xml编码问题 org.xml.sax.SAXParseException: Invalid byte 1 of 1-byte UTF-8 sequence.

org.xml.sax.SAXParseException: Invalid byte 1 of 1-byte UTF-8 sequence.
这个问题的解决：

// 生成的xml的格式
OutputFormat format = OutputFormat.createPrettyPrint();
// 生成的xml文档路径
String path = "D:/Documents and Settings/Administrator/workspace/GDS/config/graph/gisproducts/S002.xml";

把：
XMLWriter writer = new XMLWriter(new FileWriter(path), format);

改成如下：就可以了
XMLWriter writer = new XMLWriter(new FileOutputStream(path), format);

写的够简洁吧，呵呵！
