Thanks a /ton/: that was the whole problem.

Yep, my web.xml says:

http://java.sun.com/xml/ns/javaee";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd";

It just looks like I had the wrong tablib URI. Inspecting the tag
library JAR files, I can see that these two URIs are valid:

JSTL 1.0: http://java.sun.com/jstl/core
JSTL 1.2: http://java.sun.com/jsp/jstl/core

Apparently, the 1.0 version doesn't allow EL expressions (and presumably
must operate directly on a named page/request attribute).

Switching to the 1.2 tag library URI did the trick.

Thanks a lot!

The correct core taglib uri for JSTL 1.2 is: http://java.sun.com/jsp/jstl/core

Also make sure you're using a Servlet 2.5 web.xml.

Find the TLD that it's referencing and look at the 'items' attribute.
If it says rtexprvalue="false" it's wrong.  If it says 'true' then we're
looking in the wrong place.

Placing my entire WAR file into the environment where I could get the
JSP working results in the same error (full stack trace this time, just
in case it's relevant):

org.apache.jasper.JasperException: /tasks.jsp(18,6) According to TLD or

Basically, my servlet creates a List of Task objects and puts them into
a request attribute called "tasks", then does:

getServletContext().getRequestDispatcher("/tasks.jsp")
.forward(request, response);

This is pretty simple stuff: what am I missing?

TC 6 & JSTL: attribute does not accept any expressions

2010-05-07 Thread Christopher Schultz 

All,

I'm a complete newbie to JSTL and I'm having trouble getting a simple 
page to render. The page below gives me the error:


org.apache.jasper.JasperException: /tasks.jsp(18,6) According to TLD or 
attribute directive in tag file, attribute items does not accept any 
expressions

org.apache.jasper.compiler.DefaultErrorHandler.jspError(DefaultErrorHandler.java:40)
org.apache.jasper.compiler.ErrorDispatcher.dispatch(ErrorDispatcher.java:407)
[...]

It seems to me that "items" had better be an expression.

I have a fresh install of Tomcat 6.0.26 running on Sun's 1.6.0-_20-b02 
JVM on 32-bit Linux. I downloaded the JSTL "api" and "impl" packages 
from https://jstl.dev.java.net/download.html and put the JAR files 
directly into WEB-INF/lib.


<%@ page
  pageEncoding="UTF-8"
  import="lj.timesheet.Task"
%>
<%@ taglib prefix="c" uri="http://java.sun.com/jstl/core"; %>

  
My Tasks
  

  
My Tasks


  
Description
  
  

  

  

  


I had this problem on my Linux desktop which I then rebooted back into 
Windows to write this message. Just for kicks, I tossed this JSP onto my 
dev server for work (and removed the reference to the Task class) and it 
worked no problem.


The differences I can see between these environments are:
1. No "Task" import in the environment where it works
2. Direct call to the JSP in the environment where it works
   (rather than calling a servlet which forwards to it)
3. Slightly different Java version (it's 1.6.0-12 in the
   working environment)
4. Working environment is using CATALINA_BASE to run Tomcat from
   a separate directory than the actual distro


Can anyone shed any light on this? I'm going to toss my entire WAR file 
into the environment where it /is/ working to see if it's some 
interaction problem.


Thanks,
-chris
