title: Servlet init method override necessary
body: <p>In a Servlet, I send initialization data through web.xml's init param tags. Why do I need to override init method to read the parameters, I can retrieve the values through <code>getServletConfig().getInitParameter("someName")</code> in my <code>doGet</code> method !</p>
  
  <p>Also, same with config, I can access the initialization parameters with this method : <code>request.getServletContext().getInitParameter("xyz");</code></p>
  
  <p>Why would I need to override the init method, and make sure the superclass config object is set as well etc etc?</p>
