[jboss-user] [JBoss Seam] - seam webservice conversation id issues

I am trying to expose parts of my seam application as a web service. I am starting off with a simple login service. I am following the recommended pattern of using a  SLSB as a facade and exposing that as a webservice.

SLSB

  | 
  | @Stateless
  | @WebService(name = "DtlService", serviceName = "DtlService")
  | public class DtlService implements DtlServiceRemote
  | {
  | 	@WebMethod
  | 	public boolean login(String userName, String password)
  | 	{
  | 		Identity.instance().setUsername(userName);
  | 		Identity.instance().setPassword(password);
  | 		Identity.instance().login();
  | 		return Identity.instance().isLoggedIn();
  | 	}
  | }
  | 
  | 

The web service starts up fine and when I use the soapui toolkit to test this login service it works fine. I have no conversation Id in the soap header. The SOAP response from the seam web service has a conversation id in the response.

But when I use the apache axis & apache cxf toolkits to test the same web service, I get the following error.

Any advice regarding the conversation Id strategy for stateful web services      in seam would be helpful

Thanks in  advance
