I am trying to get jFreeChart to work in a Java application using a simple example program from the jFreeChart Developer’s Guide, but get a case of “red squiggles” (compiler errors) on every reference to a jFreeChart object. I have tried adding the directory that contains jcommon-1.0.0.jar and jfreechart-1.0.0.jar to the Project build path (Link additional source to project), but am still having trouble. Any help will be greatly appreciated, but please keep it simple. Thanks again.

John, you don’t want to add the DIRs, you want to add the JARs themselves to your Java Build Path > Libraries tab.
OK, I created a project named jFreeChart and with it selected, I right-clicked and went to Build Path | Add Libraries | User Libraries | New and gave it a name of jFreeChartLib. Then Add Jars and selected jcommon-1.0.0.jar and jfreechart-1.0.0.jar. then open | OK | Finish. At this point, I can see jFreeChartLib in my Package Explorer with the two Jars below it.
Back to the jFreeChart project, create a package named chapter04, and under that a class named First.
Still all the “red squiggles”. What am I doing wrong?
