Hi, Otherwise, you will get:
... org.apache.pdfbox.pdmodel.interactive.digitalsignature.visible.PDFTemplateCreator buildPDF INFO: stream returning started, size= 11019 Exception in thread "main" java.io.IOException: COSStream has been closed and cannot be read. Perhaps its enclosing PDDocument has been closed? at org.apache.pdfbox.cos.COSStream.checkClosed(COSStream.java:78) at org.apache.pdfbox.cos.COSStream.createRawInputStream(COSStream.java:126) at org.apache.pdfbox.pdfwriter.COSWriter.visitFromStream(COSWriter.java:1138) at org.apache.pdfbox.cos.COSStream.accept(COSStream.java:372) at org.apache.pdfbox.cos.COSObject.accept(COSObject.java:158) at org.apache.pdfbox.pdfwriter.COSWriter.doWriteObject(COSWriter.java:538) at org.apache.pdfbox.pdfwriter.COSWriter.doWriteBody(COSWriter.java:450) at org.apache.pdfbox.pdfwriter.COSWriter.visitFromDocument(COSWriter.java:1039) at org.apache.pdfbox.cos.COSDocument.accept(COSDocument.java:409) at org.apache.pdfbox.pdfwriter.COSWriter.write(COSWriter.java:1289) at org.apache.pdfbox.pdmodel.PDDocument.saveIncremental(PDDocument.java:1118) at CreateVisibleSignature.signPDF(CreateVisibleSignature.java:169) at CreateVisibleSignature.main(CreateVisibleSignature.java:256) Moreover. Two questions: 1) Once I got rid of that IOE (by moving options.close() after doc.saveIncremental(cos)), I found that the example produces a corrupted signed pdf. The Signature Panel says: Rev. 1: Signed by signer name Signature is invalid: There are errors in the formatting or information contained in this signature (support information: SigDict /Contents illegal data) Signer's identity has not yet been verified Signing time is from the clock on the signer's computer. Last checked: 2015.10.07 19:41:53 +02'00' Field: Signature1 on page 1 I couldn't find the reason for that. Any ideas about what's wrong with the example apart from that options closing? 2) After a while I decided to create my own example (SignPDFPoC) by combining trunk CreateSignature and CreateVisibleSignature. With my example, I get a valid pdf after signing. Strange, cause it is just a "mix" of those 2 trunk examples. However, the Signature Panel always shows: Field: Signature1 on page 1 I thought that PDVisibleSignDesigner.signatureFieldName was used for that purposes. But it does not seem to be the case. Moreover, for invisible signatures, no PDVisibleSignDesigner is used, so there must be a different way. So the question is: how can I set the value of "Field" shown by Signature Panel for both invisible and visible signatures? Br, Rafael
