Question

Am researching the best way to load external properties files from and EJB 3 app whose EAR file is deployed to WebLogic.

Was thinking about using an init servlet but I read somewhere that it would be too slow (e.g. my message handler might receive a message from my JMS queue before the init servlet runs).

Suppose I have multiple property files or one file here:

~/opt/conf/

So far, I feel that the best possible solution is by using a Web Logic application lifecycle event where the code to read the properties files during pre-start:

import weblogic.application.ApplicationLifecycleListener;
import weblogic.application.ApplicationLifecycleEvent;

public class MyListener extends ApplicationLifecycleListener {
   public void preStart(ApplicationLifecycleEvent evt) {
      // Load properties files
   } 
}

See: http://download.oracle.com/docs/cd/E13222_01/wls/docs90/programming/lifecycle.html

What would happen if the server is already running, would post start be a viable solution?

Can anyone think of any alternative ways that are better?
