Unable to Resolve JSTL taglib Declaration

[Somnath Mallick]

Hi Everyone,

I am trying to use JSTL taglibs in my JSP page. I have added the line:

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

at the start of the JSP. I also have standard-1.0.6.jar and jstl-1.0.4.jar downloaded from maven in my classpath. But in Eclipse I get an error saying that:

Cannot find tag library descriptor for http://java.sun.com/jsp/jstl/core

[Bosun Bello]

Verify that those jars are in ' WEB-INF/lib' of your application.

[Somnath Mallick]

Yup they are in WEB-INF/lib folder of my eclipse project. Also would like to know that should we make changes in the web.xml file for adding taglibs?

[David Newton]

Isn't that a really old version? (Can't keep the versions straight in my head.)

If it is, try:

<uri>http://java.sun.com/jstl/core</uri>

as the URI--it changed.

[Somnath Mallick]

http://java.sun.com/jstl/core worked! Man... these versions!

[Somnath Mallick]

Well now i run the jsp page and i get an error:

[David Newton]

Where do you configure soemthing to use /WEB-INF/c.tld?

[Somnath Mallick]

Well i didn't get your question! Well eclipse does that automatically edits the web.xml file, doesn't it?

[David Newton]

Something in your project refers to /WEB-INF/c.tld. If there's no TLD file there that won't work.

[Bear Bibeault]

Why are you using an antiquated version of the JSTL to being with?

[Somnath Mallick]

Well my web application is in version 2.4. I am using Tomcat 6.0.20. Actually I have to use the code for Java 1.4. So i have to use JSTL 1.1 specification. I read that JSTL 1.2 can be used for web application version 2.5 and and Java 1.5.

[Sri Karr]

Have you looked at your web.xml file in your application.
I hope the below information will resolve your problem.
