No. Unless you programmatically add that information while creating the document. iText doesn't do that. I don't know if JasperReports does that. You should ask the JasperSoft guys. > 2) Is it, in any way, possible to change/customize the application field > DURING/BEFORE file creation? Of course, piece of cake! Although changing the producer line (for instance changing lowagie.com into iowagie.com) would break your right to use the software for free. > 3) Is it, in any way, possible to change/customize the application field > AFTER the file was created? Of course, piece of cake! Unless of course you've added a digital signature. In that case, changing those values would invalidate the signature. > 4) Is it, in any way, possible to change/customize the created/modified > date field DURING/BEFORE file creation?

Why would we do that? Why are you asking this here? You're using JasperReports, why don't you ask them? You're talking about PDF, why don't you ask Adobe? -- This answer is provided by 1T3XT BVBA http://www.1t3xt.com/ - http://www.1t3xt.info ------------------------------------------------------------------------------ SOLARIS 10 is the OS for Data Centers - provides features such as DTrace, Predictive Self Healing and Award Winning ZFS.
