I'm new to jboss. Can any pros out there give me some guidance on this?

The task I wanted to perform is to check the database for any uncompleted task, and perform redo.

In the current system, all processing request or queuing request are store in database. And problem occur when server crash, all processing request and queuing request that not yet been completed are ignore if no new request coming in after server crash.

Where to configure the jboss to run a particular class when it first started and restart after crash?

Thank you for reading.
