Need a help about init action in HttpServlet

Question

I provided a new class MServlet which extends HttpServlet.
I want to use the Mservlet class for my all servlets. My Mservlet must do some thiggs.
For example i have a class:
public class ListNews extends MServlet
So now i need some things would be done automaticaly. For example
response.setContentType("text/html;charset=windows-1257"); must be setted
that i do nor need to write this line in all servlets?
How i can do it?
If i am using public void init method in servlet and put there the string
response.setContentType("text/html;charset=windows-1257");
This does not work
Thanks

Just a minor switch with the previous post...
Use the MServlet to implement the doGet and doPost methods, make them final so that the subclasses can override them.
Provide a 'responseSetup' method that sets things that you want.
Provide your own 'doGetWork and doPostWork methods that the subclass overrides with its own stuff:
public MServlet extends HttpServlet {
  public final void doGet(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {
      responseSetup(response);
      doGetWork(request, response);
  public final void doPost(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {
      responseSetup(response);
      doPostWork(request, response);
  //Default implementation does the same as HttpServlet.doGet()
  public void doGetWork(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {
      super.doGet(request,response);
  //Default implementation does the same as HttpServlet.doPost()
  public void doPostWork(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {
      super.doPost(request,response);
  //Do your init stuff here
  private void responseSetup(HttpServletResponse response) {
      response.setContenType("text/html;charset=windows-1257");
}Then subclasses would use doGetWork and doPostWork like notmal HttpServlet subclasses would use doGet and doPost...
