I am generating an editable PDF form at the server side and sending it to the browser. At the client side, I am saving the PDF and adding the fields and submitting it via Acrobat Reader. Now once the servlet has read the form fields, I wan to send a success response back to the Acrobat Reader letting the user know that the form has been successfully submitted.
How do I send a response back to the Acrobat Reader as a java servlet response?
What do you want the end user to see?
In many cases, it's common to send a mail with either the link mentioned in (1) or the actual filled-out PDF.
Note that option (1) is only valid when you submit the form from a browser, using Adobe Reader / Acrobat as a plug-in. When using Adobe Reader / Acrobat as a standalone application, you'll have to use option (2) or (3), because Adobe Reader / Acrobat can't interpret HTML and will throw an exception saying that it has received content that can't be read.
