> Currently, the method for locating resources (ie ConfigurationUtils.locate )
> uses a few means of finding the resource. However, the ways of finding resources
> are set in stone.
> At times, it would be useful to be able to pick and choose how resources are
> located. Here's an example:
> I have a webapp that builds a CompositeConfiguration composed of several

> or those files get used instead of the ones
> on the classpath that I intended to be used. As a result, unexpected behavior of
> the webapp ensues.
> The solution to this is to encapsulate each algorithm for locating resoucess,
> and be able to pick and choose. To me, this screamed of the strategy pattern.
> A patch is forthcoming...
