Issue sample MsgDispatcher. Call with null namespace URI for method null !

[herve attia]

Hello all,

I try to run sample based on a document-centric SOAP processing 
(MsgDispatcher) approach with Axis Alpha3.

The deployment of this service look like :

  <service name="POSubmission" pivot="MsgDispatcher">
    <option name="className" value="bwsj.services.POSubmission"/>
    <option name="methodName" value="doSubmission"/>
  </service>


To invoke this document service, I have a client which looks like :

...
String url = "http://localhost:8080/axis/services/POSubmission";
Service  service = new Service();
Call     client    = (Call) service.createCall();

client.setProperty( Call.NAMESPACE, "PoSubmission");

client.setTargetEndpointAddress( new java.net.URL(url) );

client.setRequestMessage(new Message(po, true));
client.setOperationName( "doSubmission" );

client.invoke();
...



I got the following error :
2002-03-09 14:39:58 StandardWrapperValve[jsp]: Servlet.service() for servlet 
jsp threw exception
Cannot invoke Call with null namespace URI for method null
        at org.apache.axis.client.Call.invoke(Call.java:1221)
        at bwsj.client.POSubmissionClient.invoke(Unknown Source)

so when I look at line 1221 of Call.java, it refers to this code section

        if ( body.getNamespaceURI() == null ) {
            throw new AxisFault("Call.invoke",
                   JavaUtils.getMessage("cantInvoke00", body.getName()),
                                        null, null);


Why my namespace and method name are null ?!

It sounds that doing the following is not enough !?

client.setProperty( Call.NAMESPACE, "PoSubmission");
...
client.setOperationName( "doSubmission" );



thanks
