When using JSTL in JSP, getting an exception

Getting following exception when I have included:

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

Exception:

java.lang.NoClassDefFoundError: javax/servlet/jsp/tagext/TagLibraryValidator

What I have done:

  1. Included JSTL jar file WEB-INF/lib folder
  2. Included Classpath in Run Configuration (using Eclipse)
  3. Included in Build path too.

1: Included JSTL jar file WEB-INF/lib folder

Fine. That ought to be sufficient.

2: Included Classpath in Run Configuration (using Eclipse)
3: Included in Build path too.

Don't do. Eclipse does that automatically on 1. You need to undo all manual changes, they might make things worse.

I have included JSTL.jar(Version 1.2) and JSTL Standard.jar

Get rid of standard.jar. JSTL 1.2 consists of only one JAR file. The standard.jar might want to locate classes which doesn't exist in JSTL 1.2 anymore, resulting in this kind of abstract/dependency errors.

You need to include both jstl.jar and standard.jar in your WEB-INF/lib folder.
