Hi, I am getting NullPointerException during Performance Testing.
I am running a script which allows more than 50 users to run concurrently. It s a process where few users logs in, some other users log out. Its something like A, B, C log in and after sometime A logs out and D logs in. This way, it continues till all the action is completed. We are experiencing the following errors. 1. Null pointer exception - caused due to session being null. When individual users have different sessions, why does a session get null. Is it possible that one session is getting invalidated due to concurrency before the user logs out. 2. NotSerializableException:java.sql.ARRAY - 3. We have a Oracle connection pool which is set to 300 connections. This is different from Weblogic connections. After sometimes, the connection pool is reaching the limit. Maybe I could not explain the problems clearly. Can anyone give an explanation (and ofcourse solution) to above problems. Did anyone experience it earlier. Probably the whole thing can be attributed to UserSession (a Stateful Session Bean) becoming null.
