Hi Gaminda,

   What you can't do in J2EE containers is to access the filesystem directly. Doing a getResourceAsStream() as you are doing is allowed, specially because your drl file may be inside the application jar/war/ear. If you are having a NPE, the problem is that the container is not finding your file in your classpath, so what you need to do is to fix the classpath. The strategy, though, is a valid one and works.
