java操作xls

[zsjzlcxlh]

File file = new File(fileName1.toString().trim());
rwb = Workbook.getWorkbook(file);

这两行代码想要获取一个xls对象.调试之后,file没错的,但是调试到第二行的时候rwb一直为null...不理解?请大家帮忙

FileInputStream fis = new FileInputStream("F://data/1.xls");
HSSFWorkbook workBook = new HSSFWorkbook(fis);

[msg_java2011]

Workbook xlsWorkbook = null;
InputStream is = null;
if(fileFileName.toUpperCase().endsWith(".XLS")) {
is = org.apache.commons.io.FileUtils.openInputStream(file);
xlsWorkbook = Workbook.getWorkbook(is);}

你要先判断xml中的元素是否存在，再进行解析，呵呵，我刚在做这样的项目，你要是想要代码的话，我可以给你参考噢~~~
