解决这个错误，需要在form表单里面加上加enctype=”multipart/form-data” 这个属性，不过表单请求传到另一个jsp或servlet里时，是不能用request.getparameter()来获取到各个表单元素的值的，如下：
<%@ page language="java" contenttype="text/html; charset=utf-8"
pageencoding="utf-8"%>
<%@ page session="false"%>
<%@ include file="/common/taglibs.jsp"%>
<%@ include file="/common/meta.jsp"%>
<%@ include file="/common/js.jsp"%>
<%@ page import="java.util.*"%>
<%@ page import="java.text.simpledateformat"%>
<%@ page import="sdcncsi.ict.util.syspara"%>
<%@page import="java.io.*,java.util.*,sdcncsi.ict.base.attachment.*"%>

string savedirectory = "";
//获取配置参数,文件类型,文件大小
/*string date = "";

filefuns filefuns = new filefuns();

string file_type=syspara.getvalue("dxt_sms_multi_sender_file_type");

out.println("alert('错误：文件类型错误！');");
out.println("</script>");

filefuns.createdir(file_path);
}
string file_size = syspara.getvalue("dxt_sms_multi_sender_file_size");
