how to intergrate GWT and JPA?

[cqiao]

I use myeclipse's reverse engineering to get entities and DAOs. but where to place the persistence.xml ?and if the web.xml needs to revise?

I get it! when add JPA capabilities, should select the persistence provider "hibernate", not "toplink" in myeclipse. all will ok! if select "toplink", must do something else (i don't know now).
