Hi, If you use EAR project: - update old /EarContent/richfaces-api.jar to new one - update old richfaces-impl.jar, richfaces-ui.jar in /WebContent/WEB-INF/lib to new ones Please don't rename these jar names otherwise you have to update /META-INF/MANIFEST.MF in ejb and war projects too. If you use WAR project: - update old /WebContent/richfaces-*.jar to new ones Just copy new RichaFaces jars (richfaces-api-*.jar, richfaces-impl-*.jar, richfaces-ui-*.jar) to your web project (/WebContent/WEB-INF/lib) in case of war project. If you use EAR then copy richfaces-api-*.jar to /EarContent View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4225867#...
