I am currently seeing a similar exception: SEVERE: Exception sending context initialized event to listener instance of class com.sun.faces.config.ConfigureListener com.sun.faces.config.ConfigurationException: CONFIGURATION FAILED! org.ajax4jsf.renderkit.ChameleonRenderKitFactory ....... Caused by: java.lang.InstantiationException: org.ajax4jsf.renderkit.ChameleonRenderKitFactory I don't have a solution yet, but I believe it's a library issue. You may want to check for updated libraries and see if that helps. View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4239513#...
