Dear Arun,
please understand that we are all volunteers here trying to help you, so it would be nice if you could make it as easy for us as possible. In particular: think hard about which forum to use and don't crosspost; don't use email, so that others can benefit from the discussion, and before posting try to think about whether a single google search could already answer your question. See
http://faq.javaranch.com/view?HowToAskQuestionsOnJavaRanch for more ideas.
I deleted the duplicates in the other forums and will move this to our tools forum...
The soul is dyed the color of its thoughts. Think only on those things that are in line with your principles and can bear the light of day. The content of your character is your choice. Day by day, what you do is who you become. Your integrity is your destiny - it is the light that guides your way. - Heraclitus
