getInitparameter

i want to use getInitParameter in a simple java class .... how do i do that ?

i tried to implement ServletContext

and then wrote the code:

user = getInitParameter("user" );

which resulted in the following exception :

java.lang.UnsupportedOperationException: Not supported yet.

Looks like your server doesn't support your code.
What server are you using?

I m using apache tomcat6.0

How are you sure that the posted statement caused the error?
Did the error message show where in the server was it thrown?
