UNIX Admin rail roaded to be java/jboss guy for development

Any Unix Admins out there who were tasked with upgrading and maintaining java/jboss installs and possibly related apps?

How did it work out?

Any tools to allow developers to tweak their java settings, like a console? I just started looking into this, if anyone has experience I'd appreciate it.

I'm looking for an efficient method to allow developers to make subtle changes without bottlenecking requests through me.

Actually, this should probably be moved to another forum. Apologies.
