How to retrieve value from web.xml in Servlet?

Question

I need to retrieve init-param value from xml to Servlet i used following code

    LoginServlet
    &         


        

Answer 1

um... it should work. Are you calling the code in LoginServlet? And the

<servlet-class>LoginServlet</servlet-class> 

is not in any package?

Answer 2

I can't see a single reason, why you have to override your init(ServletConfig sc) method, since you can always get your ServletConfig by calling your inherited getServletConfig() method.

System.out.println(getServletConfig().getInitParameter("jdbcDriver"));

Answer 3

If you have custom initialization work to do, override the no-arg init() method, and forget about init(ServletConfig). Is it ok to call getServletConfig() method inside the no-arg init() method? Yes, an instance of ServletConfig has already been saved by superclass GenericServlet.

It is always good to use packages for classes. It enables clear demarcation.
