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. There are also plenty of web resources available: http://www.javaworld.com/javaworld/jw-02-2003/jw-0228-jstl.html http://www.onjava.com/pub/a/onjava/2002/08/14/jstl1.html http://www.onjava.com/pub/a/onjava/2002/09/11/jstl2.html http://www.onjava.com/pub/a/onjava/2002/03/13/jsp.html http://www.onjava.com/pub/a/pub/a/onjava/2002/05/08/jstl.html http://java.sun.com/developer/technicalArticles/javaserverpages/faster/ http://java.sun.com/developer/technicalArticles/Intl/MultilingualJSP/ etc. Quoting Erik Weber <[EMAIL PROTECTED]>: > Kris, once again you have helped me get my work done. bean:size did the > trick.
