You could either do a client-side response.sendRedirect or a server-side RequestDispatcher.forward (or include). The latter will preserve request information and attributes (which are lost when doing the former).

Let's say that you have a JSP page that sends a String conatins the name of the servlet to go to.
Your first serlvet receives this request, and it can have this code to decide the next servlet to go:


Hope it helped...

It really goes without saying, but silently ignoring exceptions is of course something you should almost never do, and definitely not here.

i think we can also use Query String!
