How can I set up a general EJB 3 Bean as a service ???
A service in general has multiple users that sometimes need to wait for one another but most of the time need to be able to run in paralell.
A service that has global data used by all users of the service... on the same machine .....
Take a look at Service POJOs under JBoss Extensions to EJB3
