YES,There is some difference,when we deploy the web
application the web container will create the Context
object and when we load the servlet class then container
will create config object,so for each web application web
container will create one servlet context obj and for each
servlet web container will create servlet config object.
Generally we use this objects to avoid the hardcoding,we
declare this variables in deployment descriptor,we declare
context parameters under web-app tag so that all servlets
can use this parameter values ,and config parameters under
servlet tag so that only specific servlet can use this
parameter values,in simple way context object is like
global object and config obj is like local obj.
