PK93689: WHILE USING HTTP GET, THE NULL VALUE FOR A DISPATCH INVOCATION USING THE XML/HTTP BINDING SHOULD BE ACCEPTABLE.

APAR status

• Closed as program error.

Error description

• ERROR DESCRIPTION:
  Using HTTP GET, a null value for a Dispatch invocation using
  the XML/HTTP binding results in an exception.

  *                      uses the Dispatch api with an XML/HTTP  *
  *                      GET designation.                        *

  * RECOMMENDATION:  Install a fixpack containing this APAR on   *
  *                  the WebSphere Application Server of the     *
  *                  client (sender) application.                *
  ****************************************************************
  The JAX-WS programming model allows a user to communicate with
  SOAP or XML/HTTP style messages.  If an XML/HTTP style is
  chosen, the user may choose to send messages via POST or GET
  HTTP protocols.
  
  A GET protocol implies that no payload is sent to the remote
  web service, but a payload is expected from the web service.
  
  Example:
  
          Service service = Service.create(GREETER_SERVICE);
          service.addPort(HTTP_GREETER_PORT,
                          HTTPBinding.HTTP_BINDING,
  "http://localhost:8080/jaxws-provider/provider/http/source/sayhi
  ?value=geronimo");
  
          Dispatch<Source> dispatch =
             service.createDispatch(HTTP_GREETER_PORT,
                                    Source.class,
                                    Service.Mode.MESSAGE);
          Map<String, Object> requestContext =
                        dispatch.getRequestContext();
          requestContext.put(MessageContext.HTTP_REQUEST_METHOD,
                             "GET");
          Source response = dispatch.invoke(null);
  
  Example error:
  
  java.lang.Throwable: The parameter cannot be a null
  value for a Dispatch invocation using the XML/HTTP binding.
  at
  org.apache.axis2.jaxws.client.dispatch.BaseDispatch.getProtocolE
  xception(BaseDispatch.java:437)
  
  The null argument should be tolerated since this is an
  acceptable usage pattern.
  

Problem conclusion

• A correction was made to the JAX-WS Dispatch runtime to
  tolerate invoke(null) for the XML/HTTP GET scenario.
  
  If a null input parameter is detected for other scenarios, the
  JAX-WS Dispatch runtime will correctly issue an error.
  
  The same problem is fixed in the V7.0 WebSphere Application
  Server by APAR PK92489.
  
  The fix for this APAR is currently targeted for inclusion in
  fix pack 6.1.0.29.  Please refer to the Recommended Updates
