[jboss-user] [Beginners Corner] - How to handle configurable properties.

When I deploy my applications as an EAR there are certain properties that must change based upon the runtime environment such as the port of the Naming service or Production/Test environment settings. Basically those types of things normally put in a properties file. What is the best way to handle environment properties for my EAR applications?

Right now I see three approaches:
1. Use a regular old properties file and unzip EAR
2. Use a regular old properties file and deploy exploded EAR
3. putting some jndi bindings in the jboss-service.xml file

The problem I see with 1 is that if I had to make changes, I would have to unzip the EAR, make the change, and then re-zip it up. I want to be able to make configuration changes without disrupting the application.

Option 2 looks promising, but I am not sure if I change a value in the properties file when the EAR application will recognize the value change.

I have settled on option 3, but I think this requires that I restart JBoss whenever I make a change to the bindings. Is there a better way to handle environment properties? I want to know what my options are so I can do some more research, but for now I am not sure where to start.
