Struts does *exactly* the same thing when it parses your
struts-config.xmlfiles, so it would be helpful for you to see how
that's done (using Commons
Digester).  Check out the initConfigDigester() method of
org.apache.struts.action.ActionServlet, and notice how it uses the
register() method of the Digester instance to register local copies of the
Struts DTDs.

Internally, what's going on is a string like
"/org/apache/struts/resources/struts_config_1_2.dtd" (which points at a
resource file included in struts.jar) is being turned into a URL by calling
ServletContext.getResource() -- exactly what you need to gain access to
anything stored under WEB-INF/classes or WEB-INF/lib.

Please help....
