Re: Problems with Apache FOP and Barcode4j

[Jeremias Maerki]

Thanks for the extensive additional data. I might have the problem now.

This indicates that the Barcode4J FOP extension is not correctly set up
with FOP. Please note that FOP 0.95 needs a different extension than FOP
0.20.5 because the extension APIs have changed. Please put
"barcode4j-fop-ext-complete.jar" (from Barcode4J 2.0) into your
classpath (and remove the old JAR). The above error message should then
go away and the barcodes should appear.

But that doesn't really explain why you got the "mismatch" error. Maybe
we need to take this one step at a time.
