I have a web application in struts2 framework in NetBeans 7.0.1. it was working fine. But suddenly the Tomcat has started to give the following error:

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

Had the same problem. You probably used NetBeans to auto add this dependency with default 'compile' scope and it broke tomcat:

   <dependency>
        <groupId>javax</groupId>
        <artifactId>javaee-api</artifactId>
        <version>6.0</version>
    </dependency>

Use provided scope like here https://stackoverflow.com/a/10156854/1051834 If it does not help install a fresh tomcat and redeploy your project once again.

  • Thanks, but why does this happen? – Koray Tugay Oct 19 '13 at 21:41

    @KorayTugay: javaee-api jar needs jsf jars so if you add javaee-api jar in your project, you have to add jsf jar also. Thus, either adding jsf jars or removing javaee-api jar at run time (giving provided scope) will solve this problem. "Provided" scope in maven means you need the JAR for compiling, but at run time there is already a JAR provided by the environment so you don't need it packaged with your app so it won't be copied in lib folder. – Mital Pritmani Feb 03 '14 at 06:25

<dependency>
<groupId>com.sun.faces</groupId>
<artifactId>jsf-impl</artifactId>
<version>2.1.6</version>

is worked for me, you can change version as it release new versions.

The jsf-implementation library is missing in your application (it should be in WEB-INF\lib\ directory of application). If you are starting application from Netbeans, this library (jsf-impl.jar?) is configured in classpath of Netbeans project, so there was no error.
