Do these strings need to change dynamically without app redeployment?
If it's just error messages and the like, why not use
java.util.ResourceBundle?
String msg = ResourceBundle.getBundle("mymessages").getString(MSG_KEY);
You can store the resources in any format you like if you implement your
own ResourceBundle subclass, or you can use a .properties file. If you
pass in the cool Orion classloader I believe it will dynamically reload
the data, too. Check the javadocs.
