el in JSTL / JSP 2.0
Hi,
I am trying to introduce JSP 2 with Tomcat 5 (full source
below), and thus experimenting with the JSTL expression language in JSP
tag files (.tag). I am bemused as to why I cannot embed the expression
language within a JSTL tag thus:
c:forEach begin=${a} end=${b} varStatus=status
${status.count} br/
/c:forEach
Tomcat is really unhappy with this:
org.apache.jasper.JasperException: /WEB-INF/tags/wrapper.tag(13,4)
According to TLD or attribute directive in tag file, attribute begin
does not accept any expressions
org.apache.jasper.compiler.DefaultErrorHandler.jspError(DefaultErrorHand
ler.java:39)
the same code with c:forEach begin=1 end=5 varStatus=status
iterates 5 times with no trouble. I have the latest tld's from Jakarta,
status.count is displaying correctly.
Any thoughts please?
Thanks
Paul.

Re: maven repository
Felipe, I'mon vacation this week so you may not get many responses from me. I'll try to be breif. Quoting Felipe Leme [EMAIL PROTECTED]: Hi Mark, I'd like to upload all taglibs to the repository, but I have some questions: On Sat, 2004-02-28 at 12:12, Mark R. Diggory wrote: 1.) create a project directory for taglibs that looks like /www/www.apache.org/dist/java-repository/jakarta-taglibs/jars/standard- version.jar /www/www.apache.org/dist/java-repository/jakarta-taglibs/jars/jndi- version.jar /www/www.apache.org/dist/java-repository/jakarta-taglibs/jars/tag-lib- version.jar 1.Is /www/www.apache.org/dist/java-repository/ still the right directory that is synced to ibiblio? If so, where the taglibs from ibiblio came from (as that directory does not have any of our artifacts)? Yes, but, you should do all your work to setup the directory structure in a staging area like your home directory before placing anything into these directories. Have someone else whose done the process review everything prior to moving it into the repository. 2.Ibiblio already have groups for jstl and taglibs, but they have just a few jars. So, we have 2 options: a.maintain that structure b.put everything on jakarta-taglibs, removing these old files from ibiblio I opt for option b - the only problem is that if remove jstl and taglibs from ibiblio, it might break other projects that depends on them (I would still prefer that option, as those groups are crippled). I don't believe that removing something from java-repository actually removes it from ibiblio because of the rsync process. Yes, you should leave whatever is on ibiblio there at this time. 2.) for the last couple releases we should probibly just extract the jars from the tar ball distributions and generate md5's for them. Ideally, we should 'mavenize' the whole project. But for now, we can just generate/upload the MD5 files manually. thats fine. 3.) finally, a SNAPSHOT symlink and reference file should be generate which points to the latest release for each taglib: I read in some ASF list that we should not be providing SNAPSHOTs, only official releases. SNAPSHOT is different than unofficial release, SNAPSHOT referes to a link to the most recent release. an unofficial release is one that has the date as a version number, thus there can be SNAPSHOTS that point to official releases in the repository. Once you confirm my questions, I can write some shell scripts to populate our repository. Regards, Felipe Cheers, I'll be around next week if you need help, but I don't suspect I'll have time to respond the rest of this week. -Mark - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: el in JSTL / JSP 2.0
I had the same prob. And 2 things I did that worked:
1. try using the 2.4 schema definition in web.xml
2. if the PermittedTablibs.tld is involved make sure your taglib-uri is
http://java.sun.com/jsp/jstl/core
Good luck

Paid jakarta-taglib consulting
Hello List, I'm an engineer working on a large Java Struts application. We're doing some due diligence on the xtags library as it relates to other taglibs. We'd like to engage a Senior member of the taglib team to help us with our overall jsp architecture as it relates to jakarta-taglibs (html, string, xtags, sslext, etc) we're using. We also have one or two xtag implementation issues. We're looking to expedite our development process, and are resource short at the moment. I would anticipate ~ 1 day of work to start, and have plenty of budget.

fmt:message and Chinese chars
Hi, I've been trying to get a chinese version of a web page going. I switched over to JSTL from struts tags a couple of days so I'm still pretty new with JSTL. My page works fine if I use the struts bean:message tag, but if I change this to fmt:message then it prints out a bunch of garbage charaters. **This only happens with the chinese version of my page**, the english version works fine. I am using JSTL 1.0 since we are on Tomcat 4, so if this is a bug that has been fixed for newer versions then I guess I'll just have to stick with struts tags until we move to TC 5. I prefer the JSTL tags though because nesting the message parameters is much cleaner. Thanks Daryl Handley - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: message and Chinese chars
Darly, I am not sure if this is an issue for your case or not but JSTL independently loads and uses it's own resource bundles NOT the Struts ones. Because our project needs a special MessagesResourcesFactory, we cannot use the JSTL fmt lib.

RE: message and Chinese chars
Doug, I think I'm ok there. I have this line in my web.xml (after getting stuck on this issue yesterday) context-param param-namejavax.servlet.jsp.jstl.fmt.localizationContext/param-name param-valueApplicationResources/param-value description/description /context-param It works for the english version (and parts of the chinese resources that are in english such as my charset and font which I define in the resource bundle. Some may shudder at this, but it works quite well and is super easy). Is there something I'm missing ?

RE: el in JSTL / JSP 2.0
Hi,
Tbanks for that. I was using the 2.4 schema:
web-app 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
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd;
version=2.4
And tried (although PermittedTablibs.tld is not in the picture):
taglib
taglib-urihttp://java.sun.com/jsp/jstl/core/taglib-uri
taglib-location/WEB-INF/tld/c.tld/taglib-location
/taglib
Using this gave me a 500 error (can't find said file). Before edition it
looked something like:
taglib
taglib-urihttp://java.sun.com/jstl/core/taglib-uri
taglib-location/WEB-INF/tld/c.tld/taglib-location
/taglib
The code hasn't changed (below). Are you suggesting I use that URL in
the JSP / .tag? If so, my IDE cannot resolve the library (IDEA).
Thanks for your thoughts.
Paul.

RE: el in JSTL / JSP 2.0
Hi,
It took me a while to get IJ/Jboss3.2.5(tomcat5)/JDK1.5 working but the
above finally rendered jstl 1.1 ${2+2} without using c:out
value=${2+2}/
That is what I am trying to do, embed some el in my JSTL (two
int attributes passed into my tag, and the tag then iterates for the
defined number). It works with static nos, but does not accept the el
(${status.count} is fine):
c:forEach begin=${a} end=${b} varStatus=status
${status.count} br/
/c:forEach
Where static values are fine: c:forEach begin=1 end=5
varStatus=status
I made mods as per your email (source included at the foot). Idea 4.5
now is happy with %@ taglib uri=http://java.sun.com/jsp/jstl/core;
prefix=c % in my JSPs (mysterious), but I am still getting the same
message. Here's the 3 source files again.
Thanks again for your help

IDEA 4.5 will not complain about the 2.4 schema spec of web.xml however
note
jars in web-inf/lib will be default added to library.
Try web.xml:
?xml version=1.0 encoding=ISO-8859-1?
web-app 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
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd;
version=2.4 (as you have)
jsp-config (new 2.4 xml tag)
taglib
taglib-urihttp://java.sun.com/jsp/jstl/core/taglib-uri
taglib-location/WEB-INF/tld/c.tld/taglib-location (make sure
this path is correct)
/taglib
/jsp-config
/web-app
Then in jsp:
%@ taglib uri=http://java.sun.com/jstl/core; prefix=c % (must be
same
as in web.xml, technically can be anything unless permittedTags
involved)
Start simple w/ EL: ${2+2}
With IDEA 4.5 you should get green bars for both the web.xml and the jsp
file (the c.tld is all red, but no matter as tomcat 5 will still work)
when
the taglib-uri paths match.
As part of the jsp 2.0 spec, taglib is optional in jsp's as the
container
knows of them by default.
It took me a while to get IJ/Jboss3.2.5(tomcat5)/JDK1.5 working but the
above finally rendered jstl 1.1 ${2+2} without using c:out
value=${2+2}/
Sound like you are almost there...
