I fully agree with those architecture consideration. What I see in struts2 is that I can use my business service as MVC controler with no dependency on the web framework. My business service only has to switch from a stateless-style (method with parameters) to a statefull or command-style (properties for input / output + execution method).
If I write my business layer this way, I don't consider it to become part of the wab layer, but it can be used directly by strut2 as an "Action" by simply setting the expected properties in the valueStack and executing the business method. Am I wrong ? 2007/4/18, Ray Clough <[EMAIL PROTECTED]>:
Architecture is architecture, regardless of whether it is Struts-1, Struts-2, or something else. A Service Layer has the benefits of giving clear separation of function between the Controller (Struts) and the Application. The web framework (here Struts) is primarily a vehicle for delivering data back and forth between the Application and the user. The application should be independent of the framework. The Service Layer is really the API for your application. Without using a Service Layer, you tend to get lots of Business Logic in the Action classes, which will tie your application not only to the framework, but to the type of delivery platform (eg a Web App), which will prevent you from later making a Swing app or something else out of it if you want to. - Ray Clough nicolas de loof-2 wrote: > > Hello, > > I've used struts1 for several years and I'm now looking at Struts². > > In struts1, to create a "registerUser" use-case I need a RegisterAction, a > RegistrationService and some business code. > My struts1 RegistrationService is only used to start a transaction using > Spring @Transactional annotation.
