After this got sorted out with some kind help, I now continue to work on the same topic. Starting with doc_v2.pdf (links to the file are below!), I fill and sign it, resulting in doc_v2_fillsigned.pdf (doing it in one go, saving it incrementally). Again I open the edited document (using again PDFBox) and try to fill another field. Then saving the document leads to

I need to generate charts using JFreeChart and then export them to PDF using Apache PDFBOX . I don't want to use iText as it cannot be used in proprietary software.

A typical copyStream() implementation is shown here . Addendum: Alternatively, use piped streams to copy from output to input, as shown here and here . You can try using JasperReports . They are a bit heavy, but

I am currently using PDF Box to parse a pdf and I am trying to figure out how to retrieve data about the text such as the font (bold, size, etc) and the location of the font. Any suggestions? Mark Storer After poking around the (hard to find) PDFBox docs, I found this little gem . Apparently one of the examples shows exactly how to do everything you asked. Basically, you subclass PdfTextStripper and override the processTextPosition method. There, you query the TextPosition for whatever information you need. For future reference, you can find the javaDoc here: http://pdfbox.apache.org/apidocs
