Hi there, I am trying to get started with EJB3 and Seam and have a question regarding remote and local interfaces. It seems to define a stateful bean I have to do something along this lines: @Local public interface Foo { ... } @Stateful public class FooBean implements Foo { ... } I have to specify and interface which I annoate with @Local and then I need an actual bean implementation which I annoate with @Stateful. However, I thought that in EJB3 I don't need interfaces anymore. I hoped to be able to annoate a simple POJO. I recall reading somewhere that if eg I annotate a POJO as Stateful with no other annotation per default all public methods become part of the business interface. If I try to put the @Local annotation on FooBean itself removing the 'implements Foo' I get java.lang.RuntimeException: bean class has no local, webservice, or remote interfaces defined and does not implement at least one business interface Why are these interfaces still required. I could imagine something like this @Stateful public class FooBean implements Foo { @LocalMethod public void foo(); @LocalMethod @RemoteMethod public void bar(); } Why can I not annotate in a simple POJO which of my methods are exposed in the local/remote business interface. Of course I realize how much simpler EJB3 had become compared to EJB2, but without beeing able to annotate the buisness interface in the actual POJO it seems to be a half hearted apporach. Am I missing something? --Hardy View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3978601#...
