Java / XSLT configuration project

Just wondering if anyone know’s if there are any Java / XSLT configuration project out there at the moment, open source or not.
I’m going to be developing a drag and drop interface to develop html page using java, xslt and xml. Instead of hand writing the xslt each time, I hoping to develop something where I’II have a couple of different templates that will be populated using Java and XML

Cheers in advance
