跪求jxl合成多个sheet的程序

[卧石听泉]

跪求jxl合成多个sheet的程序，大师们，给我一个吧，我郁闷啊
我写了个，可出现数据串的情况，比如，四个单excel单sheet，合成一个excel四个sheet ，sheet1和数据sheet4出现错位，不明白，大师，请指点

import jxl.Workbook;
import jxl.write.Label;

import jxl.write.WritableWorkbook;

import com.domain.ExcelMergeParamVo;

public class ExcelEmrger {

public static void main(String[] args) {
Map<String, String> subFiles = new HashMap<String, String>();
/*subFiles.put("rate_summary.xls", "rate_summary");
subFiles.put("gsm_rate.xls", "gsm_rate");
subFiles.put("gprs_rate.xls", "gprs_rate");
subFiles.put("sms_rate.xls", "sms_rate");
subFiles.put("ss_rate.xls", "ss_rate");*/
subFiles.put("custuserstat.xls", "custuserstat");
subFiles.put("custuserstat1.xls", "custuserstat1");
ExcelMergeParamVo paramVo = new ExcelMergeParamVo();
paramVo.setFileName("emergerExcel.xls");
paramVo.setSubFiles(subFiles);
paramVo.setDirPath("D:\\report_path\\");
String message = doEmergerExcel(paramVo);
System.out.println(message);

}

@SuppressWarnings("unchecked")
public static String doEmergerExcel(ExcelMergeParamVo paramVo) {
String message = "合成成功";// 定义返回消息
WritableWorkbook wwb = null;
Map<String, String> subFiles = paramVo.getSubFiles();

message = "参数设置不正确";
return message;
}
Iterator keyValuePairs = subFiles.entrySet().iterator();// 文件名
try {

while (keyValuePairs.hasNext()) {
Map.Entry<String, String> entry = (Map.Entry) keyValuePairs.next();
String key = entry.getKey();
String value = entry.getValue();
InputStream is = new FileInputStream(paramVo.getDirPath() + key);
Workbook rwb = Workbook.getWorkbook(is);

label.setCellFormat(format);
sheet.addCell(label);
}
}
}
rwb.close();
}
wwb.write();
wwb.close();
} catch (Exception e) {
e.printStackTrace();
message = "合成失败";
return message;
}
return message;
}
}

这自己写完全可以吧！
