我有下面的代码..问题与SAX
System.setProperty("http.proxyHost","176.6.129.25") ;
System.setProperty("http.proxyPort", "8080") ;
Authenticator.setDefault(new MyAuthenticator());
//http://deadlock.netbeans.org/hudson/api/xml
*URL url = new URL("http://in8301782d:8080/api/xml");*
Document dom = new SAXReader().read(url);
for(Element job : (List<Element>)dom.getRootElement().elements("job")) {
System.out.println(String.format("Name:%s\tStatus:%s",
job.elementText("name"), job.elementText("color")));
}
此代码工作，如果我有http://deadlock.netbeans.org/hudson/api/xml取代，但它不与http://in8301782d:8080/api/xml工作。 Infact如果我在浏览器中键入相同的东西，它正在工作..如果我用IP地址替换主机名也不工作。
我得到的例外如下。
