umme

Hey! Lucian, Thanx for your answer and cooperation. I've solved my problem. It was about ireport plugin for netbeans. After I reinstall my IDE and set ireport pluging environment again, I found my programs running without error including piechart. regards Umme.

Thanx again. NO, I can't see my chart in jasper viewer. The portion of where the pie chart to be shown is blank. I can upload that pdf file but the chartcontent is not there, only the tabular report part is containing there. I've test it only for pie chart not include the tabular part. And this time no pdf file has created showing no errors. If I use :[ ChartFrame frame = new ChartFrame("EmployeeChart", chart); frame.pack(); frame.setVisible(true); ]instead of createing image.. then I found my desired piechirt as output. pls help me.
