To start up customer java class or jar file when Java EE server starts. The solution usually is

1. Via WAR, servlet ; set the = 1 tag for servlet to provide intial invocation while the WAR is deployed.
Like this J2ee Start a class when application server starts

2. Depends on Java EE server setup.
For example, using weblogic startup and shutdown mechanism for EAR, In the weblogic-application.xml ; placed the following

//config xml

<startup>
<startup-class>MyStartup</startup-class>
<startup-uri>MyArchive.jar</startup-uri>
</startup>
<shutdown>
<shutdown-class>MyShutdown</shutdown-class>
<shutdown-uri>MyArchive.jar</shutdown-uri>
</shutdown>

I used second approach, so everytime I redeployed the EAR application the shutdown class main method was executed and then startup class invoked.

3. Using JBoss MBean service
