Hello, Dear members.
I have a question regarding how to generate the pdf document, insert a
couple of text fields, and then fill in those text fields from a database at
the same time.
Here is a good example (
http://itextpdf.com/examples/index.php?page=example&id=157) on how to create
and fill in a form.
But I don't want the intermediate file, I just want to create the pdf file,
and fill in the fields in memory, and then send it to the client over Http ,
what's the best way to do it? Basically, I want to get the AcroFields from
the writer, not from the reader.
Thank you for your help.
