Answer Posted / amit singh(mca ,niet)
servlet config is a configuration object used by the
servlet container to pass information to a servlet to a
durimg intialization ,before calling the service method to
a request it calls the init(servlet config) to intialize
the servlet ,at this time it loads all the parameter the
servlet neede, if you need that some parameter only has
relation with the servlet not the whole webapplication you
should to go with servlerconfig ,we use it in
deploymentdescriptor,if you want those information those
you want to use for whole application in which many servlet
so use servletcontext
caution is that :-try to not use servlet context in web
application becaz they are not thread safe
and in deploy ment descritor you use like that:-
<web-app>
<context-param>
<param-name>............<param-name>
<param-value>..........<param-value>
</contextparam>
<servlet>
<servlet-name>.............</servlet-name>
<servlet-class>..........</servlet-class>
<init-param>
<param-value>..........</parm-value>
<param-value>........</param-value>
</init-param>
</servle..
</web-ap...
i think u got the right answer ,and best of luck
