virtual html file

I have a servlet which generates an html formatted entry from a
database.
It currently accepts a URL like this:-

http://www.trade-submit.com:8001/t?8154082

I would like the URL to be indistinguishable from a static html file.
e.g

http://www.trade-submit.com:8001/t/8154082.html

How can I do this?

The reason is the search engines don't seem to like the "?" in the URL.

I don't want to actually generate static files since I want to give a
genuine live version
of the data when the user uses the URL (so my servlet must be called).
