Adobe's LiveCycle product family (especially Reader Extension Server) is what one would use in this instance to enable each PDF generated by iText. We have numerous customers that use tools such as iText to produce the documents but then enable them with LCRES - no big deal.
No, an ISO 32000-1 conforming reader that doesn't care can happily ignore it (and in fact, should ignore it). It's just a standard PDF with some "extra stuff" - another reader can (and will) just fill the document in. HOWEVER, as iText users have seen on this list, if you do NOT fill it in correctly, then you will "break" the extensions. That may not be a problem in some workflows, but it is in others. As far as Adobe and ISO 32000-1 is concerned - doesn't matter. Adobe isn't the only company that uses this feature to differentiate their commercial from their free readers. PDFTypewriter, for example, does the same thing where their Reader gets more features when they use PDFs from their producer. It's a generic feature of PDF that any vendor can use if they wish.

Does adobe offer online signing service API? Or, you can generate something in itext and need to manually sign it in a lifecycle product? Is a non-Adobe reader obligated to check the signature? Can a non-adobe reader just find the form data, let user fill it in, and save it without caring about signature? That seems to be what you suggested before and I'm not sure what facility there is in the PDF that let's you hide the form from the user without an Adobe signature. While PDF may be a standard, and Adobe is not obligated to give away software others can use anywhere, it seems a bit confusing to sell a standard to people only to have them find out they need a private key from a company to fully use the capabilities. ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
