Hi Casey,

Sorry, I have too many things for now - the web based build is going to
wait a bit. If you could check in the changes, great.( I hope you got the
commit access )

BTW, I have few ideas for the pooling in jasper34 ( I would like to make
the pool pluggable, and managed by the container ). Getting the code
generator to work is first, but I hope in few weeks to finally merge the 2
runtimes and make the changes, and I hope you can review ( or help
:-) some of it.
