Life cycle modules, also known as initialization services, provide a means of running short or long duration Java-based tasks within the GlassFish Server environment. These modules are automatically initiated at server startup and are notified at various phases of the server life cycle. Configured properties for a life cycle module are passed as properties during server initialization.
All life cycle module classes and interfaces are in the as-install/glassfish/modules/glassfish-api.jar file.
A life cycle module listens for and performs its tasks in response to the following GlassFish Server sequence of events:
Initialization:
The server reads the configuration, initializes built-in subsystems (such as security and logging services), and creates the containers.
Startup:
The server loads and initializes deployed applications.
Ready:
The server begins servicing requests.
Shutdown:
The server shuts down the applications and stops.
Termination:
The server closes the containers, the built-in subsystems, and the server runtime environment.
