lifecycle modules implement com.sun.appserv.server.LifecycleListener interface.
There is just one method in this interface: handleEvent() which posts server
lifecycle events to the lifecycle modules.
Upon start up, before initializing its subsystems application server posts lifcycle modules the
INIT_EVENT. This is followed by server posting the STARTUP_EVENT to the
lifecycle modules upon which server starts loading and initializaing the applications. Once this
phase is completed, the READY_EVENT is posted to the lifecycle modules.
When the server is shutdown, server posts the SHUTDOWN_EVENT to the lifecycle modules and
then shuts down the applications and subsystems. Once this phase is completed the
TERMINATION_EVENT is posted.
Note that lifecycle modules may obtain the event specific data by calling getData()
on the event parameter in the handleEvent(). For the INIT_EVENT event,
getData() returns the lifecycle module's properties configured in server.xml.
When is-failure-fatal in server.xml is set to true, all exceptions from the
lifecycle modules are treated as fatal conditions. |
