RE: [ANN] JavaServer Pages, 3rd Edition (O'Reilly)
I would rather see both JSP2.0 and JSTL1.0 reference book in one - because it is most likely you would be using them together and that would spare you from having one more book on your bookshelf :) thanks, Marina -Original Message- From: Henri Yandell [mailto:[EMAIL PROTECTED] Sent: Wednesday, December 24, 2003 2:51 PM To: Tag Libraries Users List Subject: Re: [ANN] JavaServer Pages, 3rd Edition (O'Reilly) I'd like to see a JSTL only pocket reference, but I'm not sure what the critical mass page-wise is for such a thing.

You're with the right publisher and it sounds like the book has the content in it to make it easy. Yes, that's an idea. I did a pocket reference for JSP 1.1 a couple of years ago (roughly 80 pocket-size pages). Would it make more sense to do separate JSP 2.0 and JSTL 1.1 pocket references, or one that combines JSP 2.0 and JSTL 1.1? I'll check with O'Reilly after the holidays.

The one from Manning's book (appendix A) isn't really quick enough for me (Too many pages). I find I'd really like a 1-2 page summary of EL and the JSTL tags. I keep meaning to do one up myself, but of course work projects keep taking priority. I'm not sure what you'd like to see covered by a 1 - 2 page summary, but in terms of summaries, my book has 3 page overview of the JSP EL (with tables for all operators and implicit variables) in one chapter, a 3 page intro to JSTL in another chapter, plus appendixes with concice descriptions of all JSTL custom tags and classes and the JSP EL syntax, variables, and type conversion rules. The EL and JSTL tags are also used extensively in realistic examples throughout the book.

RE: How to maintain the selection items in the Select using the j akarta.apache.org input tag library
you could also try using TreeMap - it is ordered. You might also consider writing your own comparator for keys if you don't like the default one Marina -Original Message- From: Martin Cooper [mailto:[EMAIL PROTECTED] Sent: Tuesday, November 04, 2003 7:10 PM To: Tag Libraries Users List Subject: Re: How to maintain the selection items in the Select using the jakarta.apache.org input tag library On Tue, 4 Nov 2003, Kimberly Clary wrote: I want to have the items in my Select list showing in a certain order.

HashMaps and Hashtables are unordered collections. The order in which you add elements to them does not make any difference at all. If you need to preserve that order, you may want to take a look at the SequencedHashMap class in the Jakarta Commons Collections package. -- Martin Cooper Can someone help me?

EL expressions are not evaluated
Hi,
Sorry if this question was asked already...
I am trying to write a simple test web application using JSTL and
encountered the following problem:
JSTL core tags are working fine (like c:out ..., c:forEach...) but the
EL expressions are not evaluated. I do use the c.tld file - it is in my
app's WEB-INf directory. Below is a simple test page that demonstrates the
problem:
%@ taglib prefix=c uri=http://java.sun.com/jstl/core; %
html
head
titleJSTL WISS Preview/title
/head
body bgcolor=#FF
jsp:useBean id=directory
class=test_wiss_JSTL.WISSDirectoryDataBean /
br
Total number of Files (JSTL): c:out value=${directory.totalNumFiles}/
br
Total number of Files (JSP):
jsp:getProperty name=directory property=totalNumFiles/
br
c:forEach var=i begin=1 end=5
c:out value=${i}/br
/c:forEach
c:forEach var=file items=${directory.fileList}
c:out value=${file}/br
/c:forEach
/body
/html
The result (in the browser) is:
Total number of Files (JSTL): ${directory.totalNumFiles}
Total number of Files (JSP): 2
${i}
${i}
${i}
${i}
${i}
${file}
So, as you can see, the c:xxx tags work correctly , the usual JSP tags
work correctly also and the bean's totalNumFiles value is shown correctly
too, but when I try to show the same value using the EL expression
(${directory.totalNumFiles} ) - it does not work. Nor does a simple integer
value ${i} - not a bean's property...
It seems I'm missing something very obvious - just cannot see it just yet.
Any ideas?
I use Tomcat5.0.12. I did try to include the JSTL's jar files (standard.jar
and jstl.jar) into my web application's WEB-INF/lib directory, even though
they are in the $CATALINA/commons/lib - it did not help.
Thanks,
Marina

Try adding
?xml version=1.0 ?
web-app version=2.4
xmlns=http://java.sun.com/xml/ns/j2ee;
xmlns:xsi=http://www.w3.org/2001/XMLSchema-instance;
xsi:schemaLocation=http://java.sun.com/xml/ns/j2ee web-app_2_4.xsd
at the top of your web.xml. If you don't tell tomcat this is a 2.4 version
document it will not try evaluating EL expressions.
Also, don't double-include libs that are already in tomcat/common/lib in
your WEB-INF/lib since it can cause problems. There is no need for it
either. If you are using an IDE you might have to include just the path to
those libraries in the project settings
