Usage

From source file:MyServlet.java

public void doGet(HttpServletRequest req, HttpServletResponse res) throws ServletException, IOException {
    try {//from ww  w.  j a v  a 2s .co  m
        // Get a reader to read the incoming data
        BufferedReader reader = req.getReader();

        // Get a writer to write the data in UTF-8
        res.setContentType("text/html; charset=UTF-8");
        //PrintWriter out = res.getWriter();
        out = new PrintWriter(new OutputStreamWriter(res.getOutputStream(), "UTF8"), true);

        char[] buf = new char[4 * 1024]; // 4Kchar buffer
        int len;
        while ((len = reader.read(buf, 0, buf.length)) != -1) {
            out.write(buf, 0, len);
        }
        out.flush();
    } catch (Exception e) {
        out.println("Problem filtering page to UTF-8");
        getServletContext().log(e, "Problem filtering page to UTF-8");
    }
    out.println("Done");
}

        // Read and write 4K chars at a time
        // (Far more efficient than reading and writing a line at a time)

        int len;
        while ((len = reader.read(buf, 0, buf.length)) != -1) {
