The absolute uri: http://java.sun.com/jsp/jstl/core cannot be resolved

Error:
Hit this error while deploying webapps in Tomcat. “The absolute uri: http://java.sun.com/jsp/jstl/core cannot be resolved …”

Story:
I’m trying to include JSTL in JSP pages. I get the above error while starting up the webapp in Tomcat.

Solution:
The jstl.jar is missing from the web deployment package (.war) file. Add in jstl.jar in /WEB-INF/lib/ is the most directive way to solve this problem. If maven is used in the project, we can include the xml code below and let maven do the JAR file searching and packing for us.

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

Thanks for godbiest’s update 🙂
