Hellu,

I finally got the time to setup a configuration without Jboss, and I like to have some advice on the following design issues.

I was thinking about a combination of tomcat/jotm/hibernate. Configure jotm in tomcat like documented and let hibernate use it through a jndi lookup.

However I still have some uncertains about the design that have to found out. Here is one of them:
1) Why should I use Jotm ? I mean, I could just use the build-in JTA of hibernate. What extra does Jotm offer me and how does it behave ?


Is there a demo application that contains about the same items I am looking at (couldn't find it 123).

Please some feedback ?

A clarification: Hibernate transactions are not JTA transactions. Hibernate transaction only span the database connection underlying the session from which you got the transaction.

JOTM is a JTA and (I believe XA) compliant transaction manager. JTA is simply a generic transaction demercation API. It can be applied to any jta-based "resource manager" such as jdbc, jms, etc. And if XA enabled, it can even cordinate transactions between these various resource managrs.

OK, I got it.
