通过URL读取rss - java.net.ConnectException：连接超时：connect

Question

你好，我有一个问题，我想通过网站，我不能做的rss消费RSS。 例子：

System.setProperty("https.proxyHost", "proxy.example.local"); 
System.setProperty("https.proxyPort", "80"); 

DocumentBuilderFactory docBuilderFactory = DocumentBuilderFactory.newInstance(); 
DocumentBuilder docBuilder = docBuilderFactory.newDocumentBuilder(); 

URL url = new URL("http://pplware.sapo.pt/feed/"); 
InputStream stream = connection.getInputStream(); 
InputStream stream = url.openStream(); 
Document doc = docBuilder.parse(stream);  
System.out.println ("Root element of the doc is " + doc.getDocumentElement().getNodeName()); 

错误：

java.net.ConnectException: Connection timed out: connect 

我需要帮助IBM的网站和论坛，本次搜索，并且不解决问题。 问候 乔奥·索萨

如果可以打开http://pplware.sapo.pt/feed/槽浏览器，你不需要是前两行：

System.setProperty("https.proxyHost", "proxy.example.local"); 
System.setProperty("https.proxyPort", "80"); 

有没有proxy.example.local。

，当然，删除行

InputStream stream = connection.getInputStream(); 

最终代码会

DocumentBuilderFactory docBuilderFactory = DocumentBuilderFactory.newInstance(); 
    DocumentBuilder docBuilder = docBuilderFactory.newDocumentBuilder(); 

    URL url = new URL("http://pplware.sapo.pt/feed/"); 
    InputStream stream = url.openStream(); 
    Document doc = docBuilder.parse(stream); 
    System.out.println("Root element of the doc is " 
      + doc.getDocumentElement().getNodeName()); 

它为我工作。
