How to make a form not running offline

[Arkab_Dev]

Hi, I've built my own form, which need to be submitted to a java servlet.

Is there a way to avoid that a user saves the pdf form and submit it when he shouldn't?

I've tryed with "preSave" event, but it cannot be canceled.

Any suggestions?

Thank you.

If the form is not reader extended, the user can save only a copy of the blank form (not with filled data), provided the end user should use only Adobe Reader.
