Sample Lifecycle Configuration

The following example shows a portion of the server.xml that defines a lifecycle listener.

<lifecycle-module>
<class-name>com.sun.ias.server.LifecycleListenerImpl</class-name>
<is-failure-fatal>false</is-failure-fatal>
<description>Sample lifecycle module</description>
<property>
<name>foo</name>
<value>fooval</value>
<property>
</lifecycle-module>

The following example shows a sample LifecycleListener implementation
