Lists the contents of the resource path.

Specified by:

list in interface ClassPathListing

Parameters:

context - the context to load the resource from the class path.

resourcePath - the path to the resource whose contents is to be listed. The empty string returns the contents of the class loader's root directory (which is usually the parent class loader's root).
