[jboss-dev-forums] [Design of POJO Server] - Re: Locking in DeploymentRepository

It sounds like you need a simple flag, or alternatively a latch instead of a lock:

If you really want a lock that can be shared across threads, in order to conform to the Lock interface, you need to use a thread local. Manik and I created one specific to jboss cache transactional locks here (you can derive from it if you like):
