Java2WSDL - Invalid WSDL for DOC/LIT wrapped operations that return Void 
-------------------------------------------------------------------------

                 Key: AXIS2-4378
                 URL: https://issues.apache.org/jira/browse/AXIS2-4378
             Project: Axis 2.0 (Axis2)
          Issue Type: Bug
          Components: wsdl
    Affects Versions: 1.4
            Reporter: Ben Reif


It seems that there is an inconsistency in the generated WSDL, with operations 
that return void, that comes from the Java2WSDLBuilder. My MEP is 
http://www.w3.org/ns/wsdl/robust-in-only. After it runs, it generates a 
<wsdl:output> element in the <wsdl:portType> operation, but there isn't one in 
the <wsdl:binding> operation definition. This causes some WSDL validators to 
fail.

To generate the <wsdl:output> in the <wsdl:portType> it seems that the 
AxisService2WSDL11.generatePortType() method, it's checking for that MEP and 
then just checking to make sure that the AxisMessage from the AxisOperation is 
not null.

To generate the <wsdl:output> in the <wsdl:binding> it seems that the 
AxisService2WSDL11.generateSoap11Binding() method is checking for that MEP and 
then just checking that the AxisBindingMessage on the AxisBindingOperation is 
not null. In this case I think that the AxisBindingMessage is null, because the 
WSDLUtil.isOutputPresentForMEP() method is not checking for the Robust-In-Only 
MEP, however the output AxisMessage on the AxisOperation is not null.

I think that either the WSDLUtil.isOutputPresentForMEP() method should be fixed 
to check for that MEP, or else the AxisService2WSDL11.generateSoap11Binding() 
method should also check the output message on the AxisOperation.
