Description

Wsdl abstract:

.....
<wsdl:message name="initiateRequestInputMessage">
<wsdl:part name="payload" element="tns:...."/>
</wsdl:message>
<wsdl:message name="emptyMessage"/>
<wsdl:portType name="myPortType">
<wsdl:operation name="initiateRequest">
<wsdl:input message="tns:initiateRequestInputMessage"/>
<wsdl:output message="tns:emptyMessage"/>
</wsdl:operation>
</wsdl:portType>
.....

Given this kind of wsdl, WSDL2Java throws the following exception:

Exception in thread "main" org.apache.axis2.wsdl.codegen.CodeGenerationException: java.lang.RuntimeException: No element reference in message emptyMessage

Empty messages like the one above are valid according to WS-I Basic Profile 1.1:
-------------------------------------------------
4.4.1 Bindings and Parts
.....
Use of wsdl:message elements with zero parts is permitted in Document styles to permit operations that can send or receive envelopes with empty soap:Bodys.

Such messages are also supproted by ADB.
