Edit the pdf embedded in the browser and save the pdf directly on the server

I have this workflow.

  • Download the pdf file containing the form fields in the browser (pdf in iframe or div).
  • User fills it
  • Click the submit button (in another div) to save the PDF file.

What I would like to do in # 3 is to collect all the data associated with the form fields and save the data in a database table. I do not want the user to save the pdf file on his local computer and upload it to the server. I would like to make it more convenient.

I am going to use Java / JSP / Servlet on the server side. I looked at itext, which seems to be popular / well known for processing a PDF file, but itext seems to be used to create / edit a PDF document, but I'm not sure if there is a way to have a function capable of editing a pdf file embedded in browser, and save it to the database.

Is there any adobe software that provides some function that I can insert some kind of script that can capture the user? I know that PDF is not a scripting language interface, but I'm just asking.

I was going to create an HTML form that looks like this PDF file and fills it in PDF when the user clicks the submit button, but, as I said, I would like to make it more convenient.
