[rules-users] Integrating DROOLS in J2EE...

[Paul Smith]

I don't know of any tutorials but I've been running Drools and JBoss
together with a MySQL database and EJB3 for about 18 months now. Currently
on Drools 4.02 with JBoss 4.2.1GA. It all works pretty well except for for
the need to use the Janino instead of the Eclipse compiler. There's
something to do with Tomcat that doesn't play nicely with the Eclipse
compiler. This was an issue way back when I was using Drools 3.2 (it's a
tomcat issue not a drools issue). It may be ok now but I've just stuck with
Janino because it works. My deployment is really more of an SOA approach
with Drools kept in the EJB tier and nothing in the web. I don't use any
struts validators and let Drools do it all via the service calls. The only
thing to watch is classpaths and ensuring you don't have incorrect versions
of the jars being picked up. Using EJB3 in conjuction with Drools works
really well because the entity objects can be thrown straight at Drools.
