I followed your instruction and it works at least for the standard components. I didn't try AJAX components from the Sandbox yet. Should they work as well? Here my recap: 1) Place tomahawk-1.1.3.jar, commons-fileupload-1.1.1.jar, commons-lang-2.1.jar (may be some other dependencies) into $JBOSS_HOME/server/default/deploy/tomcat55.sar/jsflibs 2) Alter /WEB-INF/web.xml according to http://myfaces.apache.org/tomahawk/extensionsFilter.html 3) Declare the taglib in your web.xml file <context-param> | <param-name>facelets.LIBRARIES</param-name> | <param-value>/WEB-INF/tomahawk.taglib.xml</param-value> | </context-param> 4) Create tomahawk.taglib.xml in /WEB/INF folder of your project I've found list of standard tags here: http://wiki.apache.org/myfaces/Use_Facelets_with_Tomahawk Question: should a standard taglib definition be better included in a some way directly in the tomahawk jar file in order to avoid steps 3 and 4? Taglib file sample for Sandbox components can be found here: http://wiki.java.net/bin/view/Projects/FaceletsTaglibsMyfacesSandbox View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3969194#...
