１.远程客户端：传值，对象必须序列化，服务器对对象的修改不会在客户端体现。
２.本地客户端：
（１）创建一个ｗｅｂ项目，与ｊｂｏｓｓ部署在同一个ＪＶＭ当中。
（２）添加服务器端项目的依赖或手动添加接口的ｊａｒ包
（３）在index.jsp改编码。
本地客户端也可以使用远程调用方式：
<%
Hashtable env=new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY,"org.jnp.interfaces.NamingContextFactory");
env.put(Context.PROVIDER_URL,"localhost:1099");
env.put("java.naming.factory.url.pkgs","org.jboss.naming:org.jnp.interfaces");
InitialContext cxt=new InitialContext(env);
UserManager us=(UserManager)cxt.lookup("UserManagerBean/remote");
User u=new User();
u.setUsername("persia");
u.setPassword("p");
us.addUser(u);
out.println("user--perisa已经创建。"+u.getId());
%>
本地客户端的本地调用方式没成功：

有待以后多些见识解决或偶遇高人指点。
不大清楚，本地调用还需要ＪＮＤＩ吗？
