webwork.action.factory.ActionFactory

public class AliasingActionFactoryProxy
extends ActionFactoryProxy

Aliasing action factory proxy. This will convert the given name to a classname of an Action implementation. By using aliases you can give meaningful and easy-to-remember names to your action classes. Using aliases also allow you to use the same action class with many result view mappings.

If the configuration flag "webwork.only.aliasing" is set to "true", then the given name *must* be an alias. Otherwise a security exception will be thrown. This is to ensure that only actions that you explicitly want exposed for invocation can be accessed.

However, actions can always access any other action through the ActionFactory regardless of this setting.
