I figured the classpath was correct given that it compiles...

Well, the problem is that the class is not "BasicFrame"
but "JFCBook.Chapter2.BasicFrame"
If you remove the package statement or if you use the full class name
when trying to run the class you will be fine.
The java command needs the full class name since ther is no "import"
for the class name used to run from the command line - import is only
a compile-time typing shortcut and not a run-time item. Classes that
are not in a specific package are in the "outer" package - as in nothing
to prefix the name.
