IBM MQ 9.1 教程三：远程访问IBM MQ队列

当应用程序不和IBM MQ的安装程序在一台主机上时，就需要通过IP远程访问IBM MQ队列了，此时可用TCP/IP协议

1. 在创建队列 管理器时，要勾选创建服务器连接通道

2. 创建一个本地队列Q1

3. 右键通道选项，新建服务器连接通道，名称SVRCONN.ONE

4. 代码访问示例，此示例访问windows上的IBM MQ，windows系统设置了用户名和密码

import com.ibm.mq.*;
import com.ibm.mq.constants.MQConstants;

public class MqDemo {

    private MQQueueManager qMgr;
    private MQQueue sendQueue;
    private MQQueue receiveQueue;
    private static int CCSID = 1381;

    public MqDemo() throws MQException {
