ChartEntity entity = cme.getEntity();
if (entity != null) {
System.out.println("Mouse clicked: " + entity.toString());
}
else {
System.out.println("Mouse clicked: null entity."+entity);

Try this:
import org.jfree.chart.ChartMouseEvent;
import org.jfree.chart.ChartMouseListener;
import org.jfree.chart.entity.XYItemEntity;
final class ClickedIndexMouseListener implements ChartMouseListener {
#Override
public void chartMouseMoved(ChartMouseEvent event) {
}
#Override
public void chartMouseClicked(ChartMouseEvent event) {
try {
XYItemEntity ce = (XYItemEntity) event.getEntity();
System.out.println("Item " + ce.getItem());
System.out.println("Series " + ce.getSeriesIndex());
System.out.println("X Value " + ce.getDataset().getX(ce.getSeriesIndex(), ce.getItem()));
System.out.println("Y Value " + ce.getDataset().getY(ce.getSeriesIndex(), ce.getItem()));
} catch (Exception e) {}
}
}
