I agree with you about gilead intrusiveness. Also I see the project is not mantained any more. In my case I didn't get it to work, but google's using_gwt_with_hibernate.html document refer to it as a sollution. That is why I recommended it.
I will keep investigating Hibernate filter for future gwt+hibernate projects. Thanks for the info. Regards.
