The implementation for a State Oriented Business Protocol is not that hard to be done and basically I did one using a POJO approach. Using some of the libraries from commons like Digester I parse my static business rules from an xml file. Then, using scxml notation I created all the logic in terms of dynamic configurations and execution of specific actions. Since the project was intended to offer clients the possibility of sending GET/POST HTTP calls and receive XML as the response I just needed to create a Bridge to communicate actions comming to my servlet container to the SCXML Engine. It was easy using reflection to discover which event I had to trigger. Before passing to the SCXML Engine some preconditions can be chequed in that Bridge. After the control is given to the SCXML some post conditions can be evaluated by means of action states. Finally from those action states the SCXML Engine puts the framework in a given State from which only some events will be allowed. - 2)Developing YAWF (Yet Another WEB Framework) + ==== Developing YAWF (Yet Another WEB Framework) ==== - After I developed the above system I came up with an idea that is already explained in my blog[1], but basically I am planning to have my clients use just the VIEW part of the MVC framework I already built using SCXML as Controller. + After I developed the above system I came up with an idea that is already explained in my blog [2], but basically I am planning to have my clients use just the VIEW part of the MVC framework I already built using SCXML as Controller. This is not just a new Framework for Web development. This is a language independent framework where the separation of concerns is of course the main reason to go for it. However why I just do not think about using Sprint or moving into Ruby On Rails for my next project? First I need State Orientation. Second why I have to study a Framework if with simple POJOs that are around or you can build by yourself you end up having the needed behaviour with the needed features. @@ -30, +30 @@ [2] http://softwarethougts.blogspot.com/ + ---- + + ''Posted by: Nestor Urquiza'' + --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
