Andrew,

2 things. First, is there a good tag reference (similar to the Struts
docs) for the JSTL tags online? I've never worked with JSTL before.

Second, I've looked at the stxx web site, and it looks like an
intelligent system.... on the other hand... it looks like it might add a
good chunk of development time:

BEFORE:
1) Create JSP to display code

AFTER:
1) Make All actions extend Stxx Action
2) Implement saveDocument for all actions
3) Create XSL stylesheet for all actions

This seems like a lot of additional steps, with the increased debugging
issue of having to compile the action and restart the webapp for each
change.... JSPs can be edited live and reloaded to see the changes.  On
the other hand, Stxx adds in a few new features (like delivery to a cell
phone, XML-output to use with an XML Web Services app, etc). Have you
used it? Do you like it?

Thanks,
Aaron
