Java EE (Java Enterprise Edition) General Discussion

Hi.

I use ejb+glassfish+postgres in my project.
The project is a web application for finansial data transfering.
I have three DBs, long global transactions, serializable isolation level, container-managed transaction.

When i test the project with concurent threads, i get an exception: "ERROR: could not serialize access due to
concurrent update"

I read that when you get suck kind of error, your program must rollback current transaction and then reply this transaction.

what do i need to do to complete this transaction? :
1) rollback and reply transaction
2) maybe, the are other ways to reply transaction (for example: glassfish configurations, ....)
