You can deploy a lifecycle module using the following tools:
In the Administration Console, open the Applications component and go to the Lifecycle Modules page. For details, see the Sun Java System Application Server Enterprise Edition 8.1 2005Q2 Administration Guide.
Use the asadmin create-lifecycle-module command. For details, see the Sun Java System Application Server Enterprise Edition 8.1 2005Q2 Reference Manual.
After you deploy a lifecycle module, you must restart the server to activate it. The server instantiates it and registers it as a lifecycle event listener at server initialization.
If the is-failure-fatal setting is set to true (the default is false), lifecycle module failure prevents server initialization or startup, but not shutdown or termination.
