Returning an HTML/XHTML file from servlet

Question

I've seen servlets examples, they're something like this:

 public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        PrintWriter out = response.getWriter();
        out.println("<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.0 Transitional//EN\">");
        ...
    }

My question is, instead of the code, can I return an HTML page? I mean, something like this:

 public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
            PrintWriter out = response.getWriter();

            SHOW(FILE.HTML);

        }

Thanks!!! ;)

You need to use a RequestDispatcher and forward the request. Search around on the site for servlet forward to jsp or look on our servlet wiki page. — Sotirios Delimanolis

It seems that you're new to servlets in general. I recommend to check out our servlets tag wiki page. Put your mouse on top of [servlets] tag which you put on the question until a black box shows up and then click therein the info link. Other tags (may) have similar wiki pages. — BalusC

By the way, returning a XHTML file plain vanilla makes no utter sense. It has no value for webbrowsers. Just make it a HTML file. But that's a different subject. — BalusC

@BalusC I've started with jsf 2 weeks ago, with webServices 2 days ago and yesterday with servlets. You can laugh at me all you want ;) — dak

There are a few different ways you could do this:

Forward the servlet to the path where the HTML file is located. Something like:

RequestDispatcher rd = request.getRequestDispatcher("something.html"); rd.forward(request, response);
Send a redirect to the URL where the HTML is located. Something like:

response.sendRedirect("something.html");
Read in the contents of the HTML file and then write out the contents of the HTML file to the servlet's PrintWriter.
