why do you use jBPM 3.1.4? There is a 3.2.x version and already even a 4.0 version. And yes, jBPM 3 runs great on Tomcat, 3.2 even better than 3.1. You *cannot* run the JBoss version on Tomcat since there are some differences, but those are described in many places (including the wiki) So for us to be helpfull, you have to provide e.g. errors/stacktraces etc, since it should work.
