It's certainly not a bad idea to grab a JSTL book, but the spec itself is quite
readable and full of good information:

The only JSTL book I've even partially read is "JSTL in Action" by Shawn Bayern
and I have no reservations recommending it
Kris, once again you have helped me get my work done. bean:size did the
trick. I was looking over and over again for a JSTL tag or expression to
do this; I probably never would have thought of bean:size.
To complete the post for any other reader who is as suicidal as I am
after trying to figure
I guess the first thing to make sure you understand is that, when iterating over
a Map, the object exposed by JSTL via the var attribute is of type Map.Entry.
It's equivalent to doing a map.entrySet().iterator(). As for getting the size
of an array, Collection, or Map, use the tag.

OK, I'll take ANY WAY TO DO THIS AT ALL.
I have a c:forEach over a Map. The value for each key in the Map can be
an array of objects, or I can make it a List. I don't care at this point.
All I want to do is get the length of this array or List, before I start
iterating over *it*, during the curr
4 matches
