I create a project in Eclipse using FOP 2.2. Barcodes and QR codes are required in the PDF files created by the project. Barcode4j is able to create barcodes, however, qr codes are created only if there is a zxing core, which, based on this, Apache FOP 1.1 QRCodes with zxing needs to be downloaded from CVS Repository. I did everything that is said in this post, but when I try to create a qr code
<fo:block>
<fo:instream-foreign-object>
<barcode:barcode xmlns:barcode="http://barcode4j.krysalis.org/ns" message="test">
<barcode:qr/>
</barcode:barcode>
</fo:instream-foreign-object>
</fo:block>
I get an error.

I would like to understand the reason for this error, and also to find out whether there are alternative ways to generate barcodes and qr codes using FOP.
