Answer 1

I guess you have your imports correct and added the library somehow to your project. Then this sounds like a dependency problem.

I would suggest using Maven as a basic tool for dependency management. It's easy to use and helps you with all the hustle you come across. I don't know what IDE you're using. But if it's Eclipse, just add a pom.xml to you project base, convert your project to a Maven Project (right-clicking -> convert -> Maven) and add the jFreeChart dependency. Maven will download the depencies and everything is done :)
