I didn't see Jython support in Spring 2.0 M2. So I wrote a prototype. http://yanweng.blogspot.com/2006/02/prototype-of-jython-scriptfactory-for.html
It's not perfect because I have to use "naming convention to help the scriptFactory instantiate the Jython Object.

The idea of using Spring's Script Factory support is:  We can write most of the application features using Jython. At the same time, we gain all the benefit that Spring provides. If performance becomes an issue, we just need to rewrite the "bottle neck" part using Java.

Any suggestion on improving the Jython ScriptFactory?
