Hi,
Can anybody help me in this issue, please ?
Yes, you should call HP and tell them their PDF has an inconsistency.
Please open your PDF in a text editor, and look at the first object (the one
with number 9):
9 0 obj
<<
/Author (Ian Dallow)
/CreationDate ()
/Creator (HP Digital Sending Device)
/ModDate (D:20130508044059+04'00')
/Producer (HP Digital Sending Device)
/Subject (testing)
/Title (test title)
>>
endobj
As you can see, the value for the CreationDate is an empty string, which is
EXACTLY what iText tells you when you ask iText for the CreationDate entry in
the Info dictionary (and it's very frustrating when people imply that there's a
bug in iText when iText is COMPLETELY CORRECT)!
Then why do you see a date when you open the PDF in Adobe Reader? Because
there's a CreationDate in the XMP data. Scroll to object number 4, and you'll
find a tag named CreateDate:
4 0 obj
<<
/Length 3652
/Subtype /XML
/Type /Metadata
>>

In other words: you're looking at the wrong place for the date! You need to get
the Metadata stream and parse it for the CreateDate.
