Are you talking about a web application?

Of course, as explained in the book, you can write a PDF
to any OutputStream. For the small standalone examples,
I use FileOutputStreams, because it's easy to run the
sample code without having to install a server.

Chapter 17 is titled "iText in web applications", and it
explains how to use iText to create PDF on the fly that
can be opened in a browser. On p537 in that chapter, you'll
read: Or, if you want the PDF to be saved, rather than to
be viewed in the browser, you can force the browser to open
a Save As dialog box like this:
    " attachment; filename=\"my.pdf\"");

Of course, you'll need to read the complete chapter to
understand how it all fits together.
