Hi
I am executing the following programme and The excel contains macros for drop down

public static void main(String a[])
{
try
{
FileInputStream fis = new FileInputStream("D:/t/f/Headcoun.xls");

POIFSFileSystem pfs = new POIFSFileSystem(fis);
HSSFWorkbook book = new HSSFWorkbook(pfs,false);

} catch (FileNotFoundException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}



}
I am getting the exception as below
