Hi,
       Here is my code in which we able to get an image anywhere on
applet by using mouse click and someother functions.Here we got a
JoptionPane by giving rightclick.But instead of that we need to call a
jsp tree structure in new window by giving right click. I hope you will
help me in next mail by giving appropriate code for getting jsp tree
structure .

                    Thanks for ur help.

Code:
