THIS IS A TEST INSTANCE. ALL YOUR CHANGES WILL BE LOST!!!!
ConfigurationProvider is an interface that determines Struts2 Configuration. Struts2 loads its configurations through an xml by using StrutsXmlConfigurationProvider. This is configurable through Dispatcher's DispatcherListener. See here for more info regarding DispatcherListener.
Example
static {
Dispatcher.addDispatcherListener(new DispatcherListener() {
....
public void dispatcherInitialized(Dispatcher du) {
ConfigurationManager confManager = du.getConfigurationManager();
confManager.addConfigurationProvider( ... );
}
....
});
}
