OK guys !
What is the best "FREE" servlet/JSP engine available
Note i want to be using idealy JDK 1.2,servlets 2.2 and JSP 1.1 eg the
latest versions.
However support for servlets 2.0,2.1 or JSP 1.0,1.1 is ok but i want to
use JDK 1.2

I agree this is a weakness. But the API tries to abstract servlet
developers from the details of HTTP, which is a good thing for those
of us who don't know much about it.

Welll... I don't think it says this exactly does it? Servlet
containers have always provided extra tools. Indeed any servlet
container supporting HTTP/1.1 and persistent connections MUST support
chunked encoding according to the HTTP spec so that's that.

Not so. The chunking layer doesn't need to know about the application
layer at all. See my chunked encoding class which is part of
GNU-Paperclips.

No.
We don't need to do this because it is not necessary for the app
layer and the chunking layer to communicate. It would also make the
API and implementation more complex.
