Re: Forward problem (JSP)

Set up the choice as one of several different HTML controls, e.g., submit
buttons. Use a <form> tag, naturally, with method set to "post".

<form name="x" method="post" action="/home">
   ...
   <input type="submit" name="destiny" value="Go to A" />
   <input type="submit" name="destiny" value="Go to B" />
</form>

and map the "/home" target to a controller servlet that decides where to forward:

public class Control extends HttpServlet
{
   protected void doPost(
       HttpServletRequest request, HttpServletResponse response )
       throws ServletException, IOException
   {
     String target;
     String destiny = request.getParameter( "destiny" );
     if ( destiny.equalsIgnoreCase( "go to a" ))
     {
       target = "A.jsp";
     }
....
     RequestDispatcher rd = request.getRequestDispatcher( target );
     rd.forward( request, response );
   }
}

Exceptions and package imports omitted for brevity.
