Are you asking about read access or write access? And more importantly, why do you want to do this? There are multiple approaches, and some are more suited to certain scenarios than others.

actually what i meant was that suppose multiple users accessing same part in database(for write access),then will jdbc transaction support (autoCommit(),comit(),rollback().) will manage all that or i have to do other things also?

In simple i want to ask that there are various reads, locks, isolation levels etc.in database to prevent shared access.will all these get managed by using jdbc transaction support (autoCommit(),commit(),rollback()) in java program?
