You can also check out the JBossESB project where we already did the integration.

I think it was something to do with the move to using the JCI interface. I can't be sure but one of the Drools guys could clarify it. It's no big deal to use Janino though. You just need the janino jar files deployed in your .ear and the classpath set correctly.

Hello Paul, I'd be interested to know what problems you encountered.
We're deploying Drools + Eclipse compiler in Tomcat 5.5 (and have been
since 3.0), and to my knowledge we don't have any issues with this
combination. Is there something waiting around the corner for us?
