Tilman Hausherr commented on PDFBOX-3114:
-----------------------------------------

Unrelated but I'm trying to reach signature users:
Please have a look at PDFBOX-3065, this is about a different way to sign that 
will replace the current situation in 2.1, and in 2.0.* it will coexist. More 
explanation in {{PDDocument.saveIncrementalForExternalSigning}}, see [ 
https://svn.apache.org/r1759639 ].

> I tried to make two visible signatures in a 2-pages pdf file using 
> pdfbox-2.0.0-RC1.
> I followed the example in SVN directory
> https://svn.apache.org/viewvc/pdfbox/trunk/examples/src/main/java/org/apache/pdfbox/examples/signature/
> I have just modified CreateVisibleSignature class customizing the input 
> parameters and the page to sign.
> If both the signatures are made in the same page, no error occurs. If 
> signatures are made in different pages (e.g. signature 1 in page 1 and 
> signature 2 in page 2), when I open the pdf file with Adobe Acrobat XI Pro 
> (v.11.0.13) it tells that signature 1 is not valid.
> The attachment below refers to the source/resourse zip file. It contains:
> - test.docx: 2-pages test document generated with Microsoft Office 
> Professional Plus 2013
> - test1.pdf: pdf version that generates error (created with Word by selecting 
> "Save as Adobe PDF" option)
> - test1_*.pdf: signed pdf files with error
> - test2.pdf: pdf version that generates no error (created with Word by 
> selecting "Save as" option and then "*.PDF")
> - test2_*.pdf: signed pdf files with no error
> - CreateVisibleSignature.java: customized source code 
> - stamp.png: signature image
> - test.p12: key store (password 12345)
