data synchronisation - java server side or www server side?

[Thor]

I develop the application, which consists of the following:
- java server module (database connection, query execution, data update)
- www server module (www clients handling, data exchange with java server)
- many www clients (changing data, and need to have all data updated, so
synchronisation is required)

The question is:
To decrease the need of working with database and network load, where should
I keep
synchronised data taken out of database? At the java server side or at the
www server side?

Ever heard of Entity EJB's - they are actually server side caches of
data and the app server handles the synchronization etc.
