How to execute a dynamic JSP from a Servlet WITHOUT sending it to disk first ?

[L.Fernando]

Hi All,
I have the following problem:

Based on some database data, one Servlet dynamicly generates an JSP page
text inside an string buffer.

The question is:

How to execute that "page" without having to write it to disk before
dispatching it ? I mean, how to send that string buffer (with my "page"
inside it) directly to the jsp interpreter servlet ?

Any help will be welcome !

Thanks in advance,

Fernando.
