Apache Tomcat Severe Error

SEVERE: Error configuring application listener of class com.sun.faces.config.ConfigureListener
java.lang.ClassNotFoundException: com.sun.faces.config.ConfigureListener

 

Some things to note:

  1. Notice the time stamp beside the exception, this may not be an existing problem. If it happened today, it will always be shown on server startup as tomcat only creates a new log when the date changes (ie new log every day).
  2. Also, when running netbeans, although you may have cleared the logs directory in Apache Tomcat, you will also need to clean them in the catalina base directory. Right click on Tomcat in netbeans and you will see where the catalina base is located. This will then allow you to navigate to the logs to delete them.

For me, this problem was solved by adding

jsf-api.jar
jsf-impl.jar

 

to the lib directory under WEB-INF directory of my project.
