Thanks for that, but I don't see how it will help. If you look below it is the jasper2 that is causing me grief, which is essentially the same as yours.
How long does it take to precompile the JSPs. Is it several JSPs per second or several seconds per JSP? My JSPs take over 20 seconds to compile interactively, which would make precompiling all of them infeasible except for a nightly build. I'm surprised that your script needs those package rename hacks. Feels like precompiling into Tomcat's work area should be built in, bin/precompileJsps.bat|.sh.
