Sun & Zend push scripting for Java

Is this related to JSR 223: Scripting Pages in Java^TM Web Applications (Via Aaron Johnson)?

My question is, what does this add to what Jython already gives us? You can already use Java classes in Jython, or subclass them, use Jython classes in Java, write taglibs and servlets in Jython, you name it.

See jPublish for a nice example of what you can do.

... and a hearty breakfast, and I feel like a new blogger. I'm not limping any more, either!
