JBoss interoperability - call a JBoss EJB

[weberjn <we...@gmail.com>]

Hi,

we'd like to have an EJB deployed in Geronimo call an EJB deployed in JBoss.

One could assume that should be possible, because both use RMI/IIOP as
network protocol, shouldn't it?
But one would need the JBoss NamingContextFactory and all needed classes in
the classpath?
So I guess one would use a pure Java Corba client to the JBoss EJB and run
it in the Geronimo bean.

If that does not work, I'll try to deploy a Corba servant (that calls the
JBoss EJB) in JBoss and call the servant from Geronimo (as discussed on the
JBoss list: http://community.jboss.org/thread/88976)

Thanks,
Juergen

Neither geronimo/openejb nor (AFAIK) jboss use RMI/IIOP as the default remote ejb protocol.  You need to enable CORBA to get this protocol.

yes, that should work fine, and IMO is your best bet for getting this to work.

Theoretically CORBA interoperability should let you use the geronimo corba client to communicate with the jboss orb.  You'll need to set up the CSS security on geronimo and TSS security on jboss.  However IMO CORBA interop is mostly a myth.  We test interop between geronimo/yoko and glassfish but judging by the problems we run into you'd be very lucky to get interop between yoko and the jboss ORB without fixing bugs in both orbs.  On the other hand I don't think anyone's tried it so there's always a chance it will work fine.
