Hi Friends,

//=================================================
An error occurred at line: 33 in the jsp file: /index.jsp
The type org.jfree.util.PublicCloneable cannot be resolved. It is indirectly referenced from required .class files
30: final ValueAxis valueAxis = new NumberAxis("Run");
31: renderer = new BarRenderer();
32:
33: plot = new CategoryPlot(dataset, categoryAxis, valueAxis,
34: renderer);
35: plot.setOrientation(PlotOrientation.VERTICAL);
36: chart = new JFreeChart("Srore Bord", JFreeChart.DEFAULT_TITLE_FONT,
//================================================== =


Help me friends, Thanks a lot in advance.
