Hi Friend,

Download jfreechart.jar and jcommon.jar and put it into the lib folder of jdk and if you want to use jfreechart with jsp or servlet then put the jar files into the lib folder of apache-tomcat.

Set these jar file in your class path through the following path:

My Computer<<properties<<Advanced<<Environment Variables.

For more information,visit the following link:

Thanks
