code :

<html>
<body>
String view = (String)request.getAttribute("option");
      if (view.equalsIgnoreCase("chart")) {

            int startIndex = 0;
            Vector vector = (Vector)session.getAttribute("defects");
            Iterator itr = vector.listIterator();
            int count = vector.size();
            int cd = 0;
            int od = 0;
            int fd = 0;
            int sd = 0;
            int ke = 0;
            DefectDetails dd = null;
            while (itr.hasNext()) {
                  dd = (DefectDetails)itr.next();
                  String status = (String)dd.getTechMStatus();
                  if(status.equalsIgnoreCase("closed")) {
                        cd = cd++;
                  }
                  if(status.equalsIgnoreCase("open")) {
                        od = od++;
                  }
                  if(status.equalsIgnoreCase("fixed")) {
                        fd = fd++;
                  }
                  if(status.equalsIgnoreCase("known error")) {
                        ke = ke++;
                  }
                  if(status.equalsIgnoreCase("solving")) {
                        sd = sd++;
                  }
            }
            final DefaultPieDataset data = new DefaultPieDataset();
        data.setValue("Closed", new Double(cd));
        data.setValue("Open", new Double(od));
        data.setValue("Fixed", new Double(fd));
        data.setValue("Known Errors", new Double(ke));
        data.setValue("Solving", new Double(sd));

        JFreeChart chart = ChartFactory.createPieChart
        ("Pie Chart ", data, true, true, false);

        try {
            final ChartRenderingInfo info = new
          ChartRenderingInfo(new StandardEntityCollection());
            File file1 = new File("C:\\Program Files\\Apache Software Foundation\\Tomcat 5.5\\webapps\\piechart.png");
            ChartUtilities.saveChartAsPNG(file1, chart, 600, 400, info);
        } catch (Exception e) {
            out.println(e);
        }
%>

melchkishore is right, it's likely that now you have 2 jcommon.jar files in your path, and one of them is not the version that goes with your chart code.  Or that the jcommon.jar that you put in your classpath does not go with the version of jfreechart you are trying to run.

You can also see that the signature of the method that gives the exception is different from the one listed in your IDE, so that's the clue that there's a version problem.  You didn't write the call to RectangleInsets, it is within the Jfreechart classes somewhere, and it's calling a different method signature.

You don't put server file paths into html.  You put the url for the image, which in this case would be "/piechart.png".

The way EE works, you award points for the help you got, and if you have a new question, you open a new question.

no, im still facing the problem

the code is working fine with a small problem. that is the code is working on the server end. but not at the client side. means the jsp is not getting the updated image from the server every time when the request maid for the jsp. but when the new browser is opened and make a request to the jsp then the updated image is relecting.

im unable to understand what might be the problem in this ?
can you plz provide the solution for this one.
