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.
