I am unfamiliar with JBoss Drools so I may be way off base with all this so please bear with me! I'm trying to deploy Drools 4.0.0 and the BRMS on WebLogic 9.2 for evaluation purposes. I have the drools libraries and the drools-jbrms.war file. The libraries I place in the CLASSPATH and the war file I deploy to WebLogic. When WebLogic is started I get the error: Deployment Exception[Deployer:149233] ..... ...... An unexpected error during deployment process... ...... The security realm weblogicDEFAULT does not support application versioning...... ...... When the deployed Web Application is started a NULLPOINTER Exception results. There's no weblogic.xml deployment descriptor so I tried to create a role and user for the deployment but have been unsuccessful so far. Unable to find ANY documentation on all this stuff! Can the BRMS even be deployed on WebLogic 9.2? Am I missing something? Any help would be much appreciated.
