Authentication exception, principal=null when running howto

[dchong]

I'm trying to run the SessionClient from the howto examples. I can login and find the home interface but when the create() method is called from the home interface an exception occurs. What am I doing wrong?
I am using JBoss 3.03.

here is the stack trace-

Ok, I figured it out. I have to add a module to my "TestClient" entry in auth.conf. The module I had to add was
"org.jboss.security.ClientLoginModule required
;"

Now my "TestClient" entry in auth.conf looks like this.
TestClient {
// A properties file LoginModule that supports CallerPrincipal mapping

org.jboss.security.auth.spi.UsersRolesLoginModule required
unauthenticatedIdentity=nobody
;
org.jboss.security.ClientLoginModule required
;
};


I can now run the SessionClient from my ide and get the following output.

+++ Running SessionClient with username=scott, password=echoman, example=example1
Created LoginContext
Found StatelessSessionHome
Created StatelessSession
Bean.echo('Hello') -> Hello
Found StatefulSessionHome
Created StatefulSession
Bean.noop() called
Bean.echo('Hello') -> Hello
Process terminated with exit code 0

I hope this helps someone else.

thanks
