Marked as OT because this more of a conceptual issue and has to do with talking to .NET developers regarding framework difference than with framework use.
I'm trying to wrap my head around the Model View Pattern (MVP) pattern. My issue is that I can't really differentiate it from what I do in Struts2. But in no documentation is there any claim that Struts2 follows MVP. Also it seems to be a term that only shows up mainly in Microsoft circles, is it a sort of branding? Given the Wikipedia article: http://en.wikipedia.org/wiki/Model%E2%80%93view%E2%80%93presenter There is a picture at the top of the wiki article that shows the following: ---- Model Business Objects <=> Presenter Contains the logic for application <=> View UI Components Has no notion of the model. ---- This looks a lot like, the pattern most of us take for Struts2, where the middle part, the presenter, is replaced by the Struts2 action. The main difference is that this is less of an abstraction than found in most JEE applications, as the chain is typically: Data tier objects <=> service tier objects <=> struts2 action <=> view. I'm supposing that this extra level, isn't required for the MVP pattern and so omitted to focus on the pattern and not perhaps would be done in best practice. So is then is Struts2 following MVP (in most cases)? I've read that wiki article twice and still don't see a difference. Any light on the matter would be most welcome. On the other hand if there isn't a difference, we should add Struts2 to the list of MVP frameworks at the bottom! Regards, Ken
