Re: Using krysalis with Tomcat to output PDF barcodes

Sorry to ask again for your help, maybe I'm not so far to make it work...

My initial problem was because I'm under unix with no Server X available.
I've tried several solutions ( -Djava.awt.headless=true, Xvfb (X virtual
frame buffer) and the PJA library wich replace AWT). In each cases, I've got
the same results: works in command-line but not in Tomcat servlet. However,
I noticed that the previous solutions enable the krysalis sample servlet to
output images (PNG, JPEG) whereas it didn't work without a solution for the
serverX. So i think the server X isn't the actual problem for my
krysalis-fop-extension servlet.

The result I obtain now invoking my fop servlet with a .fo input file (with
barcode instructions) is a PDF file with some text but without barcode.
There's no error messages except the following in the logs/catalina.out:

Apache Tomcat/4.0
Starting service Tomcat-Apache
Apache Tomcat/4.0
[ERROR]: Logger not set
[INFO]: building formatting object tree

[INFO]: [1]

Hope it's a good clue for you, as for me, i don't know what's wrong and what
to do....
