I think either JspServlet is wrong or your implementation of the
jsp-reader, don't you think? I would like you to try to use the
HttpContext in your jsp-reader to determine the context relative portion
of the src value.

I didn't ask you to change anything, I only needed an advice about that. I
need a relative to context path, because I have to pass that path to a JSP
servlet (any, not only Apache Jasper), otherwise it won't work.

I am using that method  now (thanks to Vadim Gritsenko who gave me the
hint). The JspServlet is not wrong - it works as expected by the
specification (Servlet ans JSP). The implementation of JSPReader is in work,
so it is possible to be wrong ;)

Btw, I tried to make my JSPReader Contextualiazable, but it seems that
contextualize method was never called. What's can wrong: a reader cannot be
contextualizable or I do something wrong?

Thanks for any help.
