Summary: Problem in PieChart

Initial Comment:
Having problem in PieChart 

Dear sir,

i am plotting a pie chart with the code given below.



String id = request.getParameter("id");

String name = request.getParameter

("name");



double[] data={0,0,0,0};

String[] labels = new String

[data.length];

labels = 

Util.constructStringArrayFromString("Queued - Not 

Assigned,Assigned - Not Started, Assigned - In Progress, 

Assigned - Wrapup",",");

Paint[] paints= 

{Color.blue,Color.cyan,Color.red,Clor.yellow};



PieChart2DProperties 

pieChart2DProperties = new PieChart2DProperties();

pieChart2DProperties.setPieLabelType

( PieLabelType.VALUE_LABELS );



pieChart2DProperties.setZeroDegreeOffset( 

110 );



LegendProperties legendProperties = 

new LegendProperties();

legendProperties.setPlacement

(LegendAreaProperties.RIGHT );

legendProperties.setNumColumns( 1 );



String heading = null;

if(id.equals("QueuesChart2"))

heading = ""+name+" 

Monitoring - Email";

PieChartDataSet pieChartDataSet = 

new PieChartDataSet( heading, data, labels, paints, 

pieChart2DProperties );



ChartProperties chartProperties = 

new ChartProperties();

chartProperties.setBorderStroke( 

ChartStroke.DEFAULT_CHART_OUTLINE );



PieChart2D pieChart = new PieChart2D

(pieChartDataSet, legendProperties, chartProperties, 

300, 200 );

ServletEncoderHelper.encodeJPEG13

(pieChart, 1.0f, response);



This code draws the image well. but which displaying the 

code it throws an exception. which is also pasted below.
