Hello!!! I'm a problem with WS! I'm using Jboss 4.0.5 and jdk1.6. I've created a Junit file that call to my simply web service, but when invoke to the webMethod ... the following exception it's thrown: | java.lang.NoClassDefFoundError: com/sun/xml/messaging/saaj/soap/AttachmentPartImpl | at com.sun.xml.ws.message.AttachmentUnmarshallerImpl.<clinit>(AttachmentUnmarshallerImpl.java:55) | at com.sun.xml.ws.client.sei.ResponseBuilder$DocLit.readResponse(ResponseBuilder.java:500) | at com.sun.xml.ws.client.sei.SyncMethodHandler.invoke(SyncMethodHandler.java:242) | at com.sun.xml.ws.client.sei.SyncMethodHandler.invoke(SyncMethodHandler.java:210) | at com.sun.xml.ws.client.sei.SEIStub.invoke(SEIStub.java:103) | at $Proxy25.hola(Unknown Source) | at Prueba2.testMain(Prueba2.java:22) | at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) | at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) | at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) | at java.lang.reflect.Method.invoke(Method.java:597) | at junit.framework.TestCase.runTest(TestCase.java:164) | at junit.framework.TestCase.runBare(TestCase.java:130) | at junit.framework.TestResult$1.protect(TestResult.java:106) | at junit.framework.TestResult.runProtected(TestResult.java:124) | at junit.framework.TestResult.run(TestResult.java:109) | at junit.framework.TestCase.run(TestCase.java:120) | at junit.framework.TestSuite.runTest(TestSuite.java:230) | at junit.framework.TestSuite.run(TestSuite.java:225) | at org.eclipse.jdt.internal.junit.runner.junit3.JUnit3TestReference.run(JUnit3TestReference.java:130) | at org.eclipse.jdt.internal.junit.runner.TestExecution.run(TestExecution.java:38) | at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:460) | at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:673) | at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:386) | at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:196) | Caused by: java.lang.ClassNotFoundException: com.sun.xml.messaging.saaj.soap.AttachmentPartImpl | at java.net.URLClassLoader$1.run(URLClassLoader.java:200) | at java.security.AccessController.doPrivileged(Native Method) | at java.net.URLClassLoader.findClass(URLClassLoader.java:188) | at java.lang.ClassLoader.loadClass(ClassLoader.java:307) | at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301) | at java.lang.ClassLoader.loadClass(ClassLoader.java:252) | at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:320) | ... 25 more | But I don't know why, because this class is in rt.jar of jdk 6. In the remote server ( where it's allocated the ws ) it been executed fine. The problem is when the response come back. Any ideas to fix this??? Thanks in advance PD: I've following the instructions of http://jbossws.jboss.org/mediawiki/index.php?title=Install_JBossWS to build my WS.
