The benefit of action chaining, as far as I am concerned, is to promote action reuse. With chaining you can make more fine-grained actions and then chain together those fine-grained actions to create more complex behavior. As an example, let's say you need to validate that a user is logged in prior to executing something. You could create a ValidateUser action and then reuse it throughout your application. In addition, if you make a change in a fine-grained action then your change is reflected anywhere that action is used in a chain.
This is just one example, and there may be ways to do things like this already in WebWork which I am unfamiliar with. In addition, there are others who believe that action chaining is not necessarily a good thing, but personally I find it to be very useful (which is why JPublish includes "action chaining"). Finally, with the Servlet 2.3 API you can have similar functionality using filters. Since WebWork is supposed to be more then a web framework though, it may be beneficial to avoid using servlet-specific features such as this in a WebWork application.
