my code is a simplest form of JPA-GWT integration... it is a demo app in a GWT presentation to achieve the fastest startup... don't expect it to apply complex patterns :)
BTW, as Rakesh's suggested tutorial states, you can use DTO pattern to play with "not-too-complex" domain models. In fact, i have used this pattern before in a project [1], which includes class referencing and list type members, and working not by accident ;) I didn't use lazy, so i didn't need any external complexity. Just made my domain objects serializable by using Dozer. that's all.... Project at [1] uses a light but relational domain model in which some hibernate specific types like PersistentList and PersistentSet is being generated at runtime. But as the above tutorial points, you can make your objects seralizable easily by using an API like Dozer as implemented in the project [2]. My suggestion is the same as the above tutorial. If you are not using a very complex domain model and lazy ability, don't make your application too complex and go on with DTO pattern+Dozer... It is really simple and fast... But, on the other hand, if you want to use advanced techniques like lazy loading, you should try some more complex solutions.
