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"/>
---------
<Menu name="TabbedHome" title="Home" location="?Home" target="_blank"/>
<Menu name="TabbedAbout" title="About">
<Item name="People" title="People" location="?People"/>
<Item name="Careers" title="Careers" location="?Careers" target="_blank"/>
<Item name="Press" title="Press" location="?Press" onclick="alert('This item has an onclick handler in menu-config.xml.')"/>
<Item name="Locations" title="Locations" location="?Locations"/>
</Menu>
