I'm having trouble generating a Service instance using ServiceFactory. I keep getting NPEs. The server side is no problem. The ties get generated OK and deploy with no problem on Tomcat. But, I can't seem to generate the Service on the client side from the WSDL without getting NPEs.

Any suggestions will be much appreciated.

Here is the code for instantiation.

      String wsdlURL = "http://localhost:8080/jaxrpc-OrderProcessor/orderproc?WSDL";
      String namespaceURI = "http://www.xyzcorp.com/css/wsdl";
      String serviceName = "orderProcessingService";
      URL urlWSDL = new URL(wsdlURL);
      QName qnameService =
        new QName(namespaceURI, serviceName);
      log.info("urlWSDL = " + urlWSDL + NL +
               "qnameService = " + qnameService);
      Service orderService =
        serviceFac.createService(urlWSDL, qnameService);

Here is part of the WSDL:

  xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/"
  xmlns:soapbind="http://schemas.xmlsoap.org/wsdl/soap/"
