XML文件解析的问题--大家帮帮忙吧!

已经存在 2006-02-27 10:54:45

Vector Parse(File f) /////////////传入文件时
{

try
{
// 创建一个document builder factory
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
// 设置factory 的参数
dbf.setValidating( false );
dbf.setNamespaceAware(false );
// 从factory 创建一个document builder
DocumentBuilder db = dbf.newDocumentBuilder();
// 导入xml 文件, 返回一个DOM Document 对象
Document doc = db.parse( f ); ////??????
// 遍历DOM Document 对象
this.fileParse(doc);
}
catch( Exception e )
{
e.printStackTrace();
}
... ...
}

我再解析XML文件时用到了以上的一个方法,最开始用的是Intellij IDEA 5.0编写的,
在Win 2003的系统上,正常运行;但现在拷到另一台Win 2000的机器上,用Intellij IDEA 4.0
打开该Project在运行时,总在////??????出现了以下的异常:
我前后都是用的j2sdk1.4.2,XML文件可以保证没错的.
查了些资料还是没解决,希望大家能给点帮助啊!小弟在此先谢过了!!!
