title: setting polling frequency for jms queue in mule
body: <p>I have a requirement where I want to poll JMS queue every 5 minutes and consumes all messages that are there in the jms queue. I am trying to do this in mule as following :</p>
  
  <pre><code>        &lt;jms:inbound-endpoint queue="jmsqueue" exchange-pattern="one-way" &gt;
               &lt;properties&gt;
                    &lt;spring:entry key="pollingFrequency" value="100000" /&gt;
               &lt;/properties&gt;
          &lt;/jms:inbound-endpoint&gt;
  </code></pre>
  
  <p>Above code is working but its ignoring the pollingFrequency attribute.</p>
  
  <p>Can someone help me how to set the polling frequency for JMS queue in Mule?</p>
  
  <p>Above issue is resolved. But with my fix, I am getting below exception: </p>
