Hi,

I am using Hibernate v2.1.7 with Weblogic. I am using Weblogic's JTA, and at the end of each session(or EJB call) - I call session.flush() to synchronize the session with the database. However, what if an error occurs halfway through the synchronization - how can I rollback "flushing" the session, or the transaction? I am not using the Transaction API because I'm using Weblogic.

Thanks in advance.

When you have error, throw the exception to you layer where you have done the flush and catch that exception.

so you can avoid doing flush there in case of exception.

That is what I am doing, but for some reason, some inserts were still occuring into the database. I'll test again, I think I was doing something else wrong.

Thanks though for the verification!

And one more thing, you are not using your flush statements anywhere right ?
Remove all the flush statement and check.
If everything is all right at the end of your transactional block, it will make necessary changes and rollback if in case of exception.

Just give a try for this one.

What od you mean? When I am done with all the necessary changes, I call session.flush() to "commit" to the database. I read in the documentation that calling flush() is necessary in an EJB container (b/c I am not using the transaction api).
