Mounting filesystems and such

Hi all.

I'm new to Java, new to NetBeans, and have been assigned the Java 
Programming course at my JC this semester. I'm excited about teaching 
Java - have been looking for an excuse to learn it for a while (in my 
real life, we don't use java at all for performance reasons - I'm a 
programmer for Agilent Technologies).

I'm working my way through Thinking in Java, and have loaded Eckel's 
code onto my machine for experimentation. I've mounted a subdir called 
"code" as a filesystem, and want to be able to open each chapter subdir 
and compile/run the code from there. However, I think I have a path 
problem that is causing the following error.

I'm trying to run some code ~/code/c03/VowelsAndConsonants.java, but 
when I compile, it gives me the error

Exception in thread "main" java.lang.NoClassDefFoundError: 
c03/VowelsAndConsonants (wrong name: VowelsAndConsonants)

I suspect that it's not finding the right directory when parsing the 
input file, but I can't figure out how to fix it.

Any suggestions for solving this problem?

Are there any other resources that I can use in my class next semester?

Thanks!
