Hi all,
I'm really excited to start a new project using Virgo. The main reason is that I'd like to really design the new application and separate parts of the application in bundles.
I have 2 questions regarding the design for which I could not find good answer yet.
1) It's relative easy to separate the model, view and controllers in separate bundles. But is it possible to separate parts of the model itself in bundles too?
I envision a core model (say, a user) and lots of possible additions (say, a customer bundle, an article bundle and a order/orderdetail bundle).
How do we then cope with persistence issues? Even if a single ORM is being used for all model persistence, it will be really hard to split the model, isn't it?
I certainly like the idea of being able to add new and remove old bundles on the fly, but I think most ORM's cannot apply model changes during runtime.
Any high-level overview of this with some important details explained is very much appreciated :)
2) I'm also a little confused where to get the documentation for the spring library. Virgo is the same as/based on Spring Dm 2.x as donated by SpringSource, isn't it?
But I can't find the docs at http://www.springsource.org/osgi for 2.x (it's grayed out).
The spring-osgi lib provides simple configuration to define and consume services, right? Then, inside a bundle you could use Spring 3.0 to setup the internal structure of the bundle?
Best regards, and keep up the good work! Thumbs up!
Ronald
