[Bluej-discuss] JFreeChart with BlueJ?

[rhg5 at kent.ac.uk]

Michael,
The JFreeChart library files were extracted from a downloaded zip file, and consist of directories, subdirectories, and .java files.  I'm confused about where the jars fit in with this.  From the BlueJ Manual I read:

"One small thing to look out for: if the classes are in a jar file, select the jar file itself as the library. If your classes are in a named package directory structure (for example in a directory named "simpleIO"), choose the directory that contains simpleIO (not the simpleIO directory itself) as the library!"

from which I thought the ones I am looking at were in package directories.  I've used the BlueJ Preferences to point at all the relevant directories, at least that what I've tried to do, but I still can't make it work.
