But Emmanuel doesn't like that, so he won't give me a remote persistence unit. :-) Isn't it just a case of proxying the persistent context requests over remoting and making sure the request handling on the server side runs in any UserTransaction context created on the client? I think we can do that in the appserver without hibernate having to implement it. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4104200#...
