[jboss-dev-forums] [EJB Development] - Entity bean deadlock

Hi! I have two entity beans for example: A, B There is a relation between these beans, and I have to be able to access B from A and A from B. A: getTitle() { return name + getB().getName(); } B: getTitle() { return name + getA().getName(); } When a thread calls A.getTitle() and an other thread calls B.getTitle(), there can be a deadlock: thread1 locks A; thread2 locks B; thread1 waits for B; thread2 waits for A -> deadlock What can I do to avoid these deadlock? Read-only method declaration isn't enough. I have to call the beans from each other. The real situation is much more difficult, it is only a simplified case. How can I obtain that a get method doesn't lock the bean itself? Thanks, Tamas View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4257064#...
