Manually Process a SOAP/JAX-WS Request

Question

Is there a way to process SOAP requests manually or on a per-request basis? Due to some very silly technical reasons in an existing system I cannot just publish JAX-WS services to an Endpoint created via the standard Endpoints factory. My situation is a bit messed up in that I am basically handed a raw InputStream from a ServerSocket and told to process it.

The data in the stream is being sent from a client that makes SOAP requests. The developer of the client provides a bunch of WSDL's and XSD's for generating the necessary server side classes using wsimport and xjc. All of it is JAX-WS and I would like to leverage as much of JAX-WS as possible to minimize the work I have to do.

Does anyone know where to start looking for how to do this? Is it even possible? My best guess at the moment is that I have to manually implement customer Endpoint or Provider.

Thanks!

You can process the raw input with the following steps. Just parse the incoming message as you would any XML stream

     try{ //throws a bunch of XML parsing related exceptions
      XMLInputFactory xFactory = XMLInputFactory.newFactory();
      XMLStreamReader xStream = xFactory.createXMLStreamReader(req.getInputStream());
      //Start skipping tags til you get to the message payload
      for(int nodeCount=0; nodeCount < 3; nodeCount++){
             xStream.nextTag(); //Jump <Envelope/>,<Body/>,<theMessageNode/>   
          }
      //You're now at the level of the actual class; Now unmarshal the payload  

      JAXBContext ctxt  = JAXBContext.newInstance(YourResponseClass.class);
      Unmarshaller um = ctxt.createUnmarshaller();
      JAXBElement<YourResponseClass.class> elem = um.unmarshal(xStream, YourResponseClass.class);             
      YourResponseClass theObj = elem.getValue();

     }
    catch(Exception ex) {

    }
