java.lang.ClassNotFoundException: javax.faces.application.ApplicationFactory

Question

I am writing a web application using JSF 2. I have downloaded mojarra-2.1.3-FCS-binary.zip and myfaces-core-assembly-2.1.3-bin.zip, and with each library, I'm getting the following exception:

For Mojarra, I included javax.faces.jar in WEB-INF/lib folder, and for MyFaces, I replace the jar with the following: myfaces-api-2.1.3.jar, myfaces-bundle-2.1.3.jar, myfaces-impl-2.1.3.jar.

I've included jstl-api-1.2.jar as well as jstl-impl-1.2.jar.

And ApplicationFactory is found in those jars. What is the issue with JSF in these instances?

I'm using Tomcat 7 to run my web application.

Have you tried to locate the Libaries under "/apache-tomcat-7/lib" ? — Mhh Lecker

@Mhh Lecker, the jars mentioned in the question contains the classes. It doesn't "register" when you run the application though. — Buhake Sindi

This exception suggests that the Mojarra API was been loaded from the server-dedicated classloader while the Mojarra/MyFaces impl is loaded from the webapp-dedicated classloader. Remove the Mojarra JARs from Tomcat/lib, JRE/lib, JRE/lib/ext and/or Tomcat common lib and eventually all places in webapp's runtime classpath other than /WEB-INF/lib.

I double checked and the javax.faces.jar is only found in my WEB-INF folder. I'm running Tomcat 7.0.20.

jsf-api.jar? javaee.jar? Come to think about it, do you have any JSF specific/related <listener> in web.xml? What Servlet version is your web.xml root declaration set to?

Does jboss-seam.jar have anything to do with the conflict?

Buhake Sindi Over a year ago

jsf-api.jar, javaee.jar is not found in any "system" lib folders and Serlvet version is 3.0. and I don't have any listener specified yet.

Found it. It seems that jboss-seam.jar creates a conflict with my application. Thanks BalusC.
