Hi I have downloaded jbossportal 2.4CR3 ( JBoss AS 4.0.4.GA) from the site and replaced all the myfaces jar file for version 1.1.3. Am trying to deploy the portlet which works in jbossportal version 2.2.1 SP1, it throws the following exception. 09:57:35,663 INFO [HtmlRenderKitImpl] Overwriting renderer with family = javax faces.Command rendererType = javax.faces.Button renderer class = org.apache.myf ces.renderkit.html.jsf.ExtendedHtmlButtonRenderer 09:57:35,820 INFO [HtmlRenderKitImpl] Overwriting renderer with family
