This apparent duplication of code in the DTO classes, sure to be a negative aspect of the solution, which can be seen as similar as the stubs classes we see in JAX-WS clients, must be measured carefully as it can be considered a small price to pay, compared to the impact we see if we make the coupling of the projects.
