How to integrate Geronimo's transaction manager in Tomcat?

Question

Does Geronimo provides a standalone transaction manager? And if it does, is it possible to use it in Tomcat?

Answer 1

Apache OpenEJB is embedded implementation of Geronimo EJB container that includes Transaction Manager. OpenEJB can be embedded into Tomcat which is one of its intended usages.

Answer 2

If you specifically want the Geronimo TX manager, then see @grigory's answer.

If you're just looking for a free, open-source TX manager, though, the JOTM is a TX manager that embeds nicely inside Tomcat.

I should ask why you need this, though. If all you need to do is JDBC transactions against a single DataSource, then you don't need a TX manager. You only need one if you want to do full JTA transactions.

Answer 3

AFAIK, Geronimo uses Jencks that can be used standalone. But I can't say it's heavily documented. I'd rather consider using Atomikos or JBossTM.
