Subject [jira] Commented: (AXIS2-2902) jaxbri databinding cannot handle multiple XML elements of the same type

Denis Rachal commented on AXIS2-2902:
-------------------------------------

The example WSDL given is not actually realistic. "ReplyTo" and "From" are actually WS Addressing
headers and should not be in the body. I put them in the body to illustrate the problem. Had
I put them in the headers where they belong it would have exposed another bug: http://issues.apache.org/jira/browse/AXIS2-2852.

As WS Addressing headers they should be allowed as headers in any of the messages in the WSDL
that support WS Addressing. While "From" is only optional, "ReplyTo" is required by WS Addressing
if a reply is expected. This is the case for many, if not most, SOAP requests. Not using "From"
at all avoids the problem. This may turn up in other cases of headers, though.

I have two elements of the same type. If I define two messages in my WSDL with the two different
XML elements that are of the same type, a message is generated for the second element with
the name of the first element.
> WSDL is attached for an example. 
> In short. I have defined two request messages:
> 	<wsdl:message name="ReplyToRequestMessage">
> 		<wsdl:part name="ReplyTo" element="wsa:ReplyTo" />
> 	</wsdl:message>
> and 
> 	<wsdl:message name="FromResponseMessage">
> 		<wsdl:part name="From" element="wsa:From" />
> 	</wsdl:message>
> WS Addressing (http://schemas.xmlsoap.org/ws/2004/08/addressing/) defines the elements
"ReplyTo" & "From" as follows:
>   <xs:element name="From" type="wsa:EndpointReferenceType" /> 
>   <xs:element name="ReplyTo" type="wsa:EndpointReferenceType" /> 
> They are both the same type, "wsa:EndpointReferenceType"
> The stub code generated has a toOM() method that is used to generate both the "ReplyTo"
element and the "From" element, but the method has hardcoded the element name "ReplyTo" making
it incorrect for the use with the "From" case. See generated code below:
>                 private org.apache.axiom.om.OMElement toOM(org.xmlsoap.schemas.ws._2004._08.addressing.EndpointReferenceType
param, org.apache.axiom.soap.SOAPFactory factory, boolean optimizeContent) {
>                     try {
>                         javax.xml.bind.JAXBContext context = org_xmlsoap_schemas_ws__2004__08_addressing_EndpointReferenceType;
>                         javax.xml.bind.Marshaller marshaller = context.createMarshaller();
>                         marshaller.setProperty(javax.xml.bind.Marshaller.JAXB_FRAGMENT,
Boolean.TRUE);            
>                         JaxbRIDataSource source = new JaxbRIDataSource( org.xmlsoap.schemas.ws._2004._08.addressing.EndpointReferenceType.class,
