jxl应用中的一个问题.

[fush76]

运行环境: WIN2003+tomcat 5.5


用jxl 写入xls 时,页面报错(已将 jxl.rar 包,已放到了 ROOT/WEB-INF/lib 目录.),
1.报错信息如下:
type Exception report

message

description The server encountered an internal error () that prevented it from fulfilling this request.

exception

org.apache.jasper.JasperException: Unable to compile class for JSP:

An error occurred at line: 46 in the jsp file: /tmp_test.jsp
WritableWorkbook cannot be resolved to a type
43: //WritableSheet sheet = workbook.createSheet("First Sheet", 0);
44:
45: OutputStream os=new FileOutputStream("D:\\fuck_yy.xls");
46: WritableWorkbook wwb=Workbook.createWorkbook(os);
47: WritableSheet ws=wwb.CreateSheet("sheet",0);
48:
49:

2. jsp内容如下:

String fileName = "abcd.xls";

response.reset();
response.setContentType("application/vnd.ms-excel");
response.addHeader("Content-Disposition","attachment;filename=" + fileName);
//Excel.export(response.getOutputStream(), "", rs, map);


//WritableWorkbook是JexcelApi的一个类。
//以下可以理解为创建一个excel文件，然后在excel里面创建一个表
// OutputStream os = response.getOutputStream();//取得输出流
//WritableWorkbook workbook = Workbook.createWorkbook(os);
//WritableSheet sheet = workbook.createSheet("First Sheet", 0);

OutputStream os=new FileOutputStream("D:\\fuck_yy.xls");
WritableWorkbook wwb=Workbook.createWorkbook(os);
WritableSheet ws=wwb.CreateSheet("sheet",0);


Label labelCF=new Label(0,0,"hello"); //创建写入位置和内容

sheet.addCell(labelCF); //将Label写入sheet中.
workbook.write();
workbook.close();
os.close;

%>

[系统信息]

放的是jxl.rar还是jxl.jar？
