I'm building a webb app with Jboss 4.0.4 and the lastest build of Seam. I want my web app to be deployable on any jboss AS without seam being previously installed. Therefore I bundle the jars I need during my ant build and put the seam jars in WEB-INF/lib of my .war. I'm using facelets for the views so I have included the following jars: jboss-seam-ui.jar jboss-seam-debug.jar jsf-facelets.jar el-api.jar el-ri.jar" and "jboss-seam.jar" in the root of my .ear along with any other jars i have used for my .ejb3 package. However jboss is having trouble finding a component i have listed in my faces-config.xml which is located in the WEB-INF directory: 15:18:27,073 INFO [FacesConfigurator] Reading config /WEB-INF/faces-config.xml 15:18:27,182 WARN [LocaleUtils] Locale name in faces-config.xml null or empty, setting locale to default locale : en_US 15:18:27,188 ERROR [ClassUtils] Class com.sun.facelets.FaceletViewHandler not found java.lang.ClassNotFoundException: No ClassLoaders found for: com.sun.facelets.FaceletViewHandler (exception stack) I also have the "jboss-seam.jar" and "jboss-seam-ui.jar"in the /default/lib directory of the server. Is the correct place to put the seam jars needed to use EJB3 and facelets? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4035527#...
