Calling a method on ear deployment.

Question

Hi,
Our application needs to do some pre-processing when the application ear file is first deployed.
Is it possible to execute custom code when a particular ear file is deployed to application server? I looked around and found few ways to do it, none of them worked as specified. I would appreciate any help.
Following are the suggested methods .
1. Include a servlet in the ear file that loads on startup and put the custom code in the init method. I tried this but even though I specify load-on-startup to 0 in web.xml, the init method doesn't get called when the app server starts, (it gets called when first time the servlet is accessed from a browser).
2. The second option suggested was to create a client application in the ear file that has main method and specify in orion-application.xml
<client-module path="client.jar" auto-start="true" user="anonymous" />
(In the test case that I made, the client.jar has a single class that has a main method that prints a message. I also made sure that the manifest.mf file in client.jar has the class name specified for Main-class property and there is an application-client.xml file in this jar file). However, the main method didn't get called when I deployed the ear file as the document suggested.
Any help in this regard is very much appreciated.
Thanks,
prashant.
