两个加载方式的区别

URL[] urls = new URL[1];
      URLStreamHandler streamHandler = null;
      File classPath = new File(Constants.WEB_ROOT);
String repository = (new URL("file", null, classPath.getCanonicalPath() + File.separator)).toString() ;
urls[0] = new URL(null, repository, streamHandler);
loader = new URLClassLoader(urls);
myClass = loader.loadClass(servletName);

上述myClass是可以找到的

URL[] urls = new URL[1];
      URLStreamHandler streamHandler = null;
      File classPath = new File(Constants.WEB_ROOT);
urls[0] = new URL("file", null, classPath.getCanonicalPath() + File.separator);
loader = new URLClassLoader(urls);
myClass = loader.loadClass(servletName);

上述myClass找不到

查明原因？？见ServletProcessor1.process()
