Thanks for your answer, Tilman, That was what I was afraid of: that the PDFBox workflow (or maybe moreso the PDF internal structures) are not documented, especially in the Javadocs ):
However, you did put me on the correct path and I was able to find something which may actually help: https://stackoverflow.com/questions/29371129/java-pdfbox-fill-out-pdf-form-append-it-to-pddocument-and-repeat I'll attempt to combine that strategy with PDDocument.removePage(0,2..7) as you suggested, though that seems like a lot of possible file pointers. Thanks! -----Original Message----- From: Tilman Hausherr <[email protected]> Sent: Tuesday, July 24, 2018 11:39 PM To: [email protected] Subject: Re: PDFBox AcroForm: timeline? or how to make multiple copies of a page into one file? WARNING: This is an external email that originated outside of the WPS email system. DO NOT CLICK links or open attachments unless you recognize the sender and know the content is safe! Hi, The pages have only the widget annotations. The form fields are related to the document catalog. Each field has one or more widgets. So it's more tricky. The best would be to create a copy of the document and then delete pages.
