      String fileName = com.nstc.xxx.util.CqUtil.toGBK(request.getParameter("name"));
      if(fileName!=null&&filePath!=null){
          response.setContentType("application/x-download");
          response.addHeader("Content-Disposition","attachment;filename=" + java.net.URLEncoder.encode(fileName,"UTF-8"));
          try{
              RequestDispatcher dis = application.getRequestDispatcher(filePath);
              dis.forward(request,response);
              response.flushBuffer();
          }catch(Throwable e){
              e.printStackTrace();
          }finally{
          }
