I will not be hacking the JSP Engine to 1.1 or 1.2 - I only ever use
basic JSP and so won't ever need to do it. I'm not interested enough
to do it for anybody else.

Sure. It would be nicer if you'd used Kawa. But it still sounds cool.

I would be very interested in helping you do those bits. 

In GNUJSP the bit that is most creaky and in most need of a
substantial rewrite is the compiler. To be honest, I have to
consciously stop myself thinking about how it might be improved
because it's a big job and I don't have time to do it.

However, if you supply the compiler I think I can hack what is in
the current JSP Engine CVS to supply all the other bits.

How about it?

PS Do you still need the CVS module you've got at my site? (for
kopisusu)
