It's a classic "I'll fix this later cock-up". Here's the code.     public boolean handleMessage(SOAPMessageContext context) throws ProtocolException     {         final boolean outbound = (Boolean)context.get(MessageContext.MESSAGE_OUTBOUND_PROPERTY);         if (outbound) {             return handleMessageOutbound(context);         } else {             return handlemessageInbound(context);         }     }       protected boolean handleMessageOutbound(SOAPMessageContext context) throws ProtocolException     {         try {             CoordinationContextType coordinationContext = CoordinationContextManager.getThreadContext();             if (coordinationContext != null) {                 final JAXBContext jaxbCtx = getJaxbContext();                   // insert a header into the current message containing the coordination context                 final SOAPMessage soapMessage = context.getMessage();                 final SOAPEnvelope soapEnvelope = soapMessage.getSOAPPart().getEnvelope();                 SOAPHeader soapHeader = soapEnvelope.getHeader() ;                 if (soapHeader == null)                 {                     soapHeader = soapEnvelope.addHeader() ;                 }                 . . .                 SOAPHeaderElement headerElement = soapHeader.addHeaderElement(getDummyQName());                 Marshaller marshaller = jaxbCtx.createMarshaller();                 marshaller.marshal(coordinationContext, headerElement);                 . . .             }           } catch (Exception se) {             throw new ProtocolException(se);         }           return true;     } and here's the code which returns the null pointer     private static JAXBContext jaxbContext;     private synchronized JAXBContext getJaxbContext()     {         if (jaxbContext == null) {             try {                 jaxbContext = JAXBContext.newInstance("org.oasis_open.docs.ws_tx.wscoor._2006._06");             } catch (JAXBException e) {                 // TODO log error here             }         }           return jaxbContext;     } I would have expected the ProtocolException to have resulted in an exception thrown from the client proxy method invocation but the proxy call just returned normally. Once again the classloader used to resollve the load under JAXBContext.newInstance was the war classloader. I worked round this by adding 'com.sun.xml.bind services export' to the dependencies in the war manifest.mf. However, I think it would be better if the modules which import it (both jaxws-client and jbossws-cxf-client) also exported it. It might be good if all the dependencies weer scrutinised to see whether they need re-exporting. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/608493#608493] Start a new discussion in JBoss Web Services Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
