Простой возвращатель html файлов

Задачка была сделать так, чтобы по урлу http://127.0.0.1:8080/context вытаскивалось содержимое папки context корня проекта (html/css/js). Причем если я соберу war И задеплою на сервак, то корнем проекта будет считаться корневая папка вебконтейнера. Если запрашиваемого файла нет, создаю новый.

Велосипед короче очередной. Но надо было быстро.

Вот архив.

Вот основной сервлет

package com.apofig;

import javax.servlet.ServletException;

public class SampleServlet extends HttpServlet {

    @Override
    protected void doGet(HttpServletRequest req, HttpServletResponse resp) {
        try {

            String context = req.getContextPath();
            if (context.startsWith("/")) context = context.substring(1);

            String path = req.getServletPath();
            if (path.equals("/") || path.equals("")) path = "/index.html";

            String fileName = context + path;
            File file = new File(fileName);
            if (!file.exists()) {
                file.createNewFile();
            }

            String mimeType = getServletContext().getMimeType(file.getPath());
            resp.setContentType(mimeType);
            resp.setContentLength((int) file.length());

            if (mimeType == null) {
                resp.setStatus(HttpServletResponse.SC_INTERNAL_SERVER_ERROR);
                return;
            }

            write(resp, file);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    // thanks to http://stackoverflow.com/questions/8623709/output-an-image-file-from-a-servlet
    private void write(HttpServletResponse resp, File file) {
        try {

            try {

                out = resp.getOutputStream();

                // Copy the contents of the file to the output stream
                byte[] buf = new byte[1024];
                int count = 0;
                while ((count = in.read(buf)) >= 0) {
                    out.write(buf, 0, count);
                }
