我的客户端是这么写的：

Properties properties = new Properties();

properties.setProperty(Context.INITIAL_CONTEXT_FACTORY,
"org.jnp.interfaces.NamingContextFactory");

properties.setProperty(Context.URL_PKG_PREFIXES,
"org.jboss.naming:org.jnp.interfaces");

properties.setProperty(Context.PROVIDER_URL, "jnp://localhost:8080");

Context context;
try {
context = new InitialContext(properties);
Object o = context.lookup("ejb/Hello");

HelloHome hwh = (HelloHome) PortableRemoteObject.narrow(o, HelloHome.class);
Hello hw = hwh.create();
String s = hw.sayHello();
System.out.println(s);
} catch (NamingException e) {
e.printStackTrace();
} catch (RemoteException e) {
e.printStackTrace();
} catch (CreateException e) {
e.printStackTrace();
}


}

没有相应的包，EJB需要很多包！
