When eXo Platform is running in the Dev mode, you can reload all the eXo containers, one given portal container or a set of portal containers.
Manual hot reloading
You can manually do the hot reloading for your eXo containers by using the JMX console and accessing the exo:container=root MBean
which provides 2 operations related to the hot reloading, including:
reload(): This method allows reloading all the containers (RootContainer included).
reload(String portalContainerName): This method allows reloading only one given portal container.
Automatic hot reloading
In the Dev mode, if a web application is redeployed for some reasons, the eXo Kernel will detect it.
If the web app is a valid extension which means that you defined the
org.exoplatform.container.web.PortalContainerConfigOwner listener in web.xml of this web app,
it will first check if the configuration of the RootContainer has changed.
If so, it will automatically reload everything. Otherwise, it will reload only the affected portal containers.
