关于lan.ClassNotDefFoundException (wrong name)错误

最近写《How tomcat work》中，有实现简单servlet容器时。

public class ServletProcessor1 {
    public void process(Request request, Response response){
        String uri = request.getUri();
        String servletName = uri.substring(uri.lastIndexOf('/')+1);
        URLClassLoader loader = null;
        try {
            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);
        }catch (Exception e){
            e.printStackTrace();
        }
        Class myclass = null;
        try {
            myclass = loader.loadClass(servletName);
        }catch (ClassNotFoundException e){
            e.printStackTrace();
        }
        Servlet servlet = null;
        try {
            servlet = (Servlet) myclass.newInstance();
            servlet.service(request, response);
        }catch (Exception e){
            e.printStackTrace();
        }

    }
}

此处加载类的时候一直抛出异常，原因是该类处于某个包下，而加载的时候没有使用pakage.class方式，而是用了pakege/class的方式。将loader.loadClass加载方式改为pakege.class正常运行。
