private static void read() {
try {
String source = "e:/12.xls";
InputStream is = new FileInputStream(source);
Workbook rwb = Workbook.getWorkbook(is);
// 获得总 Sheets
Sheet[] sheets = rwb.getSheets();
for (int i = 0; i < sheets.length; i++) {
for (int j = 0; j < sheets[i].getColumns(); j++) {
//获取指定单元格的对象引用，需要注重的是它的两个参数，第一个是列数，第二个是行数
Cell cell = sheets[i].getCell(j, i);
System.out.print("Values : " + cell.getContents().trim());
}
System.out.println();
} } catch (Exception e) {
e.printStackTrace();
}
}问题是：Sheet[] sheets = rwb.getSheets(); 这句获取不到所有行数，每次都长度都是1.指点下， 或者你有写好的给我也行。

是获得这个Excel文件中有多少个工作表啊！
楼主是想获取一个表中的所有行，Sheet rs = rwb.getSheet(0); rs.getRow();就是获得所有的行！
http://jexcelapi.sourceforge.net/resources/javadocs/current/docs/jxl/Workbook.html
这个的确是获得所有工作表
sheets[0]是第一张 再getRow 才是所有行
