Howto write metadata to xls with hssf

[韩浩]

Dear sir,
I have a scenario that we need to add some messages to the metadata of xls 
files. 
We know that it is workable for xlsx with the following code:
        XSSFWorkbook workbook = new XSSFWorkbook(fis);         POIXMLProperties 
props = workbook.getProperties(); 


However, most of our files are xls. So, I need you help on how to add 
properties to xls files with hssf?
Thanks!
