Servlets and ServletConfig problem

I tried working with Servlets ServletConfig. As I understood the
GenericServlet
gets the parameters automatically and using getServletConfig() brings
the config.
Now I have a servlet that extends from HttpServlet.
in it I have the init() method and in this method I call the
getServletConfig() but I get
a ServletConfig instance with no parameters !!!
What am I doing wrong ?

The parameters are set in the web.xml file descriptor.

<context-param>
<param-name>telephone</param-name>
<param-value>1234</param-value>
</context-param>


Now the problem with the getInitParameter() is that it doesn't bring the value
of "telephone" for example.
Furthermore the :
servletConfig.getInitParameterNames().hasMoreElements()
retruns false !!

There is a forum exclusive for Servlets. I feel that this question should have been asked there.

You are setting the values to <context-param> tag. Which means you can access there variables by getting a handle on your Servlet Context and calling getInitParameter("telephone").

This is what you should have in your servlet mapping to retrieve the parameters through your getServletConfig().getInitParameter("telephone")
<init-param>
<param-name>telephone</param-name>
<param-value>1234</param-value>
</init-param>

Hope that helps
