Thanks for posting your query here in the beginners forum, however, please don't cross post your questions to multiple forums, most of the visitors here read in many of the forums and it is frustrating to see the same question repeated over and over - you have a better chance of gettng a correct and timely answer if you post it to the most appropriate forum instead of using the shotgun aproach and hoping you'll hit something.
I'm going to closs this topic in beginner. Actually you might get a better response in 'distributed
java'.
