Olu,
I'm using the same HttpServer, and I always get a Error:404 (If I forward to a
servlet) or Error 400 (If I forward to an HTML file)
Could you send me some sample code as well as the location of the JSP called by
your servlet?

I had no problem with it! But I am running the mini HttpServer that comes with
the jsp1.0 distribution.
