Restart current application in Jetty

I deploy a web application on Jetty as a war.
Is there a way in which I can restart the currently running application on Jetty programatically?
Is there a Jetty configuration that can achieve this?

This is an attempt at solving this problem: https://github.com/giuliano108/jetty-manager

sudo -u username jetty-manager

Usage:
  jetty-manager jvms
  jetty-manager webapps <jvm> [ <webappfilter> ]
  jetty-manager threads <jvm>
  jetty-manager stop <jvm> <webappfilter>
  jetty-manager start <jvm> <webappfilter>
  jetty-manager restart <jvm> <webappfilter>
  jetty-manager (-h | --help)

Commands:
  jvms           Show the running JVMs (PID, name)
  webapps        Show the webapps hosted by <jvm> and their state
  threads        Show the total number of threads in the <jvm>

Arguments:
  <jvm>          JVM PID or regexp (matched against the JVM name)
  <webappfilter> regexp matched against the context path (URL)

Options:
  -h --help     Show this screen

There are 3 options.

  1. Use JMX

    Try enabling JMX via the jetty-jmx libs and configuration. Then poking around the options for the contexts or deployers to see if you can use JMX to manage the deployed contexts

  2. Create your own Server bean to manage the deployment / undeployment of the contexts

  3. Create your own AppProvider, provided to the DeploymentManager to programmatically control the installed contexts.
