loading data into a pdf [Advanced Techniques]

From: emerys on 16 Apr 2008 15:15

I was using CF7 to query data and load it into pdf file using the XPAAJ java
library from Ben Forte's blog. It was simple, and it worked very well. Then
along came CF8 and LiveCycle ES. XPAAJ was free, but LiveCycle ES is not free.
LC ES does much more than loading data into a pdf and costs quite a bit, but is
probably worth the money. Because a small part of LC ES does the same thing
that XPAAJ did, the CF8 upgrade knocks out XJAAP almost completely. (I got it
back by stopping the CF8 application service, starting the CF7 application
service, then restarting the CF8 - I don't want to run like this for very
long).
I may eventually get into LiveCycle, but for now, does anyone know of
something like XPAAJ that can load data directly into a pdf, or a Form Data
Format (FDF) file?
Thanks Scott

If by PDF 'data' you mean XMP metadata, then yes: CF8 ships with a version of
the iText Java library that includes classes for reading and writing XMP in
PDF. CF8's CFPDF tag uses iText under the hood but doesn't yet allow you to use
all of its functionality via CFPDF, so you can just call the Java classes
directly in order to access iText's XMP functionality.

Examples of reading and writing XMP are given here:

Check Ray Camden's pdfUtils CFC on riaForge: it contains a new readXMP()
method. writeXMP() is coming - the code is included in the thread above anyhow.
Hope this helps.

Thank you Ed. It looks like CFPDF is doing everything I need.
