1:10 p.m.
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
