Reading/Writing .xlsx files using Webdynpro for Java

Question

Dear All
I have a requirement to read/write excel files in .xlsx format. I am good in doing it with .xls format using jxl.jar. The jxl.jar doesn't support .xlsx format. Kindly help me in understanding how do I need to proceed on reading/writing .xlsx files using Webdynpro for Java.
Thanks and Regards

i am using jdk 1.6.22 and IBM WebSphere
when i use poi-3.6-20091214.jar and poi-ooxml-3.6-20091214.jar  to read .xlsx file. but i am getting following errors
The project was not built since its classpath is incomplete. Cannot find the class
file for java.lang.Iterable. Fix the classpath then try rebuilding this project.
This compilation unit indirectly references the missing type java.lang.Iterable
(typically some required class file is referencing a type outside the classpath)
how can i resolve it
here is the code that i have used
public class HomeAction extends DispatchAction {
     public ActionForward addpage(
                         ActionMapping mapping,
                         ActionForm form,
                         HttpServletRequest request,
                         HttpServletResponse response)
                         throws Exception {     
                         String name = "C:/Documents and Settings/bharath/Desktop/Book1.xlsx";
           FileInputStream fis = null;
           try {
               Object workbook = null;
                fis = new FileInputStream(name);
                XSSFWorkbook wb = new XSSFWorkbook(fis);
                XSSFSheet sheet = (XSSFSheet) wb.getSheetAt(0);
                Iterator rows = sheet.rowIterator();
                int number=sheet.getLastRowNum();
                System.out.println(" number of rows"+ number);
                while (rows.hasNext())
                    XSSFRow row = ((XSSFRow) rows.next());
                    Iterator cells = row.cellIterator();
                    while(cells.hasNext())
                XSSFCell cell = (XSSFCell) cells.next();
                String Value=cell.getStringCellValue();
                System.out.println(Value);
           } catch (IOException e) {
                e.printStackTrace();
           } finally {
                if (fis != null) {
                     fis.close();
            return mapping.findForward("returnjsp");
