Properties prop = new Properties();

            prop.put(Context.PROVIDER_URL, "remote://127.0.0.1:4447");

            prop.put(Context.SECURITY_PRINCIPAL, System.getProperty("username","user1"));

            prop.put(Context.SECURITY_CREDENTIALS, System.getProperty("password","12345"));

            prop.put(Context.INITIAL_CONTEXT_FACTORY, "org.jboss.naming.remote.client.InitialContextFactory");

                              final Context ctx = new InitialContext(prop);

                              Object ref = ctx.lookup("java:/eis/unionpayConnectionFactory");

                              unionpayConnectionFactory acf=(unionpayConnectionFactory)ref;

                              unionpayConnection ac=acf.getConnection();

when the code was runned,  there will be such a mistake:
