I suppose the other possibility is that you don't have a "resources/" directory on your CLASSPATH at compile-time, when you end up building your JAR for submission to the Storm cluster. You could verify this by inspecting the JAR you are about to submit to the nimbus. Do something like this:
mkdir foo mv foo.jar foo/ cd foo unzip foo.jar ls resources/ If you have a resources/ directory, then your JAR is being packaged up correctly. If you don't, that explains it. This is described in the "Packaging your stuff" section in the multi-lang protocol <https://storm.incubator.apache.org/documentation/Multilang-protocol.html> docs.
