Java servlets: how to display a page?

I'm using a Java Servlet to do some work (validate user login, update session values, etc.) and I want to redirect to an existing JSP page when I'm done. How do I do that?

Apart from using HttpServletResponse.sendRedirect() , you can also set the http response header and status code to SC_MOVED_PERMANENTLY (301) or SC_MOVED_TEMPORARILY (302) 

response.setStatus(HttpServletResponse.SC_MOVED_PERMANENTLY);  
response.setHeader("Location", "http://www.xxx.yyy/");

also to sendRedirect take a look at 

 request.getRequestDispatcher("/foo/foo.jsp").forward(request, response);

redirect is useful then you changed some information (e.g. made a post in the forum) so redirecting will prevent double posting.
