1)  I want the contents of my HTML page display to refresh automatically based on a selection made by the user. I am using HTML + JSP.
 For Example:
   There are three radio buttons
           - Thesis
           - Non-Thesis
           - Software Engineering
   Drop Down Menu1          

If the user selects 'thesis' there should be one drop down menu appearing on the screen else there should be two drop down menus appearing.
  How can I do that?
2)  Also what function in JSP will allow my page to display one image if the mouse is placed on it and another image if the the mouse is not place on it?
I shall appreciate any help.
