Consider a frame page with Applet on left and jsp on right frames. When a user right clicks a node on JTree I have to pass that value to the jsp page. e,g UserName is visible on the node and when u right click a popup menu opens and u want to edit the user information. How can I send UserID to the jsp page. The userid can be send to the jsp page using query string. How can I store the UserID in the node? I have username on the tree node and I dont know what to do next? Any help will be higly appreciated
