SEVERE: ServletException in '/form/menu.jsp': org/apache/velocity/context/Context

Thanks for any and all help.  I am looking for help in solving this error.  I am trying to get a sample of the Velocity tabbed menus to display.  This exception happens when I try to do a simple Velocity tabbedmenu style.  When I replace the displayer name="Velocity" to name="TabbedMenu" I don't get the exception, however, all of the text of the menu prints like nullnullnullnullnull and there is no rect or image.  I am trying to follow the sample "Integrating Struts Menu into your application" on page http://struts-menu.sourceforge.net/userguide.html
 
My env is:
Eclipse 3.1
MyEclipse 4
StrutsMenu 2.3
Tiles v?
Tomcat 5.0.30
 
Both globalMacros.vm and tabs.html are in my WEB-INF/classes directory.  I have tried the 2 velocity jars both in the project classpath and in the tomcat commons/lib (but not in both at the same time).
 
This is the info:
menu.jsp
<%@ page language="java" pageEncoding="UTF-8"%>
<%@ taglib uri="http://struts-menu.sf.net/tag" prefix="menu" %>
<%@ taglib uri="http://struts.apache.org/tags-html" prefix="html" %>
this footer link shows up in the TabbedMenu version, but not the Velocity version
<html:link forward="footer" >Footer</html:link> 
<menu:useMenuDisplayer name="Velocity" config="tabs.html" bundle="org.apache.struts.action.MESSAGE" >
<menu:displayMenu name="TabbedHome"/>
<menu:displayMenu name="TabbedAbout"/>
</menu:useMenuDisplayer> 
 
menu-config.xml
<Displayer name="TabbedMenu" type="net.sf.navigator.displayer.TabbedMenuDisplayer"/>
<Displayer name="Velocity" type="net.sf.navigator.displayer.VelocityMenuDisplayer"/>
