project has been created to develop JSR-223 engines for other languages and useful, demo applications that use scripting.
Just added two more script engines to http://scripting.dev.java.net.
jstScriptEngineFactory function to create javax.script.ScriptEngineFactory
for these engines.
It should be possible to use the jst and ejs engines with Phobos web application framework. [though I am yet to test that part!]
would be implemented as a translater that translates js2 to js1 (atleast to startwith).
