org.jconfig.utils.ResourceLocator
njava.com/pub/a/onjava/excerpt/jebp_3/index1.html?page=3">Servlet Best Practices, Part 1 A class to locate resources, retrieve their contents, and determine their last modified time. To find the resource the class searches the CLASSPATH first, then Resource.class.getResource("/" + name). If the Resource finds a "file:" URL, the file path will be treated as a file. Otherwise, the path is treated as a URL and has limited last modified info. @author Andreas Mecky @author Terry Dye @author Steve Braun
