in J2EE:

suppose that inside a J2EE transaction not just updates to the DB are preformed, but also some objects and primitive types are being changed.if the transactions fails to reach the commit stage for some reason, and a rollback action is performed would the initial value of the objects and primitve types be restored?

A transaction applies to the database and java objects that have effectively 'become' the database through CMP/BMP - not any other objects.

Transactions are related to db data, not your objects. You need to manage those yourself.
