Form Submit success response using servlets

I am submitting a form for file upload to a servlet but I don't know how to send a success event back to Javascript. I need to call a function after the servlet is successfully executed.

Just let the Servlet set a variable in request scope and let JSP generate the JavaScript code accordingly.

Servlet:

boolean success = true; // or false.
request.setAttribute("success", success);
request.getRequestDispatcher("/WEB-INF/result.jsp").forward(request, response);

JSP:

<script>var success = ${success};</script>

It will end up in webbrowser like

<script>var success = true;</script>

You know how to continue with this JavaScript, right? if (success) {} else {} and so on :)
