Hi I use JBoss 3.0.4 in our Telecom application (JBoss rules). My next challenge is to make client calls to two different ORBs from a Session Bean. The two ORBs are Orbacus 3.3.1 and ACE/TAO 1.3. I hope the RMI-IIOP standard will do the job. But I know there is some obstacles. I kneed some good advice and references, sites etc. to prepare my self. Any advice is desired.
