Yes.. I think it is possible .. the way I know you have to use a javascript library like jquery. Below is how it happens

是..我认为有可能..我知道你必须使用像jquery这样的javascript库。以下是它的发生方式

On form submit you prevent the post to servlet. Then you can use ajax like shown below to send 2 requests to 2 different servlets. Below shows one ajax call.. you can do another after that call. I trying to show you below

在表单提交上,您可以阻止发布到servlet。然后你可以使用如下所示的ajax向2个不同的servlet发送2个请求。下面显示了一个ajax调用..在调用之后你可以做另一个。我想告诉你如下

$("form").submit(function(evt){  
      evt.preventDefault();
      var formData = new FormData($(this)[0]);
      var author = $("#author").val();
   $.ajax({
       url: 'fileUploadServletUrl',
       type: 'POST',
       data: formData,
       async: false,
       cache: false,
       contentType: false,
       enctype: 'multipart/form-data',
       processData: false,
       success: function (response) {
         alert(response);
       }
   });

   $.ajax({
       url: 'textDataServletUrl',
       type: 'POST',
       data: {'author':author },
       async: false,
       cache: false,
       processData: false,
       success: function (response) {
         alert(response);
       }
   });

   return false;
 });
