1. Сonsider binding a custom configuration object to JNDI. Then lookup this object in your apps to configure them. Benefits - you can use custom configuration object instead of rather generic Map or Properties.
2. Another way is to use JMX to configure applications you need. Benefits - you can bind objects you have to configure directly to MBean Server and then use such a well-known tools as jconsole or visualvm to configure components of your application.

Both ways support dynamic reconfiguration of your applications at runtime. I would prefer using JMX.
