Yup, POI is the way to go. If you use the classes in the org.apache.poi.ss.* packages (and NOT the ones in org.apache.poi.hssf or org.apache.poi.xssf) then you can work with both file formats. http://poi.apache.org/spreadsheet/quick-guide.html will get you going (just remember to use the proper package!).
