Issue with setting the wsa headers

[Asanka Abeysinghe]

Hi All,
I'm trying to set the addressing headers of the response message but it 
dose not set with my input values. I'm setting the wsa:Action, 
wsa:RelatedTo by using the following code snippet.

               String replyAddress = 
mc.getOptions().getReplyTo().getAddress();
               AddressEndpoint endpoint = new AddressEndpoint();
               EndpointDefinition def = new EndpointDefinition();
               def.setAddress(replyAddress.trim());
               endpoint.setDefinition(def);
               org.apache.synapse.MessageContext rmc = new 
Axis2MessageContext(mc, synCfg, synEnv);
               rmc.setEnvelope(soapEnvelope);
               rmc.setTo(new EndpointReference(replyAddress));
               *rmc.setWSAAction(responseAction);*        //TODO wsa 
headers cannot see in the response message, it drops just before 
dispatching
               rmc.setSoapAction(responseAction);
               if (relatesTo!=null){
                   *rmc.setRelatesTo(new RelatesTo[]{relatesTo});*
               }
               rmc.setResponse(true);
               endpoint.send(rmc);

When I analyze the response message using TCPMON, both wsa:Action and 
the wsa:RelatedTo headers are missing and SOAPAction contains the 
SOAPAction of the original message (request). Any idea on what is 
happening ?
