    NullPointerException in Interest example

      Hi everyone!

      I deployed the interest example successfully. Now I'm trying to run the client on the same machine, but fail with the following exception:

      java.lang.NullPointerException

      What could possibly be the reason for this?

      Thnx a lot!
