IBM MQ 使用出现问题

最近的项目中 要用到IBM MQ 。
写了四个接受类并实现了MessageListener监听，在servlet里面分别new 了四个类
在web 容器启动后 开始监听，但是出现的问题是 监听不到。

package com.founder.gome.bg.service.mq;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;

public class MQServerlet extends HttpServlet {
	private static final long serialVersionUID = 1L;
	

	TntListener jt3 = null;
	SnListener jt4 = null;


	@Override
	public void init() throws ServletException {
		jt3 = new TntListener();
		jt4 = new SnListener();
	    jt3.init();
	    jt4.init();

	@Override
	public void destroy() {
		if(jt3!=null) {
			jt3.distory();
		}
		if(jt4!=null) {
			jt4.distory();
		}
		super.destroy();
	}
	
	
	
}
