I am trying to test my struts actions but can't even get through the setUp method.

All I have in setUp() is:
super.setUp();
setConfigFile("C:/Projects/Enhanced IDE/web/WEB-INF/struts-config.xml");
setServletConfigFile("C:/Projects/Enhanced IDE/web/WEB-INF/web.xml");

The error I get is:
junit.framework.AssertionFailedError: Received an exception while loading web.xml - class java.lang.NullPointerException : null

My web.xml runs fine in my Tomcat container, could it be the relative paths in the web.xml not resolving to proper places (seeing as how ant moves it when it's built). I don't know.  I'm stuck and I'm tired. :(
