title: How to send objects to a servlet from a submit form
body: <p>I'm currently working on a GWT project and have a form with enctype multipart/form-data to upload a document. To receive the submit request, I have a servlet in the server side.</p>
  
  <p>Now, I want to send an array of objects at the same time as sending the document with the submit form. The problem is that all information I want to send through the submit form, I need to put in a form field somehow ...</p>
  
  <p>I first thought of creating inputs programmatically with an iteration over the array of objects. However, I just cannot put an entire object in a TextBox ...</p>
  
  <p>I'm probably missing something very simple ...</p>
  
  <p>Thanks for your help !</p>
