How to create Session Beans??

mschmidke Oct 25, 2005 4:18 AM

Hello!

Excuse me, this seems to be a very very silly question, but I really didn't manage to find an answer for a couple of hours now ...

How can a session bean method create and return another session bean?

@Stateful class B {
...
}

@Stateless class A {
...
public B createB() {
...
}
}

I've simply tried "return new B();", but this cleary was no good idea. Instead of creating a remote reference, JBoss serializes the entire bean and sends it to the client. Not that good.

What's wrong? Surely there is only missing a secret Annotation. But I did not find any example!

Can anyone help?

Thank you very much!

Marcus.

try lookup(B.class); from jndi inside createB() and let jboss manage your beans.

Evrim,

thank you, this works ... but ... do I now have to remotely publish all methods which I only want to call locally?

@Resource SessionContext sc;
public B createB() {
B r=sc.lookup(B.class.getName());
r.initialize(...);
return r;
}

initialize() shall only be called locally, but B is the remote interface.

Hmm?

You cannot return your local lookup result(local proxy) to a remote vm. Its meaningless. Remote vm must lookup itself. Try using home.create(Object parameter); at the remote site. This is what j2ee suggests i think.
