Hi all, We are using entity beans version 2.x, jboss 4.0.5. When we load test our system, we keep getting messages such as: javax.ejb.EJBException: Reentrant method call detected: .... As far as I can see our code does not contain the situation when Bean A calls bean B which, in turn, calls back to bean A I suspect that the problem might have something to do with concurrency(trying to access the same entity bean(same id) from different threads) I tried to set the Reentrant flag to True for the problematic bean, but this resulted in other exceptions. I will appreciate any help on this subject Thanks, Nadav View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4106789#...
