Because Home interfaces must return local/remote interfaces, and local/remote must extend EJBLocalObject/EJBObject.

Let's draw up some definitions first, because the wording in the spec is a little tricky. * Business Interface - The EJB3 View, may be local or remote, and is denoted by the corresponding @Local and @Remote annotations. * Remote Interface - The EJB2.x View, must extend from EJBObject, may only be obtained via the return of a create{METHOD} method of a Home interface (for SFSB) or the "create" method of a Home interface (for SLSB). See Spec 3.6.2. So in regards to 4.6.6, they're talking only about *Business* interfaces, yes, saying that a business interface cannot also be a remote/local interface. My solution to these tests is to make: public interface MyStatefulRemote extends EJBObject{...} | | public interface MyStatefulRemoteBusiness{...} | | public interface MyStatefulRemoteHome extends EJBHome{ | public MyStatefulRemote create() throws CreateException, RemoteException; | } | | @Stateful | @RemoteHome(MyStatefulRemoteHome.class) | @Remote(MyStatefulRemoteBusiness.class) | public class MyStatefulBean implements MyStatefulRemoteBusiness{...} S, ALR View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4152529#...
