I'm working on a tutorial for EJB3 and JAX-WS generation and I'm running into a problem returning any non-primitive result. In this example, I have an @Entity called Customer, and I'm exposing a @WebMethod called findCustomerByName which takes a String and returns a List of Customers whose names match that String. See implementation here:
