Examples of java.net.URLClassLoader.findResource()

java.net.URLClassLoader.findResource()
Finds the resource with the specified name on the URL search path. @param name the name of the resource @return a URL for the resource, or null if the resource could not be found.

      URL url = null;
      // First check for local visibility via a URLClassLoader.findResource
      if( loader instanceof URLClassLoader )
      {
         URLClassLoader ucl = (URLClassLoader) loader;
         defaultUrl = ucl.findResource(defaultsName);
         url = ucl.findResource(propertiesName);
         log.trace("findResource: "+url);
      }
      // Do a general resource search
      if( defaultUrl == null )
