关于java excel api

[hanpannju]

import jxl.*;
import java.io.*;

public class ExcelReading {

public static void main(String args[]){
InputStream is = null;
Workbook rwb = null;
try {
System.out.println("2");
is = new FileInputStream(new File("D:\\abc.xls"));
rwb = Workbook.getWorkbook(is);
} catch (Exception e) {
System.out.println("找不到要求文件");
e.printStackTrace();
}
Sheet rs = rwb.getSheet(0);
Cell c00 = rs.getCell(0, 0);
System.out.println(c00.getContents());
}
}

头一回用这个api，想读取下excel文件，总是会出现这样的错误

检查一下你的编译环境，看看是不是1.5或以上？

是啊，但为什么编其他程序没问题呢[Quote=引用 1 楼 asparagus_fern 的回复:]
