It's certainly not a bad idea to grab a JSTL book, but the spec itself is quite
readable and full of good information:
http://jcp.org/aboutJava/communityprocess/final/jsr052/
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
I have a c:forEach where "items" refers to a Map, and "var" refers to
the current Map entry.
The value for each Map entry is an array. How do I switch on the length
of this array? I tried this:
But I get a syntax error; it says I supplied the "." operator with an
index value of type "java.la
Thanks again.

How can I refer to the index of the current iteration with c:forEach
(analogous to the indexId attribute to logic:iterate)?
Thanks,

I could use some Struts-EL/JSTL tag help, please.
I have a Map with each entry having a String as the key and a bean array
as the value.
I need two iterations, one nested inside the other.
For the outer iteration, I want to iterate the keySet of the Map. I
don't know what the keys are going to b
