EJB isolation level

Hi ,

I have a question on EJB isolation level TRANSACTION_READ_COMMITTED_FOR_UPDATE. My EJB has this isolation level and the oracle database i am connecting to has a default isolation level of READ_COMMITTED.

This EJB is used to generate a sequence. I sometimes encounter concurrency problems in that when two users request for a sequence number for the same TABLE , it ends up giving the same sequence number to both the calls.

How do I reslove this issue?

I would appreciate any inputs .

Thanks
Lavanya
