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.

<div>Hi everybody!</div>
<div>&nbsp;</div>
<div>Does anybody know where I can find good tutorials concerning DROOLS 4.0.3\J2EE integration?</div>
<div>&nbsp;</div>
<div>I will use an Oracle DB and JBOSS Application Server (4.0.5).</div>
<div>&nbsp;</div>
<div>Any help will be great!</div>
<div>&nbsp;</div>
<div>I hope I will get used to DROOLS as soon as possible so that I will be able</div>
<div>to help someone in this ML and not only making questions on it.</div>
<div>&nbsp;</div>
<div>Thank You anyway.</div>
<div>&nbsp;</div>
