InputStream is = getServletContext().getResourceAsStream(file);

public void doGet (HttpServletRequest request,HttpServletResponse response) throws ServletException, IOException
{
final Logger fLogger =
Logger.getLogger(HelloWorldServlet.class.getName());
PrintWriter out;
String title = "Simple Servlet Output";
// set content type and other response header fields first

response.setContentType("text/html");
fLogger.finest("this is finest");
fLogger.finer("this is finer");
