The ActionMessage class is in the more recent nightly
builds of Struts. Are you using html:messages? This
uses that class. I'm not what else would be looking
for this in a JSP page though. The validator tags
shouldn't be making a reference to this class.
To check if the ValidatorResources are loading you can
see something print to the console window if the debug
for the ValidatorServlet is set to greater than 1. I
would try to get the server side validation working
before testing the client side. Once the server side
is working, the client side validation shouldn't be a
problem.
