No, it's actually only one webapp. It's a data file. Using a database

one synchronized class.

Have you considered creating a separate session bean that accesses
the file, and accessing that bean from the web-applications instead
of going directly to the file.

Preferably you can build some sort of transaction control on top of it.


Wouldn't a session bean have exactly the problem he's having now? There will be multiple sessions beans (one per user now, instead of one per webapp) and they'll still need to synchronize amongst themselves on one file?

Obviously, if there is one file per session, then this is an ideal solution, but I didn't read that in the OPs problem statement.
