Configuration Provider & Configuration

The ConfigurationProvider interface describes the framework’s configuration. By default, the framework loads its configurations via an XML document by using the StrutsXmlConfigurationProvider. The provider can be configured through a Dispatcher’s DispatcherListener.

Example

 static {
   Dispatcher.addDispatcherListener(new DispatcherListener() {
     ....
     public void dispatcherInitialized(Dispatcher du) {
         ConfigurationManager confManager = du.getConfigurationManager();
         confManager.addConfigurationProvider( ... );
     }
     ....
   });
 }
