Apache POI 3.5 have added support to all the OOXML (docx, xlsx, etc.)

See the XSSF sub project

Answer 2

Might be a little late, but the beta POI now supports xlsx.

Answer 3

Aspose.Cells for Java supports XLSX format. You may find more details and further help in Aspose.Cells for Java Documentation. Please see if this helps.

Disclosure: I work as developer evangelist at Aspose.

Answer 4

AFAIK there are no xlsx-libraries available yet. But there are some for old xls:

One library is jxls which internally uses the already mentioned POI.

2 other links: Handle Excel files, Java libraries to read and write Excel XLS document files.

Answer 6

If you want to work with xlsx, you'll have to use the org.apache.poi.ss package. This package has class XSSF, which can be used for parsing xlxs file. This Sample code works on Excel 2007 or later (.xlsx)

OPCPackage pkg = OPCPackage.open(new ByteArrayInputStream(data));
            Workbook wb = new XSSFWorkbook(pkg);
            Sheet sheet = wb.getSheetAt(0);
            Iterator<Row> rows = sheet.rowIterator();

        while (rows.hasNext()) {
            int j = 5;
            Person person= new Person ();
            Row row = rows.next();
            if (row.getRowNum() > 0) {
                person.setPersonId((int)(row.getCell(0).getNumericCellValue()));
                person.setFirstName(row.getCell(1).getStringCellValue());
                person.setLastName(row.getCell(2).getStringCellValue());
                person.setGroupId((int)(row.getCell(3).getNumericCellValue()));
                person.setUserName(row.getCell(4).getStringCellValue());
                person.setCreditId((int)(row.getCell(5).getNumericCellValue()));
            }

        }

Excel 1998-2003 file (.xls) - you may use HSSF library.
  just use :  Workbook wb = new HSSFWorkbook(pkg);
