ECP Profile implementation...missing SOAP header

[Mitu Singh]

All,

I have a question about the ECP Profile implementation. I
can send a saml response to the ECP Client. This is how my response looks like:
<?xml version="1.0"
encoding="UTF-8"?>
<soap11:Envelope xmlns:soap11="http://schemas.xmlsoap.org/soap/envelope/">
  <soap11:Body>
     <saml2p:Response……
       
<saml2:Assertion……
       
</saml2:Assertion>
      </saml2p:Response>
    </soap11:Body>
</soap11:Envelope>
 
The response is missing the soap header element and the
ecp:Response element. The response should look like :
<SOAP-ENV:Envelope
xmlns:ecp="urn:oasis:names:tc:SAML:2.0:profiles:SSO:ecp"
xmlns:samlp="urn:oasis:names:tc:SAML:2.0:protocol"
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
<SOAP-ENV:Header>
               
<ecp:Response SOAP-ENV:mustUnderstand="1" 
               
               
      SOAP-ENV:actor="http://schemas.xmlsoap.org/soap/actor/next"
               
             
AssertionConsumerServiceURL="https://ServiceProvider.example.com/ecp_assertion_consumer"/>
</SOAP-ENV:Header>
<SOAP-ENV:Body>
<samlp:Response> ... </samlp:Response>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
 
I have tried a number of ways to include the header, but it
is not being set. This is how I have done it:                
                    HttpServletResponseAdapter
outTransport = new HttpServletResponseAdapter(httpResponse, false);        

BasicSAMLMessageContextmessageContext = new BasicSAMLMessageContext();               
             
messageContext.setOutboundMessageTransport(outTransport);               
             
SOAPObjectBuilder<Envelope> envelopeBuilder =
(SOAPObjectBuilder<Envelope>) builderFactory.getBuilder(Envelope.DEFAULT_ELEMENT_NAME);
       
Envelope envelope =
envelopeBuilder.buildObject();                 
        messageContext.setOutboundMessage(envelope);        
        messageContext.setOutboundSAMLMessage(authResponse);               
             
SAMLObjectBuilder<org.opensaml.saml2.ecp.Response> ecpResponseBuilder =
(SAMLObjectBuilder<org.opensaml.saml2.ecp.Response>)
builderFactory.getBuilder(org.opensaml.saml2.ecp.Response.DEFAULT_ELEMENT_NAME);
             
org.opensaml.saml2.ecp.Response ecpResponse = ecpResponseBuilder.buildObject();
             
ecpResponse.setSOAP11MustUnderstand(true);
             
ecpResponse.setSOAP11Actor(org.opensaml.saml2.ecp.Response.SOAP11_ACTOR_NEXT);
             
ecpResponse.setAssertionConsumerServiceURL("https://localhost:8443/sp_URL");                                
       
SOAPHelper.addHeaderBlock(messageContext, ecpResponse);
 
And
another way:
SOAPObjectBuilder<Envelope>
envelopeBuilder = (SOAPObjectBuilder<Envelope>)
builderFactory.getBuilder(Envelope.DEFAULT_ELEMENT_NAME);
       
Envelope envelope =
envelopeBuilder.buildObject();                                            
        SOAPObjectBuilder<Header>
headerBuilder = (SOAPObjectBuilder<Header>)
builderFactory.getBuilder(Header.DEFAULT_ELEMENT_NAME);
       
Header header = headerBuilder.buildObject();           
        SAMLObjectBuilder<org.opensaml.saml2.ecp.Response>
ecpResponseBuilder = (SAMLObjectBuilder<org.opensaml.saml2.ecp.Response>)
builderFactory.getBuilder(org.opensaml.saml2.ecp.Response.DEFAULT_ELEMENT_NAME);
             
org.opensaml.saml2.ecp.Response ecpResponse = ecpResponseBuilder.buildObject();
             
ecpResponse.setSOAP11MustUnderstand(true);
             
ecpResponse.setSOAP11Actor(org.opensaml.saml2.ecp.Response.SOAP11_ACTOR_NEXT);
             
ecpResponse.setAssertionConsumerServiceURL("https://localhost:8443/sp");               
       
header.getUnknownXMLObjects().add(ecpResponse);
       
envelope.setHeader(header);         
        messageContext.setOutboundMessage(envelope);
        messageContext.setOutboundSAMLMessage(authResponse);    
 
This is how the message is encoded:

SAMLMessageEncoder encoder = new HTTPSOAP11Encoder();encoder.encode(messageContext);

 
Does anyone have pointers for adding the soap headers?
Is the above code the correct way to setup and send the response?
