java.lang.ClassNotFoundException : javax.servlet.jsp.jstl.core.Config

Problem

While deploying JSF 2.0 web application to Tomcat 6.0.26, hits following jstl class not found error.


java.lang.NoClassDefFoundError: javax/servlet/jsp/jstl/core/Config
	...
Caused by: java.lang.ClassNotFoundException: javax.servlet.jsp.jstl.core.Config
	... 18 more

Solution

By default, Tomcat container doesn’t contain any jstl library. To fix it, declares jstl.jar in your Maven pom.xml file.


  <dependency>
	<groupId>javax.servlet</groupId>
	<artifactId>jstl</artifactId>
	<version>1.2</version>
  </dependency>
Note
Please refer to this JSF 2.0 release note to identify the JSF 2.0 required dependency libraries.

  4. Hi,

    Thank you for the solution but i don’t use Maven, i copied the library into /WEB-INF/lib/ but it gives the following error:

    javax.servlet.ServletException: java.lang.NoClassDefFoundError: javax/servlet/jsp/jstl/core/ConditionalTagSupport
    org.apache.jasper.servlet.JspServlet.service(JspServlet.java:339)

  7. Thank you for this little tip. This is the first time I found a tip at the top of google search on ‘..some err..classNotfound,jstl…’ where I followed the simple dependency injection, and it worked like a magic charm!

    javax.servlet
    jstl
    1.2

    1. Thank for the input. Tomcat, by default, doesn’t come with jstl.jar library, and shouldn’t also. You need to get this library manually.
