public final class WelcomeAction
extends BaseAction

Confirm required resources are available before displaying initial page.

If a resource is missing, forward to "failure". Otherwise, forward to "success", where success is usually the "welcome" page.

Since "required resources" includes the application MessageResources the failure page must not use the standard error or message tags. Instead, it display the Strings stored in an ArrayList stored under the request attribute "ERROR".
