System services

• Each service should have a corresponding LifeCycle MBean registered
  with an ObjectName independant of the implementation (use the interface
  instead of the class name)

• Management services should always throw RuntimeException with a message
  compliant with the xml description

• Internationalisation

InstallationService:

loadNewInstaller

• unpack jar in a temp dir
• parse / validate the jbi descriptor
• if a component with the same name is already loaded (installed or not installed but with an installer loaded)
  fail the request
• create a directory for this installer
  check the component name first, then patterns with (component name + "." + index)
  until one non existing directory is found
• create / init bootstrap
• create and register the installer mbean

loadInstaller

• check for an already loaded installer and return it if found
• check that the requested component is installed
• create / init bootstrap
• create and register the installer mbean

unloadInstaller

• if the component is installed throw an exception
• locate the installer mbean
• if found, unregister it
• delete directory if requested
  if not possible to delete directory, put a ".delete" file at root
  these directories should be removed when container restarts

Installer

getInstallerConfigurationMBean

• query the bootstrap for the configuration bean name and return it

install

• call bootstrap onInstall / cleanUp sequence
• create the component (no lifecycle involved)
• save its state (SHUTDOWN)

uninstall

• check that the component is stopped and has no service units
• shutdown the component
• call bootstrap onUninstall / cleanUp sequence

ComponentLifeCycle

start

• if component is running, do nothing
• if component is shutdown, call init on its lifecycle
• call start
• persist state if not system restart
• if system restart,
  initialize all SUs (they become stopped)
  restore previous state (started, stopped or shutdown)

stop

• if component is shutdown, throw an exception
• if component is stopped, return
• if component is running,
  stop all service units
  call stop on component lifecycle
  persist state if not system shutdown

shutdown

• if component is running, stop it
• if component is stopped,
  shutdown all service units
  call shutdown on component lifecycle
• persist state if not system restart
