■高分请教■：为何我的程序中的XML总是上internet访问DTD文件？如何阻止？

[vipcowrie]

我的XML头部如下：

<?xml version='1.0' encoding='gb2312'?>
<!DOCTYPE hibernate-configuration SYSTEM "http://hibernate.sourceforge.net/hibernate-configuration-2.0.dtd">

每次启动程序加载这个文件的时候，它总是试图去那个网址访问dtd文件，
如果没有访问到，就不能正确加载XML文件，它使用的XML解析工具市DOM4J，
请教高手，如何解决！

异常如下：

下载http://hibernate.sourceforge.net/hibernate-configuration-2.0.dtd
放于本地，并修改
<!DOCTYPE hibernate-configuration SYSTEM "http://hibernate.sourceforge.net/hibernate-configuration-2.0.dtd">
路径

谢谢 saucer(思归/MVP) 以及 IMarksman(唉！为什么总是睡不醒呢？)，我已经成功的解决了这个问题，谢谢。结贴了。

try to disable it like


String feature =
"http://apache.org/xml/features/nonvalidating/load-external-dtd";;
SAXReader reader = new SAXReader();
reader.setFeature( feature, false );


or implement a EntityResolver, see
