Reading the contents of excel sheet in Webdynpro java 7.3

Hi All,

I have a requirement where in i want to read the contents of the Excel file in portal. I could see the links for excel file upload for NWDS 7.0 but i am facing some issues in using the same thing in NWDS 7.3. Can any one help me out in achieving the same if any one has implemented the same in NWDS 7.3.

Please find the code am using and its not working

for reading the columns : int columns = sh.get columns( )

int rows = sh.get rows( ).

Thanks
