:-)  Yeah, JSTL is progressing in a way that might very well address needs
you run into.  If not, scriptlets might still be appropriate for small
applications, although for larger ones, I'd recommend developing a custom
tag library.

Yeah, this more-detailed documentation will be part of the next release.  
The new expression language, in particular, is much more flexible than the
old one.  It supports booleans and arithmetic, and it also takes care of
type-conversions behind the scenes so that you never have to think about
