Problem when using two clients..

[Mohamed Boutkhil]

Hello, I have written a little application ( compute surface and store in database) to test jonas performance. a session statefull bean handles two others beans:     - a stateless which computes surface     - and entitybean which saves the result. the client call statefull bean method in loop. it works fine. but when two clients carry out it in the same time, the server stops to execute client request from the second or third loop. If I remove entity bean from the execution process, it works fine. therefore my entity bean management seems not correct. the session bean which uses entity bean never removes it. it just call findByPrimaryKeys() and create() methods. I don't know how handle that. Thanks for help.. Mohamed Boukthil
