Yes, it is possible to use iText to sign a document using trusted 
certificates provided by many different CAs, including Verisign. If you 
don't want to believe me, you may want to believe the American Office of 
Legislative Counsel:

You need at least iText 5.3.3 if you want the examples from the white 
paper to work.
This is clearly described in the afterword of the documentation:

Please read the documentation so that you can save your and our time for 
important questions.
