How to deploy ApplicationLifecycleListener - deployment

Question

I created an ApplicationListener extends ApplicationLifecycleListener in a java project, packaged as a jar file, create ear file contains this jar file, try to deploy it in the weblogic server with the "install" button in weblogic admin console(screenshot), I got error. If I pack it as a war file, create a ear file contains this war file, with the same approach I can deploy it with no error, but it does not being called.
I have searched on the internet for a while, a lot of people was talking about adding this listener to a weblogic-application.xml, I do not have this file in my project, I tried to find this in the weblogic server folders also can not locate it, I am new to weblogic, no idea how should I make a ApplicationLifecycleListener work.
Where should I find this weblogic-application.xml file? Or where do I need to create this file? Do I have to create a J2EE or EJB project? Or a java project can do this.
If possible please give me some detailed steps about deploying an ApplicationLifecycleListener. (I am using Jdeveloper)
First what project I should be using to write this listener class, and after coding, how to I register it, what is the best way and how should I deploy it.

In a typical maven EAR project, you'd put it in /myapp-ear/src/main/application/META-INF/, and it would look a bit like this:
<weblogic-application>
<listener>
<listener-class>com.myapp.SomethingSomethingServiceListener</listener-class>
<listener-uri>myapp-lib.jar</listener-uri>
</listener>
<!-- add whatever other things you'd normally put into weblogic-application-->
</weblogic-application>
Then /myapp-lib/src/main/java would have your listener code.
I like to put this code inside /myapp-ear/pom.xml but that's up to you:
<build>
<plugins>
<plugin>
<artifactId>maven-ear-plugin</artifactId>
<configuration>
<defaultLibBundleDir>APP-INF/lib</defaultLibBundleDir>
<modules>
<jarModule>
<groupId>com.myapp</groupId>
<artifactId>myapp-lib</artifactId>
<bundleDir>/</bundleDir>
</jarModule>
</modules>
<archive>
<manifest>
<addClasspath>true</addClasspath>
</manifest>
<manifestEntries><!-- weblogic really wants to know this for hot deploys -->
<Weblogic-Application-Version>${project.version}</Weblogic-Application-Version>
</manifestEntries>
</archive>
<fileNameMapping>no-version</fileNameMapping>
</configuration>
</plugin>
</plugins>
</build>
