Today I ported the old Cocoon app to a fresh build of eXist, and got everything working. There are two or three little niggles to sort out, but basically everything is up and running. In the process, I've cleaned out a whole pile of obsolete code, cleaned up a lot of things, and simplified a bit. Another few hours and we'll be ready to deploy this as a replacement for the current app, which is pretty flaky sometimes, and which I suspect is responsible for the death of Tomcat once in a while.

Notes for future ports:

• Don't forget to put any jars you created into WEB-INF/lib.
• Edit controller-config.xml to set up your "/site" location for the app code.
• There's still a bug with the passing of duplicate parameters into XQuery functions. I suspect the add-parameter thing is unnecessary, and params get passed through automatically -- have to test this.
