Here's how I did it: 1. I successfully deployed jbrms and insurance webapp (both using Drools v 4.0.6) successfully to JBoss 4.0.5. 2. From the jbrms webapp, I modified the "Night Vehicle Place" technical rule, just change the sysout statement. 3. Rebuild the binary package. Recreate the snapshot deployment - InsuranceDemo. 4. Retest using the insurance url and see if the new version (Remember the sysout stmt change in #2.) of the rule will be picked up by the RuleAgent. Alas it did NOT. Now this is of course inside a container environment. What is strange though is if you tried to run the InsuranceCalculateTest which is a JUnit test it recognize the rule change immediately. Which I think should be the behavior exhibited on a container environment as well. Right?
