Why don't use delegate PetStore?

[Jose Jim�nez]

Petstore application use a ClientSessionController how proxy with methods:
handleEvent , getCustomerEJB , .... ) is said that :

1) execute action
2) Have methods that return references to facades

Then .... don't it's necessary use bussines delegate for each facade ?? the client use directly the refences to facades ???

What do you thinks about this ??

Thanks

To me Petstore is not the best solution to a problem but it only demonstrates J2EE capabilities (architectural possibilities?) with whatever design patterns at hand. Not necessary that the used pattern is required. It talks all about session facade and then exposes the customer entity bean through shoppincart statefull session bean. Their excuse is they all use local interfaces. While for a small application this is an overkill to use so many session facades and statefull session beans, for a large application this strong coupling between servlet container and the ejb container won't be a nice thing. But when you seperate them, then you deal with remote interfaces or end up redesining your application.
