Hi Tilman,
Thank you so much for your answer.
I cannot send you the pdf as it contains our customer data.
Could you please tell me how I can read these field annotations in java?
Also many times we see a form with PDF reader and when doing PDAcroForm
acroForm = docCatalog.getAcroForm(), acroForm is null. How can this happen?
Regards,
Bruno.
