java.lang.ClassNotFoundException: com.sun.faces.config.ConfigureListener when using MyFaces with WASCE/Geronimo

Question

I am trying to create a simple JSF web application using MyFaces v 2.1 with WebSphere Application Server Community Edition v3.0.0.1 and Eclipse Juno but when I try to run the application the following error is returned

    java.lang.ClassNotFoundException: com.sun.faces.config.ConfigureListener

Presumably the error is occurring because the MyFaces jar files are not in the class path however I cannot figure out where I’m going wrong as the build path in Eclipse contains the required jars. I’ve also tried copying the jar files into the WEB-INF/lib directory but to no avail.

The screenshot below shows the project structure along with the libraries.

Is there something specific I need to do either in Eclipse or WASCE to include the jar files or does the problem lie elsewhere?

Answer 1

Caused by: java.lang.ClassNotFoundException: com.sun.faces.config.ConfigureListener

The missing class is part of Mojarra, which is actually the competitor of MyFaces.

You shouldn't need that class at all when using MyFaces. This exception can have the following possible causes:

• There's a manually definied <listener> entry in webapp's web.xml or the web-fragment.xml of any of the deployed JARs in /WEB-INF/lib which references this Mojarra-specific listener class.

• There's somewhere a loose Mojarra .tld file in the classpath (very unlikely, who would ever extract a JAR file and put its loose contents in the classpath?). TLD files get autoinitialized and can contain a <listener> entry which can trigger autoregistration of a ServletContextListener implementation (such as the Mojarra ConfigureListener).

Those conflicts can be fixed by just removing it.

Answer 2

I deployed an web application with Myfaces in a Jetty server and it was necessary to use a listener and an additional init parameter to use facelets:

<context-param>
    <param-name>org.apache.myfaces.FACES_INITIALIZER </param-name>
    <param-value>org.apache.myfaces.webapp.FaceletsInitilializer</param-value>
</context-param>
<listener>
     <listener-class>org.apache.myfaces.webapp.StartupServletContextListener</listener-class>
</listener>

Answer 3

I was using mojarra implementation for compilation and was relying on apache tomcat for runtime. But tomcat uses myfaces implementation. So had to include mojarra impl jar in the WEB-INF/lib to resolve the issue

Answer 4

I was with the same problem. When I tried to run a .html file with Eclipse using Tomcat7 as the local server I received the 404 error on the Browser. And in Eclipse's console was showing the error "ClassNotFoundException: com.sun.faces.config.ConfigureListener".

The problem was the Mojarra library (.jar) I was using in my Dynamic Web project. I was using the javax.faces-2.3.0-m04.jar.

-> Solution:

Download an older version on Mojarra's repositories https://maven.java.net/content/repositories/releases/org/glassfish/javax.faces/ . In my case, I downloaded the 2.2.7 version (javax.faces-2.2.7.jar).

Then I created a new Dynamic Web project in Eclipse using JSF v2.0 and assigned with the javax.faces-2.2.7.jar file in the library section.
