Thanks for the response. Once I figured out how to create the document
in memory, I passed it from subroutine to subroutine.
I appreciate the help.

Then you could also create a PdfCopy which is very similar to a
PdfWriter. Whether an additional file is created or not depends upon
the output stream you select. If you use a new FileOutputStream then
you will need to specify a destination for the physical file. If
instead you use a BinaryOutputStream (let's call it baos) then your
output will only reside in memory. You can then create a PDF from this
BinaryOutputStream with new PdfReader(baos.toByteArray()). Your PDF
will exist in memory and can be concatenated with other PDFs.
In short, create a PdfCopy of your file from the database using a
BinaryOutputStream. Then append the additional PDFs to this PdfCopy:
PdfReader reader = other PDF to append.
PdfCopy copy = new PdfCopy(document, baos);
for (int page = 0; page < reader.getNumberOfPages(); ) {
copy.addPage(copy.getImportedPage(reader, ++page));
}
Keep the same copy and repeat above until all PDFs have been appended.
Then close your baos and either send it back to the database or create a
physical file.
Thanks.
