JasperReports Integration and QR code throws exception #8

#1

I am using the Integration Kit 2.4.0. with a Jasper Report build in 6.10.0.
When I use the QR Code then it runs fine in the preview but not in APEX (19.1)
Is there something I need to add or install?

The error is
java.lang.NoClassDefFoundError: org/apache/xml/serializer/TreeWalker

Complete Browser error

HTTP Status 500 – Internal Server Error

Hi, did you manage to solve your problem?

I copied the serializer-2.7.1.jar file into the /var/lib/tomcat/webapps/JasperReportsIntegration/WEB-INF/lib folder and the error message no longer appears, but neither does the QR Code.

Hi,
After some research I managed to successfully print my precious QR Code!

To achieve this I did the following steps:
1 - Download and copy de file serializer-2.7.1.jar to the folder:
/var/lib/tomcat/webapps/JasperReportsIntegration/WEB-INF/lib on the server.

2 - Edit the file /var/lib/tomcat/webapps/JasperReportsIntegration/WEB-INF/classes/jasperreports.properties and added the line:
net.sf.jasperreports.components.barcode4j.image.producer=image

3 - DONE, the QR Code appears in the report!

I hope this can help someone in the future.
