Nope, still trying to figure out what's going on. I'm working on a couple of other things too. Should I be able to deploy clustered ejb's without the HAJNDI apparently working? Is the deal that I deploy on one server and can see them deployed on the other? Do they get bound into normal jndi so I can see them in jndiview? Does jndiview show whats in HAJNDI?
