Generating "user not found" logon error messages

I've got the rudiments of a login going, and I've got the simple error messages working ("Username is required" -- via DynaActionForm and the validation plugin). Now, within my action class, I need to generate errors that are determined by DB interaction, like:

"User not found"
"Invalid password"
"Databaes unavailable. Try again later."

I'm not sure how to feed those errors back into the validation framework. Could someone explain, please?

You don't display those errors through Validation.xml ,as they are not Validation errors.
YOu have to either use ActionMessages or ActionErrors and add those messages into that object and display it on the browser.

Yes, this is beyond the validation framework.

The error does not happen until the Action, so you'll have to handle it in the action. Just add the error to ActionErrors there and don't forget to call the saveErrors() method.

saveErrors(HttpServletRequest, ActionErrors) is deprecated in Struts1.2.
I agree. Here's the link:
