jPDFNotes inside Oracle Forms

I've included jPDFnotes of qoppa software inside Oracle Forms.

I've build the Form from the image with two Forms buttons: Fill and Save. The Fill button reads a pdf (blob) from the database, encodes it with base64 and then sent it to jPDFNote. After editing the PDF document, adding text like EXPIRED and a red circle, it is possible to save the record back to the database by pressing the Save button.
