How to properly use Custom Visualization Component

[shravani.9418]

Hi,
I'm new to Jasper reports and it is a great tool to build real time reports within my Springboot application.
I have tried Bar charts and also using tables with custom data sources.
However, I have a usecase where i have to use the Custom Visualization Component (radial dial) in my report.
The process i followed is designed the report in studio and copied JRXML to compile within my java app.

net.sf.jasperreports.engine.JRRuntimeException: Unknown entity http://www.jaspersoft.com/cvcomponent/component.xsd, not loading.

I get the following error and also weirdly 

<cvc:customvisualization                        xmlns:cvc="http://www.jaspersoft.com/cvcomponent"                        xsi:schemaLocation="http://www.jaspersoft.com/cvcomponent http://www.jaspersoft.com/cvcomponent/component.xsd"

is not reconized by my intellij.

Please help.

Thanks and Regards,
Shiva

You need to include a jasperreports-custom-visualization jar in your application.  If you use Maven see https://search.maven.org/artifact/net.sf.jasperreports/jasperreports-custom-visualization

Hello shravani.9418,

Did you manage to make your custom visualization component working in your spring boot application ?

On my side, I manage to compile my jrxml files that includes my custom visualization component but the pdf that is created is empty, any idea if I am missing an obvious configuration ?

Thanks
