Hi Andrew, You war file work fine in my environment. But I could not figure out why I can not get your tag library to work. I got this error javax.servlet.ServletException: The absolute uri: http://jsf-comp.sourceforge.net/aa cannot be resolved in either web.xml or the jar files deployed with this application javax.faces.webapp.FacesServlet.service(FacesServlet.java:152)
when declaring the tag library as following <%@ taglib uri="http://jsf-comp.sourceforge.net/aa"; prefix="jcaa" %> I have not used many tag libraries using the taglib.xml descriptor. But Tomahawk tags works fine. AA tags works fine too. Playing with your demo makes me really want to get it to work. Do you know how I should register your tag library? I guess I can write a tld for it. But it seems silly.

The WAR that is provided from jsf-comp is my only example that I have that is not commercial. It uses facelets. I haven't tested it with JSP at all (only facelets) as I don't have a JSP setup at the moment. You must make sure the HtmlAaTree component is registered in a faces-config.xml as with the JSP tag class (AaTreeTag). Check your logs to see if the tag and/or component was not found.
