Want to set Jetty to hot deploy, but there is no deployer

I'm running a SmartFox 1.6 server with included Jetty servlet container. I want to configure Jetty to automatically deploy new web apps. Normally this is as simple as adding a scanInterval to the deployer:

<Call name="addLifeCycle">
  <Arg>
    <New class="org.mortbay.jetty.deployer.ContextDeployer">
      <Set name="contexts"><Ref id="Contexts"/></Set>
      <Set name="configurationDir"><SystemProperty name="jetty.home" default="."/>/contexts</Set>
      <Set name="scanInterval">1</Set>
    </New>
  </Arg>
</Call>

However, I can't find a deployer at all in the Jetty config file, pasted below. The config is the default config included with Smartfox.

Sorry for needing to include the entire config file, but I wouldn't know which blocks are relevant. Where can I set the scanInterval in the settings below?

you just need to add this Call to your config file.

Answering it here, in case anyone come across this thread. Hot deployment is possible in jetty, you need to specify interval, location etc. in jetty ini files, not in jetty-xmls. See below official jetty documentations https://www.eclipse.org/jetty/documentation/current/hot-deployment.html
