Do I have to use DTO if I use GWT + JPA?

[Warren Tang]

Some say transferring entities cross the wire may cause problems, e.g. lazy loading. 

But I feel reluctant to introduce DTO. It's boilerplate and it's not right.

I also looked at RequestFactory and it seems a solution. However I'm also using GWTP's command pattern, which doesn't seem to work with RequestFactory.

Is there any alternatives? Do I have to use DTO?

Lazy loading won't work on the client side as the JPA session is only
maintained on the server side and only detached objects are sent down
to the client. You would need to use DTOs and send the fully-loaded
domain objects to the client.

Thanks for your reply. I also read this:

It seems that I have to go DTO anyway.

Did you try GILEAD? It permits you to send Persistent entities over
the RPC.

You may find DataStoreGwt handy. It has lazy loading and does away
with DTO.

Thanks for your suggestions. I'll look into Gilead or something like
Hibernate Filter (though I use EclipseLink).
