i'm having a problem getting a simple struts validator example to
output any errors
using netbeans 3.6, the forms appear and submit ok, but no html:errors
output at all, or console output errors relating to validator.
any suggestions to debug?
i've included files below, TestForm.jsp is the form.
thanks
