Hello.
My name is Rafal Malinowski. I am working at Poznan Supercomputing and
Networing Center.
One of my task it to write a SSOS web-service client for SAML2 protocol.
It is described by simple wsdl file and some complex xsd files.
I've used axis2-1.4 to generate stub, it was not properly java file and
it has about 170 000 lines of code. I've decided that I don't need the
whole message structure (now it is only 300 lines of code) so I've
removed xsd files from wsdl and now I'm getting just a OMElement
structure. The problem is that I'am unable to serialize it ot string. It
just ommits about 90% of the message.
The wsdl file (xds files are cut off):
</message>
<message name="SSOSoapResponse">
<part name="parameters" element="samlp2:Response"/>
</message>
<portType name="SSOSPortType">
<operation name="SingleSignOn">
<input message="ssos:SSOSoapRequest"
wsaw:Action="urn:liberty:ssos:2006-08:AuthnRequest"/>
<output message="ssos:SSOSoapResponse"
wsaw:Action="urn:liberty:ssos:2006-08:Response"/>
</operation>
</portType>
<binding name="SSOSSoapBinding" type="ssos:SSOSPortType">
<S:binding style="document"
transport="http://schemas.xmlsoap.org/soap/http"/>
<operation name="SingleSignOn">
<input>
<S:body use="literal"/>
</input>
<output>
<S:body use="literal"/>
</output>
</operation>
</binding>
<service name="SSOService">
<port name="SSOSPortType" binding="ssos:SSOSSoapBinding">
<S:address location="http://example.com/idmapping"/>
</port>
</service>
</definitions>
The calling code:
OMElement response = ((SSOServiceStub) _stub)
.SingleSignOn(authnRequest);
The serialization code:
StringWriter stringWriter = new StringWriter();
response.serialize(stringWriter);
return stringWriter.toString();
The tcpdump SOAP response:

The serialization result looks like this:

ID="c61f62257d149cec89f8a873d6ffc94a"

IssueInstant="2008-06-25T20:08:30Z"><saml:Issuer>idp.man.poznan.pl</saml:Issuer>
</samlp:Response>
Can anyone tell me what happend with rest of my soap response?
The second problem is the oryginal java stub does not set SAOPAction
header, I had to add it manualy (the server requires it to be set to
proper value). How can I change the wsdl so the stub will set SOAPAction?
I hope someone know how to fix these problems or at least point me at
something that I didn't notice...
