title: What is the servlet's init() method used for?
body: <p>When I decompile the GenericServlet and check the  init() , I see the following code .</p>
  
  <pre><code>public void init(ServletConfig servletconfig)
      throws ServletException
  {
      config = servletconfig;
      init();
  }
  
  public void init()
      throws ServletException
  {
  }
  </code></pre>
  
  <p>What is the init method actually doing here ? Am I missing something ?</p>
