Question

I developing this web app using jsp and servlets. I was wondering how to display results on same page as on from which the request was made. For example, usually what I do is that a request is sent from one jsp to a servlet and then servlet sends the response/results on separate jsp. I am want to show a database results on same page. How can this be done?..A code snippet would be appreciated. Thanks

Answer 1

Just set the necessary data in the request scope and use RequestDispatcher#forward() to forward the control to the desired JSP which in turn can generate the appropriate HTML based on the results.

request.setAttribute("results", results);
request.getRequestDispatcher("/WEB-INF/page.jsp").forward(request, response);

This is also demonstrated in the hello world examples in our servlets wiki page.
