java.lang.ClassNotFoundException: javax.servlet.jsp.jstl.core.Config [duplicate]

Answer 1

The error is telling you it cannot find the class because it is not available in your application.

If you are using Maven, make sure you have the dependency for jstl artifact:

<dependency>
      <groupId>javax.servlet</groupId>
      <artifactId>jstl</artifactId>
      <version>1.2</version>
</dependency>

If you are not using it, just make sure you include the JAR in your classpath. See this answer for download links.

Answer 2

Download the following jars and add it to your WEB-INF/lib directory:

• jsp-api-2.0.jar
• jstl-1.2.jar

Answer 3

Add JSTL library as dependency to your project (javax.servlet.jsp.jstl.core.Config is a part of this package). For example, if you were using Gradle, you could write in a build.gradle:

dependencies {
    compile 'javax.servlet:jstl:1.2'
}

Answer 4

I had the same problem. Go to Project Properties -> Deployment Assemplbly and add jstl jar

Answer 5

By default, Tomcat container doesn’t contain any jstl library. To fix it, declares jstl.jar in your Maven pom.xml file if you are working in Maven project or add it to your application's classpath

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>jstl</artifactId>
    <version>1.2</version>
  </dependency>

Answer 6

Probably the jstl libraries are missing from your classpath/not accessible by tomcat.

You need to add at least the following jar files in your WEB-INF/lib directory:

• jsf-impl.jar
• jsf-api.jar
• jstl.jar
