PieChart Labels in a Servlet

[TheHaas]

I'm running 0.9.17. I have the following in my code:

Code: Select all

PiePlot plot = (PiePlot) piechart.getPlot();
plot.setLabelGenerator( new StandardPieItemLabelGenerator("{0} - {2}"));

The above works fine when I render the chart in a ChartFrame, but if I do it in a servlet, I get an exception:

Code: Select all

javax.servlet.ServletException: org.jfree.chart.labels.StandardPieItemLabelGenerator.(Ljava/lang/String;)V

Anyone have any ideas?

Any chance that you have more than one jfreechart jar file on the classpath?
