Hi Sushant, thanks for your post. It's very helpful. We did the similar experiments. However your implementation is more thorough and the way to deal variable is better( just use a hardcoded instance variable for "noOfTrantisionsFromNode", and another one for "LIST_OF_EXECUTIONS") We'll look into your approach in details and will come back if any questions, Thanks Zengping View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4266236#...
