I have a bean called LoginBean that performs extensive validation of the user.
LoginBean has an instance method called validateUser which is called from my Action Class.
Question: Within a method of LoginBean, why is Action.saveMessages(request, messages) not visible? I see from the Docs that saveMessages is protected. But, even if I have LoginBean extend Action, then saveMessages still isn't visible. I don't believe my LoginBean should extend Action anyway, and yet I do believe my LoginBean should be able to add ActionMessages to the request object. Where am I haywire?
My bigger picture is, if the instance of LoginBean, called loginBean, detects a particular error, then it will create and throw a custom Exception, called HrDbNotFoundException. I have a Global Exception Handler defined in the config file to send the exception somewhere where the ActionMessage(s) can be printed.
Thanks.
Matt
