Hi Jhanavi,

Difference between ServletConfig and ServletContext ?
ServletConfig is used to fetch the application specific data as the Initial parameters required for an application. Whereas ServletContext is used to get other details as to the applicatoin and server properties.
ServletConfig Object is passed in init() method which is further passed to the HTTPServlet Class.

Difference between server.xml and web.xml ?
Server.xml have the properties set which are required by the server as to the Cache size or some other properties, whereas web.xml contains properties specific to a web application.

Thanks,
Rahul Juneja
