Hi Ian, I followed the steps you aforementioned and it worked fine ! (I had to fix couple of bugs I had in the code). This is Wonderful. It gives me the asking resource if it is there. Unless says resource not exists. I tested it having Cassandra running in back ground. I will start a new thread to discuss on how to proceed with the rest of the impl.
Thank you very much :-).
