JRXmlLoader.load: Could not resolve type id 'chart'

[Scott J]

I'm using JRXmlLoader to load the sample report Flower.jrxml supplied by JR and it fails to recognize the chart element.

JasperDesign design = JRXmlLoader.load("Flower.jrxml");

The net.sf.jasperreports.jackson.util.JacksonRuntimeException error says "Could not resolve type id 'chart' as a subtype of `net.sf.jasperreports.engine.JRChild`"

 

The JR library should know that 'chart' is JRChart, which does extend JRElement which extends JRChild. Do I need to manually add "chart" as a known type id?

 

I searched and searched sample code, this forum, and developer resources for this issue and found nothing. Searched for enabling charts in Jasper reports, found nothing.

 

Help please?

I also got the same error when using JasperCompileManager.compileReportToFile

Hi, you need to ensure jasperreports-charts-7.x.jar and jfreechart-1.5.4.jar are in your classpath
