I'm one of the maintainers of OpenPDF. Please give it a try and post your feedback. Also, if you are using iText 1.2.x, it's time to update to OpenPDF, which should be compatible.
Is there a version of PDFtk based on OpenPDF? PDFtk's original GCJ-compiled iText isn't well supported any more.
Thanks for the suggestion. I have forwarded this request to Sid in PDF Labs.
Great work, thank you for the effort you have put into this.
Is it possible to digitally sign a PDF with OpenPDF? If yes is there a tutorial somewhere or could you give a hint on how it's done or where to look at the Java API? Thanks in advance!
