dom4j的问题

Java code

  public Document getDocument(URL url) throws Exception {    Document document = null;     SAXReader saxReader = new SAXReader();      document = saxReader.read(url);    return document;  }

saxReader.read(url); 这个url指的是什么啊?

我写了个测试的.但是不好用, 不明白URL该写什么??

测试如下:

Java code

  public static void main(String[] args) throws Exception {    TestDom4j td = new TestDom4j();    URL url = td.getClass().getProtectionDomain().getCodeSource().getLocation();      System.out.println(url);    Document doc = td.getDocument(url);      }

出错了: org.dom4j.DocumentException: Error on line 1 of document file:/D:/workspace_j2ee/XML/build/classes/ : Content is not allowed in prolog. Nested exception: Content is not allowed in prolog.

[解决办法]
url指向一个xml文档
