Usage

From source file:org.shept.util.JarUtils.java

/**
 * Copy resources from a classPath, typically within a jar file 
 * to a specified destination, typically a resource directory in
 * the projects webApp directory (images, sounds, e.t.c. )
 * /*from w  ww.  jav a 2s  . c  o m*/
 * Copies resources only if the destination file does not exist and
 * the specified resource is available.
 * 
 * The ClassPathResource will be scanned for all resources in the path specified by the resource.
 * For example  a path like:
 *    new ClassPathResource("resource/images/pager/", SheptBaseController.class);
 * takes all the resources in the path 'resource/images/pager' (but not in sub-path)
 * from the specified clazz 'SheptBaseController'
 * 
 * @param cpr ClassPathResource specifying the source location on the classPath (maybe within a jar)
 * @param webAppDestPath Full path String to the fileSystem destination directory   
 * @throws IOException when copying on copy error
 * @throws URISyntaxException 
 */
