I have just run the Telephone example successfully, using IBM WebSphere Application Server V4.0 (Advanced Developer Edition for Windows NT).
To fix your problem I think what you need to do is unzip Telephone.jar from the supplied TaminoEjbExampleTelephone.jar. Then you add the Telephone.jar to your application as an EJB module with the Application Assembly Tool Application Wizard, generate and everything works fine.
I tried to generate directly using TaminoEjbExampleTelephone.jar, and I get slightly different errors to you:
ejbModule/ejb/session/stateful/EJSRemoteStatefulTelephoneHome.java(9): ejb.session.stateful.TelephoneHome cannot be resolved or is not a valid superinterface
ejbModule/ejb/session/stateful/EJSRemoteStatefulTelephoneRemote.java(9): TelephoneRemote cannot be resolved or is not a valid superinterface
Hope this helps…
