Well, if I leave the facelets classes where they are, I get a ClassNotFoundException when I try to render a page (deployment works ok). However, declaring the facelets JAR as java module as well, gives me the following exception: | org.apache.myfaces.trinidadinternal.facelets.TrinidadComponentHandler must be an instance of com.sun.facelets.tag.TagHandler | com.sun.facelets.compiler.TagLibraryConfig$LibraryHandler.createClass(TagLibraryConfig.java:281) | com.sun.facelets.compiler.TagLibraryConfig$LibraryHandler.endElement(TagLibraryConfig.java:206) | However, TrinidadComponentHandler does extend TagHandler, so there must be another classpath problem somewhere. I don't think I understand quite well how that works... View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4005944#...
