什木啊，就是代码错啦，给你个例子自己好好看看···
不行就把你的代码贴上···
// 创建可写入的Excel工作薄
OutputStream os = new FileOutputStream("D:\\数据汇总分析表.xls");
WritableWorkbook workbook1 = Workbook.createWorkbook(os);
WritableSheet sheet = workbook1.createSheet("数据汇总分析表", 0);追问

这个错误不是一开始就有的，之前只是报内存溢出错误，我一修改jvm的参数，它才出现这个错误，所以绝对不是代码问题！而且后面验证这个内存溢出问题不是因为数据量大的问题，而是因为excel中运用了格式什么的原因，因为我把除了头部分的数据外全部copy到另外一个excel表中就没有了错误！

参考技术A 如果不是代码错误，就是jxl包的版本不够，更新jxl包的版本后再试试
若果仍然报错试试这个：
package jxl_excel;

import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.io.InputStream;

import jxl.Sheet;
import jxl.Workbook;
import jxl.read.biff.BiffException;

public class JxlExcel

/**
* @param args
* @throws IOException
* @throws BiffException
*/
public static void main(String[] args) throws BiffException, IOException
InputStream is = new FileInputStream("c:\\a.xls");//path是文件路径
Workbook wb = Workbook.getWorkbook(is);// 获得工作薄
Sheet st = wb.getSheet(0);
//获得总行数
int rowSize=st.getRows();
//获得总列数
int columnSize=st.getColumns();
if(rowSize!=0)
for(int i=1;i<rowSize;i++)
for (int j=0;j<columnSize;j++)
//st.getCell(j,i).getContents()括号内的参数j代表总列数，i代表总行数
System.out.println(st.getCell(j,i).getContents());

追答

可能是jvm参数修改错误导致的吧
