Have you specified the messages "shadow.error.username" and "shadow.error.password" in Application.resource file. If not then even though validation method is being called, you won't see the error.
Is there a reason I would check for a null value on the fields using struts?
The only access to my ActionForm is from my login form so presumably there could never be a case where where the values are null. Or have I missed something in my newbie struts endeavours?
