I am trying to generate a Barcode4j QR Code from a Jasper report through the Jasper report plugin.
I am getting an error “java.lang.NoClassDefFoundError: com/google/zxing/WriterException”, issued this error on [https://github.com/Servoy/servoy\_jasperreports/issues](https://github.com/Servoy/servoy_jasperreports/issues) one year ago, no response until now.
No problem when report runs from JasperSoft Studio, I guess the needed library is not present in the Jasper report plugin.
Any help is very appreciated!

Hi
We are producing QR-Codes with the jasperreports-6.4.1.jar plugin and in the plugins\servoy\_jasperreports\ directory there is a file barcode4j-2.1.jar. Maybe this one is missing?

Hi,
This is how we solve it:
1. added javase-3.3.1.jar and core-3.3.1,jar plugins into plugins/servoy\_jasperreports folder
2. added the following line of code in servoy\_jasperreports.jar.jnlp file ( you can find it in the plugins folder)
3. added the following line of code in the plugins.properties file
servoy\_jasperreports/core-3.3.1.jar=1637773803110:545396
servoy\_jasperreports/javase-3.3.1.jar=1637773812071:41688
4. Restarted tomcat and the application server.
And yes, we need also the barcode4j-2.1.jar file as murmi said.
Hope it helps

Hi,
I placed the zxing jar file in the servoy\_jasperreports directory and added the following lines to the servoy\_jasperreports.jar.jnlp :
It’s a pity that the zxing is not included the the Barcode Jasperreports build.
