[configuration]

[Lautaro Brasseur <lb...@yahoo.com>]

I'm trying to use the CompositeConfiguration class:

http://commons.apache.org/configuration/userguide/howto_compositeconfiguration.html#Setting_Up_Defaults


but I didn't found the method a=dDefaults referenced in that page. Is there any 
replacement?

Thanks in advance.

this example is wrong. The last line should run
cc.addConfiguration(fileToDefaults);

When asked for a property CompositeConfiguration searches all contained 
configuration objects in the order they were added. The first value 
found is returned. So you can achieve a defaults mechanism by simply 
adding the configuration with the default values as the last 
configuration: it is then queried if no other configuration object 
contains the property in question.
