read xls - before Excel 2007
try {

    java.io.BufferedInputStream in = new java.io.BufferedInputStream(
            new PRInputStream(file));

    // open HSSFWorkbook
    org.apache.poi.poifs.filesystem.POIFSFileSystem fs = new org.apache.poi.poifs.filesystem.POIFSFileSystem(
            in);

Excel 2007 or later
try {
