Error while deploying Primefaces-Extensions example, why?

Deployment error: application loading exception: java.lang.IllegalStateException: ContainerBase.addChild: start: org.apache.catalina.LifecycleException: java.lang.RuntimeException: com.sun.faces.config.ConfigurationException: java.lang.ClassNotFoundException : org.apache.commons.lang3.StringEscapeUtils The module has not been deployed.

This is my code:

As said at the beginning of the work on the perffaces extensions project at https://github.com/primefaces-extensions/primefaces-extensions.github.com/wiki/Getting-Started , you need to add "Apache Commons Lang3" to your project.

Add Apache Commons Lang3 to your project if it is not in the classpath.

You can download the library from http://commons.apache.org/proper/commons-lang/
