Eclipse “cannot find the tag library descriptor” for custom tags (not JSTL!)

Question

I have a Java EE project which build fine with Ant, deploys perfectly to JBoss, and runs without any trouble. This project includes a few custom tag librari

Answer 1

I fixed this problem today.

• Change your output directory to your WEB-INF/classes folder. (Project/Properties/Java Build Path, Default output folder)
• Assigne the module dependencies. (Project/Properties/Java EE Module Dependencies) they will be copied to the WEB-INF/lib folder where Eclipse looks for the tag lib definitions too.

I hope it helps.

Answer 2

replace jstl.jar to jstl1.2.jar resolved the issue for tomcat 7.0

Answer 3

Ran into the same problem, I'm using maven so I added this to the pom in my web project:

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>jstl</artifactId>
    <version>1.2</version> <!-- just used the latest version, make sure you use the one you need -->
    <scope>provided</scope>
</dependency>

This fixed the problem and I used "provided" scope because like the OP, everything was already working in JBoss.

Here's where I found the solution: http://alfredjava.wordpress.com/2008/12/22/jstl-connot-resolved/

Answer 4

I had the same problem with MyEclipse and Eclipse 6.6.0. It red lined the uri value in every

<%@ taglib prefix="s" uri="/struts-tags"%>. I fixed it by going to 'Project/MyEclipse/Web/Tag Libraries' and setting the Default TLD Prefix for Struts 1.2 Tiles Tags to 's'. I also had to do the same under 'Project/MyEclipse/Web/Configure workspace settings.../Tag Libraries'.
