Re: [Axis2] problem with WSDL2Java generated stubs and databinding

Nikola Zifra Tue, 27 Dec 2005 08:15:19 -0800

Hi iksrazal and Chintaka,
this is the part of the stub code generated by the 0.92 version of the WSDL2Java tool:

org.apache.axis2.clientapi.Call _call = new org.apache.axis2.clientapi.Call(_serviceContext);
            _call.setTransportInfo(this.senderTransport,this.listenerTransport,this.useSeparateListener);
            _call.setDoREST(this.doRest);

             org.apache.axis2.context.MessageContext _messageContext = getMessageContext();
            _call.setTo(this.toEPR);
            _call.setSoapAction("echoString");

And this is the part generated by 0.93 version of WSDL2Java tool:

             org.apache.axis2.client.Call _call = new org.apache.axis2.client.Call(_serviceContext);
             _call.setClientOptions(_clientOptions);
             org.apache.axis2.context.MessageContext _messageContext = getMessageContext();
              if(_clientOptions.getSoapAction() == null) {

              }

             if(_clientOptions.getAction() == null) {

           ; }

Notice that two different Call classes with different APIs are used in 0.92 and 0.93 version of the generated stub.You can't add line _call.setSoapAction("echoString") to the 0.93 version gen code because the org.apache.axis2.client.Call used in the 0.93 does not have method setSoapAction() . You can just use _clientOptions.setSoapAction("echoString") but it seems that it does not resolve my issue, because I am still getting
the exception I've complained about.

When I modify the 0.93 version code like this i am still getting the exception:

rg.apache.axis2.client.Call _call = new org.apache.axis2.client.Call(_serviceContext);
             _call.setClientOptions(_clientOptions);
             org.apache.axis2.context.MessageContext _messageContext = getMessageContext();
if(_clientOptions.getSoapAction() == null) {
                 System.out.println("\n\n\n>>> SETTING SOAP ACTION");
                 _clientOptions.setSoapAction("echoString");
}

org.apache.axis2.AxisFault: org.apache.axis2.AxisFault: Operation Not found EPR is http://localhost:8080/axis2/services/Axis2SampleDocLitPortType and WSA Action = "">     at org.apache.axis2.engine.DispatchingChecker.invoke(DispatchingChecker.java:70)
    at org.apache.axis2.engine.Phase.invoke(Phase.java:167)
    at org.apache.axis2.engine.AxisEngine.invokePhases(AxisEngine.java:443)
    at org.apache.axis2.engine.AxisEngine.receive(AxisEngine.java:137)

When I modify the 0.93 code in the following manner :

org.apache.axis2.client.Call _call = new org.apache.axis2.client.Call(_serviceContext);
             _call.setClientOptions(_clientOptions);

             org.apache.axis2.context.MessageContext _messageContext = getMessageContext();
             _clientOptions.setSoapAction("echoString");
             if(_clientOptions.getSoapAction() == null) {


              }

             if(_clientOptions.getAction() == null) {

            }
I got the the following exception:

org.apache.axis2.AxisFault: null; nested exception is:
    java.lang.NullPointerException
    at org.apache.axis2.AxisFault.makeFault(AxisFault.java:190)

    at org.apache.axis2.userguide.Axis2SampleDocLitPortTypeMessageReceiver.invokeBusinessLogic(Axis2SampleDocLitPortTypeMessageReceiver.java:106)
    ... 20 more

Could you pls. be more specific what part of the generated code should I modify and how?

Regards,
Nikola

Nikola, the iksrazal's method will fix the problem, BUT ..............
I should accept that its a bug in 0.93 re lease, which is now fixed in
current SVN head.
