Can not invoke methods on remote interface via RMI/IIOP

[idow]

I'm trying to run a simple iiop stateless session bean from the org.jboss.test.helloiiop example.
I got the ._HelloHome_Stub using lookup and narrow, and managed to call it's create method and get a _Hello_Stub instance. I can see by looking at the JBoss logs that the stubs were downloaded to the client, and that they contain the right signatures for the bean home and remote interfaces.
I also saw that the IOR of the stubs the client has match the IOR that JBoss deployed.

But when the client invoke a method on the _Hello_Stub the following exception is thrown:

java.rmi.RemoteException: CORBA BAD_OPERATION 0 No; nested exception is:

I'm using JBoss 3.2.1 (I also tried it before on 3.0.1)

Any help would be appreciated...

Correction:
The returned IOR of the home interface matches the one printed to the JBoss log on deployment, but he IOR of the bean remote interface it got after invoking create on the home, DOES NOT match the remote IOR printed by JBOSS.

Anyone has and idea why is that so?

Thanks,
