Yes you do. A client looks up the bean in JNDI, getting a reference to
its home interface, then calls 'create' or 'findByXXX' methods on it.

Please do.
InitialContext ctx = new InitialContext();
Object o = ctx.lookup("ClientManager");
ClientManagerHome clientHome =
(ClientManagerHome)PortableRemoteObject.narrow(o,
ClientManagerHome.class);
clientManager = clientHome.create();
Note use of the Home interface and the call to the create method.
