Apache FOP 1.1 QRCodes with zxing
apache-fop, barcode4j, java, qr-code, zxing
Solution
You're using xmlns:qr="http://hobbut.ru/fop/qr-code/" which has nothing to do with Barcode4J. Seems like you planned to use some other FOP plug-in than Barcode4J but you ultimately placed Barcode4J in the classpath instead of the right plug-in. BTW, Barcode4J has an integration of ZXing for QR Code production in the HEAD branch of its CVS repository.
Problem
OK I am having an issue producing QR Codes in FOP 1.1 using barcode4j-2.1 and zxing-0.1.2. I currently have a FOP 1.0 implementation working correctly, by adding `<prefer-renderer>true</prefer-renderer>` to the fop configuration file. barcode4j barcodes are working regardless if prefer renderer is set or not, fixed in barcode4j-2.1. I have all necessary dependancies: - fop-zxing-0.1.2-jar-with-dependencies.jar - barcode4j-fop-ext-complete.jar - saxon9he.jar - using for xslt 2.0 ... here is the barcode snippet: ``` <fo:block> <fo:instream-foreign-object> <qr:qr-code xmlns:qr="http://hobbut.ru/fop/qr-code/" width="5cm" message="TEST DATA" correction="m" encoding="UTF-8"> </qr:qr-code> </fo:instream-foreign-object> </fo:block> ``` When trying to convert prefer-renderer seems to have no effect, I am receiving the error: ``` SEVERE: Image not available. URI: (instream-object). Reason: org.apache.xmlgraphics.image.loader.ImageException: The file format is not supported. No ImagePreloader found for null (No context info available) org.apache.xmlgraphics.image.loader.ImageException: The file format is not supported.
