[rules-users] Error while upgrdaing drools version

[Mattias Nilsson Grip]

Hi Mohan,

I would suspect that this problem is caused by having two versions of Drools in classpath. Maybe rules are compiled with one version of Drools compiler and then attempting to run with a different version of Drools core.

JBoss ESB comes with an embedded version of Drools (in jbrules.esb). So if you are planning to run rules inside ESB deployments I would recommend sticking to that version. Otherwise you may have to use class loader isolation to make sure your deployment does not attempt to load classes from jbrules.esb.

Regards,
Mattias

Subject: [rules-users] Error while upgrdaing drools version

Hi folks,
I'm using JBoss 5.1.0 GA, Jboss ESB 4.9 and  Drool 5.1.0

recently i have  tried to upgrade all my entities as below.

*jboss-6.1.0.Final, jbossesb-4.11, drools 5.3.1.Final*

while i start app server i'm getting below error and still i couldn't trace
it. Is it because of compatibility issue or bug? I'm using same drl file as
earlier.
