Hi All,
   I am using attached WSDL to generate java source with org.apache.axis2.wsdl.codegen.CodeGenerationEngine class using ADB binding. It is successfully able to generate the java source but on calling web service i get an exception reporting  invalid sub-element "STD_Types_INT2_outReturn". I have checked the SOAP request and response message both looks in shape.




WSDL is rpc/enc and has multipart message in couple of operation response. Here are few lines from wsdl...

<wsdl:message name="STD_Types_INT2_outRequest">
<wsdl:part name="int2" type="xsd:int"/>
</wsdl:message>

<wsdl:message name="STD_Types_INT2_outResponse">
<wsdl:part name="STD_Types_INT2_outReturn" type="xsd:int"/>
<wsdl:part name="int2" type="xsd:int"/>
</wsdl:message>

<wsdl:operation name="STD_Types_INT2_out" parameterOrder="int2">
<wsdl:input message="impl:STD_Types_INT2_outRequest" name="STD_Types_INT2_outRequest"/>
<wsdl:output message="impl:STD_Types_INT2_outResponse" name="STD_Types_INT2_outResponse"/>
</wsdl:operation>

Exception is thrown from the code generated by Axis2, that do parsing of SOAP response to Java Object this is done by a method of generated Stub class(attached herewith)..

 java.lang.Object fromOM(org.apache.axiom.om.OMElement param,java.lang.Class type, java.util.Map extraNamespaces) throws org.apache.axis2.AxisFault

Looking at the parser code, i can make out that parser excepts "int2" to be the first element/parameter in Soap body but SOAP message has "STD_Types_INT2_outReturn" as first parameter as evident from wsdl leading to failure of parser. WSDL specification does not define parameterOrder for out message  giving space to confusion of parsing  SOAP response to Java  object.
Will i be right to say that this is a bug in Axis2 ? If "no" what is the way out and if "yes" when can i expect it to be fixed, i have a major release on calender, quick response is highly appriciated.

Thanks,
Rahul Yadav
