Rafael, Thank you very much for response. Unfortunately I could not proceed with the solution as described in the URL's provided. Solution provided in the example was for ear files. I could not locate a solution in case of war file deployment. Also I would like to mention that if I remove Drools library from the class path, I am able to run at least my current web application. Otherwise, if the drools library is in the class path I am unable to run even the exisiting web application. Thanks G.
