You should see log messages when you access your first facelets page 13:20:37,850 ERROR [STDERR] 04-Dec-2006 13:20:37 com.sun.facelets.compiler.TagLibraryConfig loadImplicit | INFO: Added Library from: jar:file:/Z:/jboss/jboss-4.0.5.GA/server/default/./deploy/spm-seam.ear/spm-seam.war/WEB-INF/lib/jsf-facelets.jar!/META-INF/jsf-core.taglib.xml for all the tag libraries facelets can load (for the entire app). If your nt.taglibrary.xml isn't mentioned please post your war structure. If it is then you've probably got a namespace typo between nt.taglib.xml and your facelet.
