p.put(Context.PROVIDER_URL, "t3://localhost:7001");

Context ctx=new InitialContext(p);
%>
get the Context!
<%
Object objRef=ctx.lookup("java:comp/env/ejb/Hello");
HelloHome home=(HelloHome)javax.rmi.PortableRemoteObject.narrow(objRef,HelloHome.class);
Hello bean=home.create();
%>
get the Hello EJB!
<%
out.print(bean.getHello());
}catch(javax.naming.NamingException ne){ out.print("NamingException");
}catch(javax.ejb.CreateException ce){ out.print("CreateException");
}catch(java.rmi.RemoteException re){ out.print("RemoteException");
}
%>
the end!
</body>
</html>

运行之后的结果:
get the Context! NamingException the end!
