不知道是什么原因？应该怎样来解决呢？
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：
代码如下:
function myunload(){
window.opener.callback_getPageData_table_list(1);
}
var res='';
if(res=='true')
{
sys_ajaxPost("/dxt/multi_sender.do?method=importmulti_sender&accountid=&excelpath=","",function(msg){
if(msg.result==true){
location.href="/tech-java/${ctx}/dxt/sms/multi_sender/multi_sender/result/true.html";
}else{
location.href="/tech-java/${ctx}/dxt/sms/multi_sender/multi_sender/result/false.html";
}
});
}
