Hi, I have a simple process with a single task as  (1)Start==>(2)Hello Service Task==>(3)End.
The service task is a JavaDelegation class that is trying to refer an object exposed in another bundle. This object is referred inside the beans.xml below as helloService and I am getting the NullPointerException. Could someone help me if I am missing anything?
