[jbossws-users] [JBossWS] - Soap Error : NAMESPACE_ERR: An attempt is made to create or

Hello All, I am getting following error when my stateless ejb makes a soap call to other server to load some static data. The soap call works fine outside the Jboss container and only when I try to make this call from within Jboss I get this error. Also I wasnt expecting so see "org.jboss.ws.core.soap" in the stack trace, looks like somehow the SOAPContentElement class is being loaded from jbosall-cleintws.jar insted of the bundeled 'saaj' jars. Any insight is welcome. This is my first soap experience so please bear with me if there is something very simple which I have overlooked. Thanks in advance. -Amit /***ERROR*****/ org.w3c.dom.DOMException: NAMESPACE_ERR: An attempt is made to create or change an object in a way which is incorrect with regard to namespaces. at org.apache.xerces.dom.CoreDocumentImpl.checkDOMNSErr(Unknown Source) at org.apache.xerces.dom.AttrNSImpl.setName(Unknown Source) at org.apache.xerces.dom.AttrNSImpl.(Unknown Source) at org.apache.xerces.dom.CoreDocumentImpl.createAttributeNS(Unknown Source) at org.apache.xerces.dom.ElementImpl.setAttributeNS(Unknown Source) at org.jboss.ws.core.soap.SOAPElementImpl.setAttributeNS(SOAPElementImpl.java:747) at org.jboss.ws.core.soap.SOAPContentElement.setAttributeNS(SOAPContentElement.java:409) at org.jboss.ws.core.soap.SOAPElementImpl.addAttribute(SOAPElementImpl.java:174) at org.jboss.ws.core.soap.SOAPContentElement.addAttribute(SOAPContentElement.java:280) .... 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:585) at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:112) at org.jboss.ejb3.interceptor.InvocationContextImpl.proceed(InvocationContextImpl.java:166) at org.jboss.ejb3.interceptor.EJB3InterceptorsInterceptor.invoke(EJB3InterceptorsInterceptor.java:63) at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:101) at org.jboss.ejb3.entity.TransactionScopedEntityManagerInterceptor.invoke(TransactionScopedEntityManagerInterceptor.java:54) at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:101) at org.jboss.ejb3.AllowedOperationsInterceptor.invoke(AllowedOperationsInterceptor.java:47) at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:101) at org.jboss.aspects.tx.TxPolicy.invokeInOurTx(TxPolicy.java:79) at org.jboss.aspects.tx.TxInterceptor$Required.invoke(TxInterceptor.java:191) at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:101) at org.jboss.aspects.tx.TxPropagationInterceptor.invoke(TxPropagationInterceptor.java:76) at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:101) at org.jboss.ejb3.stateless.StatelessInstanceInterceptor.invoke(StatelessInstanceInterceptor.java:62) at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:101) at org.jboss.aspects.security.AuthenticationInterceptor.invoke(AuthenticationInterceptor.java:77) at org.jboss.ejb3.security.Ejb3AuthenticationInterceptor.invoke(Ejb3AuthenticationInterceptor.java:106) at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:101) at org.jboss.ejb3.ENCPropagationInterceptor.invoke(ENCPropagationInterceptor.java:46) at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:101) at org.jboss.ejb3.asynchronous.AsynchronousInterceptor.invoke(AsynchronousInterceptor.java:106) at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:101) at org.jboss.ejb3.stateless.StatelessContainer.dynamicInvoke(StatelessContainer.java:278) at org.jboss.aop.Dispatcher.invoke(Dispatcher.java:106) at org.jboss.aspects.remoting.AOPRemotingInvocationHandler.invoke(AOPRemotingInvocationHandler.java:82) at org.jboss.remoting.ServerInvoker.invoke(ServerInvoker.java:734) at org.jboss.remoting.transport.socket.ServerThread.processInvocation(ServerThread.java:560) at org.jboss.remoting.transport.socket.ServerThread.dorun(ServerThread.java:369) at org.jboss.remoting.transport.socket.ServerThread.run(ServerThread.java:165) /******/ View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4056227#...
