When I run the following jsp, I am getting the error in the attached txt file.


<%@ taglib uri="http://java.sun.com/jstl/core" prefix="c" %>

<html>  <
      head>    
            <title>Count to 10 Example (using JSTL)</title>  
      </head>  

      <body>    
            <c:forEach var="i" begin="1" end="10" step="1">      
            <c:out value="${i}" />      
            <br />    
            </c:forEach>  
      </body>

</html>

Do I need to have jstl-1.2.jar in:

Tomcat 5.0\webapps\ROOT\WEB-INF\lib\

or

Tomcat 5.0\common\lib

I have jdk version j2sdk1.4.2_01.

Thank you

I just realized that Tomcat 5 is too old for JSTL 1.2.
I think you need to go to  
http://archive.apache.org/dist/jakarta/taglibs/standard/binaries/ 
and download  
jakarta-taglibs-standard-1.1.2.zip  
Unzip it and look in the folder
jakarta-taglibs-standard-1.1.2/lib  
and you will find two jars;  
jstl.jar and  standard.jar  
Put those two jars into  
Tomcat 5.0\common\lib

In my own laptop I have 7.0 but at work, I have to use version 5.

any idea what the error is complaining about? I did put jstl-1.2.jar in common\lib folder.

Does it get uncompressed automatically? Does the error has something to do with the this version of jstl (jstl-1.2.jar in)?

Why the above jsp not working? It is supposed to list 1 to 10 (in 10 lines)?

Thanks

I forgot to tell you that  
><%@ taglib uri="http://java.sun.com/jstl/core" prefix="c" %>  
Was for JSTL 1.0  
For JSTL 1.1 and greater,  we have to use  
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>

>any idea what the error is complaining about?  
>java.lang.UnsupportedClassVersionError: org/apache/taglibs/standard/tlv/JstlCoreTLV (Unsupported major.minor version 49.0)
This error is given because the new features introduced in the newer version of Java are not present in the older version.

No. java just reads it.

In common\lib folder, I have 73 files. This means I possibly have all I need and it is not required to download something else.

How can I what version of JSTL I have so that we can modify the directive (<%@ taglib uri="http://java.sun.com/jstl/core" prefix="c" %>) accordingly?

Please see the attached screen-sholt of the files in this folder.

What did you download ?  
Anyway, just use  
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>    

>How can I what version of JSTL I have  
You could make a copy of it and change the file name to xxx.zip. Unzip it and look in  the META-INF/MANIFEST.MF file.

re:> What did you download ?

I have not dowloaded yet because I had 73 files in common\lib folder thinking I have already what I need. So the question is how to modify the directive (in the book example:<%@ taglib uri="http://java.sun.com/jstl/core" prefix="c" %>) to work with what I already have.

I did try:

<%-- <%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %> --%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>

but got the attached error (maybe the same as before).

I am sorry.  I didn't think there was going to be a  problem.
Now I notice in  your common-lib-folder.bmp that you have both versions in there.  
Please remove
jstl-1.2.jar  
You can't use that in Tomcat 5 and it might be causing the problem.  
You have the jstl.jar and standard.jar already in there. Good.  You can check the version in the manifest(in jstl.jar) as I posted above here. If its 1.1x then use
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
