      </h2>
      <hr><p> The &lt;a4j:push&gt; component performs real-time updates on the client side from events triggered at the server side.
      The events are pushed out to the client through the RichFaces messaging queue (which is bound to Java Messaging Service -
      JMS). When the &lt;a4j:push&gt; component is triggered by a server event, it can in turn cause Ajax updates and changes. </p>
