Hi Srividhya,
Actually the coding which you have mentioned in your example calls the chart directly which gives out error when i call them in jetspeed portal.So we made small changes in the coding so that all the chart related files(JSP files, chartlib,Fusion chart include files) are placed in a separate folder which is placed outside WEB-INF folder and when we call them it works perfectly.
This works perfectly fine Srividhya.
Any queries plz write to me
