用ajax发送jms讯息监听指定队列并从中取出消息的小例子 _Ajax

用ajax发送jms消息监听指定队列并从中取出消息的小例子
1.下载 apache-activemq-5.3.0-bin.zip

2.下载例子 jsmqtest.rar

3.用eclipse 打开   jsmqtest 工程，并把 D:\apache-activemq-5.3.0\lib中的jar导入

4.启动 D:\apache-activemq-5.3.0\bin\activemq.bat

5.打开 http://127.0.0.1/jsmqtest/index.htm页面

6.开始测试吧

说明：

1.引入activemq-web-5.3.0.jar 包，里面有封装好的AjaxServlet ； _amq.js； amq.js；behaviour.js

2. 配置 D:\jetty-6.1.7-atf\webapps\jsmqtest\WEB-INF\web.xml

    添加

   <context-param>
      <param-name>org.apache.activemq.brokerURL</param-name>
      <param-value>tcp://localhost:61616</param-value>
   </context-param>

   <servlet>
      <servlet-name>AjaxServlet</servlet-name>
      <servlet-class>org.apache.activemq.web.AjaxServlet</servlet-class>
</servlet>

<servlet-mapping>
    <servlet-name>AjaxServlet</servlet-name>
    <url-pattern>/amq/*</url-pattern>
</servlet-mapping>
3.在html页面增加监听方法，用于监听jms中间件消息，jms队列可以是 topic 也可以是queue；

4.启动web服务器和jms服务器

5.打开 http://127.0.0.1/jsmqtest/index.htm页面只要jms“queue://mqtes”队列中有消息，html页面就会自动显示出来。

6.开始测试吧

可以用了，发送一条消息后，得刷新页面！后天还报错
