At the application level (in other words, inside your servlet) you can only do
things that are defined in the API of ServletRequest and HttpServletRequest. That
means you can modify request *attributes*, but not request *parameters*, or any of
the other things that you can "get" but not "set".
In the servlet 2.3 API, there is a new advanced programming technique called
filters which would let you "wrap" the incoming request with your own custom
implementation, and you could therefore do things like this in a Filter. But, even
in a servlet container supporting 2.3 you could not do this inside your servlet --
only in a filter.

Two things will help this a lot:
* Ask on-topic questions, after doing basic research in the
archives. (I don't know if you are one of the people that asks
questions about JavaScript or JDBC here, but you'll never
get an answer from me on that stuff here).
* Create a new message, instead of replying to an old one and
changing the headers (convenient because it picks up the
mailing list address for you). Like many people, I have my
mail reader set to present messages in "threaded" order. When
you reply to an existing message, that causes your message to
be nested inside a thread, instead of being sorted at the top level.
This makes your message much less visible, and more likely
to be missed, even if it is on topic.
That all being said, people who answer questions on mailing lists like this are
volunteers, doing so of their own free will and accord. You should appreciate help
when it is given, rather than resenting when it is not.
