[诡异问题]vista下dom4j读取文件抛Connection timed out异常

[aunty_flybird]

问题如描述，很诡异的问题，拿出来和大家探讨。
Dom4j的版本是1.6.1

		SAXReader reader = new SAXReader();
		try {
			File xmlfile = new File(
					"E:\\workspz\\eclipse\\wafsrc\\target\\conf\\testng.xml");
			System.out.println(xmlfile.canRead());
			FileInputStream fis = new FileInputStream(xmlfile);
			System.out.println(fis.available());
			Document doc = reader.read(fis);
			System.out.println(doc);
		} catch (Exception e) {
			e.printStackTrace();
		}

上述语句执行时，打印如下：

true

Socket是DOM4j底层实现上的调用

[aunty_flybird]

怀疑是和vista的安全管理有关，谁能给点建议呢，从哪个角度出发去解决这个问题

[schumiXsuse]

楼主解决了么？我也遇到了同样的问题

[schumiXsuse]

楼主可以把下面的代码片段加到你的方法中，这样dom4j就不会去拿DTD增加那些DOCTYPE的默认属性了。
reader.setFeature("http://apache.org/xml/features/nonvalidating/load-external-dtd", false);

不太明白，这个要怎么加呢？

[wangshan_ws]

reader.setFeature("http://apache.org/xml/features/nonvalidating/load-external-dtd", false);这里的路径找不到？？？

[leeya1017]

确实是高人
