This week's book giveaways are in the Refactoring and Agile forums. We're giving away four copies each of Re-engineering Legacy Software and Docker in Action and have the authors on-line! See this thread and this one for details.
Does anyone know if there is any jar by support of which we can write code supporting creation of both formats .xls and .xlsx (APache jar...POI i know)?
Implementation would be a better solution.

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!).
