[Axis2] After changes to WSDL to make it WS-I compliant, Stub
throws Nullpointer
My Axis2 1.3 based webservice has been working well so far, but it was not totally WS-I compliant - the Eclipse based WS-I compliance validation check failed with the message "WS-I: (BP2120) A binding has operations that are not unique." There were 2 operations with no input parameters which caused this failure. I rectified that by adding an empty request element and the WS-I validation check passed. But thereafter, when I regenerated the stubs and tested a client call to the stub (that used to worked earlier), now it failed with the following exception:
Exception in thread "main" java.lang.NullPointerException
at com.selectica.ws.ecm.wsdlgen.ECMServiceSoapStub.IsPDFWordConversionEnabled(ECMServiceSoapStub.java:549)
at CallSCMWebServiceStub.main(CallSCMWebServiceStub.java:23)
The nullpointer is in the Stub line#468 (the toEnvelope call) because the dummyWrappedType passed to it is null.
Is this a bug in the Axis2 Stub generation?
Another way of calling the webservice without using the Axis2 generated stub works fine even after the WS-I compliance changes.
I am attaching
- the wsdl (trimmed for simplicity) and the stub class before and after the WS-I compliance changes
- my client code (CallSCMWebServiceStub.java) that calls the service using the stub (this gives the above exception after the service was made WS-I compliant)
- my client code (CallSCMWebServiceSvcUrl.java) that calls the service without using the stub (this works even after the WS-I compliance changes)

Thanks Amila. I verified and found that this problem is nonexistent in Axis2 1.4.1.
