Because getInitParameter() was invented before contexts ever existed. tim.
RE: init params
I used to have similar problems as Russ - IMHO the naming of ServletContext
is wrong - the context is the web-application and not the servlet that's
returned by getServletContext. Obviously the powers who created the API cut
the naming of the function short - getContextServletIsIn - is what they
meant.
The grammatical construct "SomethingContext" usually is considered to name
the Context - which to repeat myself is the web app. ServletConfig contains
the parameters in the Context of the Servlet
Wish Sun would reconsider the naming of some of these classes and methods
...

Russ:
The first two methods...
* getInitParameter(String):String
* config.getInitParameter(String):String
both reference the ServletConfig.getInitParameter(String):String method.
This
returns configuration information specified by an element
within a
definition.
The other method...
* getServletContext.getInitParameter(String):String
references ServletContext.getInitParameter(String):String. which retrieves
parameter values from the element of a definition.
Check out the Servlet API JavaDocs or specification docs for more info.

RE: init params
Thanks for the quick posts.
Stupid me, I thought getInitParameter would always be for init-params.
I wonder why...
getServletContext.getInitParameter(String):String
is not
getServletContext.getContextParameter(String):String ?
not that it matters.
Thanks again.

Re: init params
You have given init parameter to the servlet thats the reason your first two
statements given correct result. The thrird one looks for the context
parameter which you haven't set. Refer the difference between the
ServletInitParameter and the Context-Parameter.
For contextparameter you have give
contextP
ContextValue
