When using Persistence frameworks like Hibernate, JPA etc. on the server side, what are the general practices of passing on the data between client and server ? Are there any existing design patterns for the same ?
Thanks.
I do not know about patterns but I know in a design using for example EJB3 with JPA that it’s not recommended to pass JPA entities to client through remote EJB’s because proxies stay and it can generate a lot of useless network traffic. You’d better detach your entities or give to client simple value objects.
