How to define some mehod for global resource initializtion and recycle in JBoss container!

[kong song]

I have some customize data and process need to be initialized only once when Jboss AS is starting.
I have used some ejb Life Cycle Event to handle it,but the result seems not well.

so,How can I define some method or service for initializing global resource and container just only call once? and How about recycle such resource only when the container is closing.

Thanks!
