Hi Rafael, That is correct. Any widgets or POJOs you would like to use on the client-side must have their source available for the GWT compiler to see, optimize and cross-compile it. However, since you mentioned that the classes you want to reuse are ORM generated and a little more than POJOs, you still might not be able to use those classes in your client-side GWT code.
The thing to keep in mind is that GWT code gets cross-compiled to JavaScript. This means that anything you write in your GWT code must have some rough equivalent in the JavaScript world. This makes sense for things like java.util.Map and java.util.List, but less so for things like java.io.FileWriter or java.util.Semaphore. The list of types that GWT supports from the JRE world can be found in the Emulated JRE documentation (link below). This means that as long as the ORM generated classes only use types that are supported in the Emulated JRE, you should be able to use them on the client-side GWT code. If not, you'll have to create your own data transfer objects (DTOs) or you might want to look into the Gilead project, which provides a way for reusing ORM types seamlessly in your GWT code. Many developers have been using this library to integrate with Hibernate, which also does its own class generation and has its own inheritance hierarchy for certain types mapped to the database.
