Hi Frank

That would be barcode4J-fop-ext-0.20.5-complete.jar if you're using FOP
0.20.5. You mentioned that JAR earlier so you probably have it around
somewhere already. But apparently it doesn't seem to be picked up. The
errors you get are a clear indication that the barcode extension is not
available in the classpath somehow. "No handler defined for..." means
that a plug-in for a particular namespace is not available. Now, I guess,
you'll have to look into how Cocoon builds up its classpath.
