Alright. I'd indeed avoid these problems running BPEL and the ESB on two different server instances, by the way, but I thought I'd go for the merge attempt for simplicity (but you're right in that it might make it more work, I've come to see that now.) I might've misunderstood the point you were trying to make in that last sentence though. do you mean it's more of a requirement that jBoss ESB supports BPEL because it is an ESB?
