As you state, your service layer cannot choose which implementation to use. That's where you use IoC for. When you build up your web-app, you choose which jars are included in the war file. One of these jars will contain an IoC configuration file (e.g. spring context) which is loaded and creates the repository implementation. All the service layer needs to know is: "at runtime, some form of repository is provided to me". Alternatively, you can use an Abstract Factory to retrieve a repository instance. Personally, I prefer IoC. Hope this answers your question. If you use the “Separated Interface Pattern”, you don’t have a dependency from Domain to Infrastructure, but the other way around.

In our developmentgroup we are currently busy with a refactoring project "Design For Testability" and moving the Repository-interface out of the persistance layer and into the Domain Layer is exactly the way we go as well. Because we need to create stubbed/mocked implementations of the Repository, that do not have any dependency to our ORM-persistance store this is very defendable. What I miss though in the clear pictures is; where do you tigh everything together? That is, if you do not have a dependency from your application-layer to your persistance layer anymore than where do you buildup the implementation of the Repository that is created for persistance? Am I missing the Infrastructure layer which contains a Factory or IoC to loadup the actual repositories/services? Hello Allard, great article.

As far as I know these libraries cannot be found in a maven repository and you have to install them yourself. Please check the comments, someone else has asked this question before.

The pom.xml? I just open it with intellij and everything works nicely together. I have no experience with EclipseIDE or flex builder. What file are you talking about? The pom.xml?
