how is it different from the helma? I found helma(helma.org) quite mature. Compare http://appjet.com/learn-to-program/lessons/lor http://appjet.com/learn-to-program/lessons/lor to http://helma.org/docs/guide/framework/ http://helma.org/docs/guide/framework/ Is there anyone who has used helma extensively can comment on this?
