[jboss-user] [EJB 3.0] - difference between @Version and EntityManager.lock

Hi What is the difference between @Version and EntityManager.lock method? When I use @version then If one client is updating entity the version attribute is being increased and if another client wants to update the same entity the OptimisticLockException is thrown - there is no wainting for the second client? What is the situation with the lock method? Regards Adam View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4052817#...
