Re: With GWT, when exactly do you need DTOs for your entities ?

You will be needing DTOs if in entities there are any one to many
relationships.Or if you have any lazy load defined for any
fields.Since GWT can't serialize those objects, it will throw unable
serialize exception when you try to pass the entities from server to
client.
