JSTL error javax/servlet/jsp/jstl/core/LoopTag error when using c:forEach tomcat ver7.0

Question

Hi using
eclipse juno, dynamic web project
apache Tomcat v7.0 (which has its own jstl-1.2.1.jar) I get this error

javax.servlet.ServletExc         


        

Answer 1

javax.servlet.jsp.jstl-1.2.1.jar doesn't contain the javax.servlet.jsp.jstl.core classes. Be sure to add jstl-1.2.jar as well.

Answer 2

If you are using maven, add

<dependency>
  <groupId>javax.servlet</groupId>
  <artifactId>jstl</artifactId>
  <version>1.1.2</version>
</dependency>

to your pom.xml

Answer 3

If you want to use forEach you should add two libraries to WEB-INF/lib of your project: Impl: taglibs-standard-impl-1.2.5.jar Spec: taglibs-standard-spec-1.2.5.jar

Answer 4

I had a similar problem, using conditional tag <c:if>. I was only using taglibs-standard-impl-1.2.5.jar.

After downloading the jstl.jar from jstl.jar download page and adding it to Tomcat's installation lib directory it works.

Answer 5

I imported "taglibs-standard-impl-1.2.5.jar" I downloaded from http://tomcat.apache.org/download-taglibs.cgi and I encountered the same error. I tried importing "jstl-1.2.jar" as Limited Atonement suggested before and it worked. So I compared those two jars:

• "jstl-1.2.jar" contains 3 folders: "javax", "META-INF" and "org".
• "taglibs-standard-impl-1.2.5.jar" contains only 2 folders: "META-INF" and "org".

So I tried swch's suggestion. I removed jstl-1.2.jar and importing both "taglibs-standard-spec-1.2.5.jar" and "taglibs-standard-impl-1.2.5.jar".

This solved the issue, because the "spec" lib contains the "javax" folder which contains the required classes.
