Shared PersistenceContext possible ?

[balamg]

Currently, I am using SFSBs that use an extended PC. However, multiple users logging in will result in multiple PCs, each with their own copy of data. The two issues with this is
1. Increased memory usage -- each logged in user adds a significant memory overhead
2. Need for frequent refreshes -- so that all users "see" each others changes frequently.

Is there a means by which different logged in users can share the same persistence context ? (SFSBs using same PCs.) That will solve both these problems.

Thank You

Definitely NOT!

PCs are not supposed to be shared between users. If this is causing you problems, it means that the scope of your PC is too long.

Thanks for your reply. May I ask for ideas as to how such a system can be implemented ? (other than an in-memory DB) Should I look at JBoss Cache ?
