public static void ChangeText(string text) { if (richtextbox1.InvokeRequired) { richtextbox1.Invoke(new ChangeTextDelegate(ChangeText), new object[] { text }); } else { int startIndex; startIndex = richtextbox1.TextLength; // <- Exception points here. // ... } } Stack trace: System.InvalidOperationException was unhandled Message="Cross-thread operation not valid: Control 'SomeClass' accessed from a thread other than the thread it was created on."

  Hi I am using Twitter4J API on GAE/J. I want to use the request token when user came to my page. (called back URL). And press refresh button. I write following code for that. But When user press refresh button. I got Authentication credentials error. Please see the stacktrance. It works fine when user first time used that token. HomeServlet.java code: HttpSession session = request.getSession(); twitter.setOAuthConsumer(FFConstants.CONSUMER_KEY, FFConstants.CONSUMER_SECRET); String token = (String) session.getAttribute("token"); String authorizedToken = (String)session.getAttribute("authorizedToken"); User user = null; if (!token.equals(authorizedToken)){ AccessToken accessToken = twitter.getOAuthAccessToken( token, (String) session .getAttribute("tokenSecret")); twitter.setOAuthAccessToken(accessToken); user = twitter.verifyCredentials(); session.setAttribute("authorizedToken", token); session.setAttribute("user", user); }else{ user = (User)session.getAttribute("user"); } TwitterUser twitterUser = new TwitterUser(); twitterUser.setFollowersCount(user.getFollowersCount()); twitterUser.setFriendsCount(user.getFriendsCount()); twitterUser.setFullName(user.getName()); twitterUser.setScreenName(user.getScreenName()); twitterUser.setLocation(user.getLocation()); Please suggest how I can do that. I have seen on many website. They retain the user with the same token. Even if user press browser refresh buttion again and again. Please help.
