关于weblogic下用jxl.jar包用的excel导出报，文件错误，某些数字格式可能丢失

用jxl.jar包做成的excel导出在tomcat下跑完成正常，但部署到weblogic上会报错，文件错误，某些数字格式可能丢失

jxl.jar只支持到office 03版本，如果出现上述的错误，可能是你上传的模板 有 问题，最好用金山办公的execl保存成03以下的版本，不要用office来保存成03版本，具体原因，不是很清楚，不过这方法很有效果

下面是用jxl.jar包做成的产品目录导出的代码：

public void productDirectoryDownLoadExecl(HttpServletRequest request,

   HttpServletResponse response) throws Exception {

  OutputStream os = response.getOutputStream();// 取得输出流

  response.reset();// 清空输出流

  response.setHeader("Content-disposition", "attachment; filename="

    + java.net.URLEncoder.encode("产品目录导出.xls", "UTF-8"));// toUtf8String("供应商评估明细模板.xls"));//

                 // 设定输出文件头

  response.setContentType("application/x-msdownload;charset=utf-8");// 定义输出类型

    .getHibernateTemplate()

    request.getSession().getServletContext().getRealPath("/")

      + "/business/template/download/product_library_product_directoryDB.xls"); // 读取模板
