But I always get the following excpetion. :44:36,629 ERROR [SOAPFaultExceptionHelper] SOAP request exception vax.xml.rpc.JAXRPCException: Cannot create or send response message at org.jboss.ws.server.ServiceEndpoint.postProcessResponse(ServiceEndpoint.java:286) at org.jboss.ws.server.ServiceEndpoint.handleRequest(ServiceEndpoint.java:211) at org.jboss.ws.server.ServiceEndpointManager.processSOAPRequest(ServiceEndpointManager.java:355) at org.jboss.ws.server.StandardEndpointServlet.doPost(StandardEndpointServlet.java:115) at javax.servlet.http.HttpServlet.service(HttpServlet.java:717) at org.jboss.ws.server.StandardEndpointServlet.service(StandardEndpointServlet.java:76) at javax.servlet.http.HttpServlet.service(HttpServlet.java:810) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:252) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173) at org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:202) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:213) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:178) at org.jboss.web.tomcat.security.SecurityAssociationValve.invoke(SecurityAssociationValve.java:175) at org.jboss.web.tomcat.security.JaccContextValve.invoke(JaccContextValve.java:74) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:126) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:105) at org.jboss.web.tomcat.tc5.jca.CachedConnectionValve.invoke(CachedConnectionValve.java:156) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:107) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:148) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:869) at org.apache.coyote.http11.Http11BaseProtocol$Http11ConnectionHandler.processConnection(Http11BaseProtocol.java:664) at org.apache.tomcat.util.net.PoolTcpEndpoint.processSocket(PoolTcpEndpoint.java:527) at org.apache.tomcat.util.net.MasterSlaveWorkerThread.run(MasterSlaveWorkerThread.java:112) at java.lang.Thread.run(Thread.java:595) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4028261#...
