I haven't read the article @ javaworld you're referring to and I don't really understabd your question.
But anyway, in EJB 3.0 the home interface is removed but still you need either a Local or Remote business interface or a web service interface to your bean class.
here's a good place to start: http://trailblazer.demo.jboss.com/EJB3Trail/
Thanks for you feedback Anders !
Sorry if I haven't been clear enough in my post.
If I have well understood what is required and what is not, the generated class is not correct because it's declared as an EJB without implementing Local neither Remote interface.
So without one of this interface, this EJB is useless.
Can someone confirm please ?
I will try to update the Hibernate tool Eclipse plugin and see if this change the generated class.
