调用poi包访问xls文件的问题。急！！！送分50！！！

Question

我用java编写了一个组件，在这个组件中使用了poi包中的类访问excel文件，现在发现一个莫名其妙的问题，当访问一般的xls文件时都能正常处理，但是现在处理一个xls文件时却出现错误（这个文件是财务人员已经做好的模板，使用了宏，而且某些区域也添加了写保护）我是通过以下语句访问该文件的（经调试，fs对象创建成功，在创建wb对象时出错）。不知道该如何解决，请各位大侠指点一下啊！！
FileInputStream fileIn＝FileInputStream("001.xls")；
POIFSFileSystem fs＝new POIFSFileSystem(fileIn);
HSSFWorkbook wb=new HSSFWorkbook(fs); //出现错误行错误信息如下：
