servlet context is used if u want some values which must exist for the life time
of the application. A servlet config object used by a servlet container to pass
information to a servlet during initialization.The ServletContext object is
contained within the ServletConfig object, which the Web server provides the
servlet when the servlet is initialized.

ServletConfig and ServletContext are interfaces as part of javax.servlet

ServletContext is associated with an application.ServletConfig is associated with a particular Servlet.The webcontainer maintains only one context object for one application and multiple number of config objects.config objects are like localparamenter and context object is like global parameter.

hello

ServletContext: Defines
a set of methods that a servlet uses to
communicate with its servlet container,
for example, to get the MIME type of a file,
dispatch requests, or write to a log file.The
ServletContext object is contained within
the ServletConfig object, which the Web
server provides the servlet when the servlet
is initialized

ServletConfig:
The object created after a servlet is instantiated
and its default constructor is read. It
is created to pass initialization information
to the servlet.

hello

1)

Parameters defined in the ServletContext are visible for all servlets

Where as parameters defined in the ServletConfig are visible to the servlet where it has been defined .

2)

ServletContext has application scope wide

where as ServletConfig has Servlet scope

ServletContext has a life time as that of container.,
