Hello! I'm using Jboss 4.0.4GA to deploy a SessionBean-based webservice. When I use 1.5 JDK to run JBoss there's no problem and the webservice and it's clients run smoothly, the problem arises when Jboss is started with Sun's 1.6 (6.0) JDK, then this exception is thrown every time a client tries to consume the service: 14:24:07,046 ERROR [SOAPFaultExceptionHelper] SOAP request exception java.lang.UnsupportedOperationException: setProperty must be overridden by all subclasses of SOAPMessage at javax.xml.soap.SOAPMessage.setProperty(SOAPMessage.java:424) at org.jboss.ws.soap.SOAPMessageImpl.(SOAPMessageImpl.java:65) at org.jboss.ws.soap.MessageFactoryImpl.createMessageInternal(MessageFactoryImpl.java:209) at org.jboss.ws.soap.MessageFactoryImpl.createMessage(MessageFactoryImpl.java:142) at org.jboss.ws.server.ServiceEndpoint.handleRequest(ServiceEndpoint.java:190) 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:619) Seems to me that Jboss has some kind of incompatibility with sun's 1.6 implementation. Is this any known error? thanks! View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4000956#...
