Re: What do I add the ApplicationLifecycleListener to?

I need to be able to perform some things when our app gets deployed and

a listener?Your ApplicationLifecycleListener class needs to be in the $CLASSPATH or
APP-INF/lib or APP-INF/classes. I'd suggest APP-INF.
You then need to declare your listener in your ear's
META-INF/weblogic-application.xml descriptor. Here's an example:
<!DOCTYPE weblogic-application PUBLIC '-//BEA Systems, Inc.//DTD
WebLogic Application 8.1.0//EN'
'http://www.bea.com/servers/wls810/dtd/weblogic-application_2_0.dtd'>
<weblogic-application>
<listener>
<listener-class>com.bea.applife.Listener</listener-class>
</listener>
</weblogic-application>
And how does it get created before my app is even deployed?It's probably more accurate to say that it's the first thing called
during deployment. Essentially the application files are distributed to
the managed servers, application-wide classloaders are established etc,
and then the preStart callback is called on any listeners before the
Modules (eg webapp, ejb etc) are initialized.

In general, the classes in APP-INF/classes can reference other classes
loaded by the application classloader. This commonly includes jar files
in APP-INF/lib and EJBs. By default, classes in web-applications are
loaded by child classloaders so they would not be seen.

This APP-INF is new to me so I'll have to look into that. Are there any
issues with something in APP-INF/classes refering to other classes in my
EAR?
