file upload in JSF using myfaces component

Question

I am creating a JSF application where file uploading functionality is required.I have added all the required jar files in my /WEB-INF/lib folder.

jsf-api.jar
jsf-impl.jar
jstl.jar
standard.jar
myfaces-extensions.jar
commons-collections.jar
commons-digester.jar
commons-beanutils.jar
commons-logging.jar
commons-fileupload-1.0.jar

but still when trying to deploy the application on apache 6.0.29 i am getting the following error.

org.apache.catalina.core.StandardContext
addApplicationListener
INFO: The listener "com.sun.faces.config.ConfigureListener" is already
configured for this context. The duplicate definition has been ignored.

I got also problems with myfaces-extensions using x tags. The conflict is due to the fact that myfaces is a very old solution and if your other libraries are uptodate the versions won't match. As posted at tomahawk inputfileupload uploaded file is null in my answer you should use tomahawk t tag and libraries related to it. Actual solution is posted in the main answer of that very same link.

I'm pretty sure this will do the thing. Tick my answer if the post included the answer to your question in its wiki-link :)
