I need clients to login into my network (using Java, XML RPC). The server has to authenticate the clients and they get a single key, which authorizes them to access various other clients in the network. I've never used JBoss, or any other application server before, but JBoss seems to be exactly what I need? If that's the case, how difficult is JBoss to set up (security, etc.)? How many requests can JBoss handle? As said it's new territory for me.
