Sorry if it seems like I'm attacking anyone, I'm not... Currently I'm trying to start a ERP style project. Initially generating most of the scaffolding from Spring Roo (once 1.1.1 is released). This will give me my entities, and scaffolding for my activities and places.
I'll be using MySQL as my DB And thanks to you and others on this group there's already lots of documentation available to me,(Activity / Places) so I can understand and manipulate the scaffolding to suit my needs. But what I cannot figure out is how I'm going to implement the Service Layer GWT 2.1.1 stuff to put some business logic into my App so that I can add some business functionality to the App. So ideally I'd like some documentation that could explain how I can implement business logic in my service layer while keep my entities very POJO like. Even something as simple as a bank account app. Adding and deleting money form a checking and saving a/c's etc. What's frustrating is since I've being following GWT 2.0, so much has changed and I always feel like I'm waiting on the next release of GWT to start implementing the project, reason being 2.1 gave me Activities and Places and are more suited to CRUD (data-oriented) apps with an ORM (I'll be using Hibernate) like interface on the client. But then I've had to wait till 2.1.1 for the service layer (business logic). I'm not an senior software engineer, just an software engineer who loves Java and GWT (I have very strong Java fundamentals), but finding it hard to wrap my head around everything without documentation and a sample app Just looking for some help from the community on how this all works with a small sample app. Am I wrong with what I'm thinking the new Service Layer in 2.1.1 is supposed to provide. thanks and looking forward to any doc's that are in the works On Jan 10, 1:08 pm, David Chandler <[email protected]> wrote: > Hmm, what exactly are you calling the new Service layer?
