导出Excel文件用类CachedRowSet报错
我们的项目要部署到jdk1.4的版本上,我要生成Excel文件,但是下面的代码在安装了jdk1.6的机子上(我在MyEclipse里设置的jdk5.0)运行正常,但是在安装成jdk1.4以后就报异常,我怎么改才能解决,请教高手指点

java代码:

CachedRowSet crs = this.GetResult(sql);
  WritableWorkbook wwb = null;
  try {
  wwb = Workbook.createWorkbook(os);
  jxl.write.WritableSheet ws = wwb.createSheet("Sheet1",1);
  int i = 1;
  while (crs.next()) {
  for (int j = 1; j <= crs.getMetaData().getColumnCount(); j++) {
  String s = crs.getString(j);
  Label labelC = new Label(j-1, i, s);
  ws.addCell(labelC);
  }
  i++;
  }
异常:

  excel.getExcelResult(sql,response.getOutputStream());

------解决方案--------------------
你的包有没有导入呀?
看你的代码至少要导入两个包

------解决方案--------------------
就是Rowset.jar
多百度几次吧....
