用POI解析EXCEL文件报错,高人指点.
HSSFWorkbook workbook = null;
try
{
workbook = new HSSFWorkbook(new FileInputStream( "c:\\12.xls "));
}
catch (IOException e)
{
e.printStackTrace();
}
.....
执行下面一句时
workbook = new HSSFWorkbook(new FileInputStream( "c:\\12.xls "));
抛出异常:

高人指点,谢谢先!
[解决办法]
帮你顶！！！
[解决办法]
你excel里面是不是有下拉列表什么的东西啊 我用过jxl对这个不太熟悉 有问题再联系 lws.emmagee@163.com
[解决办法]
帮你顶，一直使用JXL。
[解决办法]
你看看你的版本，应该是版本问题
[解决办法]
你的excel文件的compound header没办法被poi识别，有很多种可能：
你的excel文件是第三方工具生成的，比如水晶等报表工具；
你的excel文件里面报表了一些特别的control，如按钮、vba等；
你的excel文件版本无法被poi识别，目前poi只是支持excel97-excel2003的biff8格式；
