Jasper Charts Themes Exception

[thangalin]

I have looked at these pages:
    http://jasperforge.org/public.php

    http://sourceforge.net/projects/jasperreports/files/1.jasperreports/
 

And inside:
     jasperreports-3.7.0-project.zip

But I cannot find the source to the Charts extensions library (jasperreports-chart-themes-3.6.2.jar).

I have encountered the following error:

Caused by: java.lang.NoSuchMethodError: net.sf.jasperreports.charts.JRLinePlot.getCategoryAxisVerticalTickLabels()Ljava/lang/Boolean;
    at net.sf.jasperreports.chartthemes.simple.SimpleChartTheme.createXyLineChart(SimpleChartTheme.java:1494)
    at net.sf.jasperreports.chartthemes.simple.SimpleChartTheme.createChart(SimpleChartTheme.java:399)
    at net.sf.jasperreports.engine.fill.JRFillChart.evaluateChart(JRFillChart.java:1287)

And cannot resolve it.

Am using:

jasperreports-03_07_00.jar

jasperreports-chart-themes-03_06_02.jar

jasperreports-fonts-03_07_00.jar

jcommon-01_00_16.jar

jfreechart-01_00_13.jar

iText-02_01_06.jar

castor-01_02_00.jar

I am curious as to why the SimpleChartTheme is being referenced when I am using a custom theme. Inheritance?

Thanks!

The source of the chart themes can be found under demo/samples/chartthemes/src.  The error is probably caused by an unsupported JFreeChart version, try to use the one shipped with JasperReports.

Hi.

I have updated the libraries to the following:

jfreechart-01_00_12.jar

jcommon-01_00_16.jar

jasperreports-fonts-03_07_00.jar

jasperreports-chart-themes-03_06_02.jar

jasperreports-03_07_00.jar

iText-02_01_06.jar

castor-01_02_00.jar

Same error:

Caused by: java.lang.NoSuchMethodError: net.sf.jasperreports.charts.JRLinePlot.getCategoryAxisVerticalTickLabels()Ljava/lang/Boolean;
    at net.sf.jasperreports.chartthemes.simple.SimpleChartTheme.createXyLineChart(SimpleChartTheme.java:1494)

I think it happens because the instance of JRLinePlot created using the factory does not implement getCategoryAxisVerticalTickLabels.

Further, I have removed all instances of jfreechart-01_00_13.jar from the system.

Strange. If I figure it out, I'll post a reply. More ideas are appreciated.

My bad, I misread the error.

The probable cause is an older (than 3.6.2) JR jar somewhere on your classpath.  Could you check that?
