Could not create chart customizer instance. Works in iReport however

[ruud.vanheugten]

For a jasperreport that I've created in iReport I created a ChartCustomizer as follows:

public class BarChartBlackOutlineCustomizer extends JRAbstractChartCustomizer {    @Override    public void customize(JFreeChart jFreeChart, JRChart jasperChart) {        if(jasperChart.getChartType() == JRChart.CHART_TYPE_BAR) {            //Chart is a bar chart            BarRenderer renderer = (BarRenderer) jFreeChart.getCategoryPlot().getRenderer();            //Removes gray line around the bar            renderer.setDrawBarOutline(true);            renderer.setBaseOutlinePaint(Color.BLACK);            renderer.setBaseOutlineStroke(new BasicStroke(1f));        }    }}[/code]

In iReport I've added the jar to the classpath and added it to my chart as customizer. When I generate a preview in iReport no errors show up and the customisation of the chart works as expected. I'm also able to compile the report to a .jasper file.

In my Jetty-webserver I want to use the .jasper file to generate a Pdf file from a Xml file. However when I try to generate the Pdf file I get the following error

So I guess there is a minor configuration issue but I can't seem to solve it. I tried adding the .jar file to my project, tried adding the .jar file to the web-inf folder and also tried adding the .jar file to the jetty-etc.zip file in the same folder as the .jasper. Help would be really appreciated.
