User sessions crossed

[mathpets]

Hi all,

I am experiencing a very strange issue. I have an application that stores a user's information (serializable bean) in the HttpSession after the user has succesfully logs in. Sometimes, user A will get user B's bean rather than his own. Can anyone tell me why this is happening?

I am not using clustering. I'm using JBoss 3.2.2RC4 and JDK 1.4.

Any hints would be deeply appreciated! Thank you so much in advance.

Sorry, one more thing. The reason why I didn't use clustering is because this application only serves 10 users. I didn't think it was necessary.
