[rules-users] Drools5 in tomcat 5

[Jervisliu]

Examples below shows how to use drools Camel integration. With Camel 
integration, you can host drools rule engine as a Camel service. The 
service can be based on Web services, REST, JMS or whatever capabilities 
Camel offers.
http://anonsvn.jboss.org/repos/labs/labs/jbossrules/trunk/drools-pipeline/drools-camel/src/test/java/org/drools/camel/component

You can also use Drools pipeline to expose a drools rule engine as 
service. For example, example below is exposing Drools through JMS:
http://anonsvn.jboss.org/repos/labs/labs/jbossrules/trunk/drools-pipeline/drools-messenger-jms/src/test/java/org/drools/runtime/pipeline/impl/SimpleJmsMessengerTest.java

If you do a google search, you can also find some nice docs on how to 
use drools-pipeline to expose drools engine as web services etc.

Hope this helps,
Jervis
