Transaction and jsp

[erikture]

Hello!

I am using Jboss 3.06.
I have a number of stateless session beans accessing a number of CMP 2.0 entitybeans. Both the session and entitybeans has the transaction attribute set to Required.

I am accessing the session beans from jsp pages.
My question is when is the transaction created?
Is there one transaction for each jsp page or one for each call to a session bean method?

If I want to calls to session bean methods to be in the same transaction, do I then have to use the UserTransaction class or not?

Yes.
Or you can use a filter then configure
which urls require a transaction.

e.g.
http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/jboss/applications/forums/src/main/org/jboss/forums/web/TransactionFilter.java?annotate=1.4

WARNING: Using a transaction in a servlet/jsp
can lead to longer running transactions because
flushes to the client can delay the commit.
