I'm learning Java from the "Head First Java" book. I'm trying to run MyFirstApp which is basically a Hello World type of application. I run Windows XP and I'm jusing Java 5.0. I am able to compile, but when I try to run I get an error:

c:\learn\java>javac MyFirstApp.java

c:\learn\java>java MyFirstApp.class
Exception in thread "main" java.lang.NoClassDefFoundError: MyFirstApp/class

I've read about setting the CLASSPATH variable, but I have tried that as well and I still can't get it to work. Any help here would be greatly appreciated.

Remove the .class part of the command line.
Use just
java MyFirstApp

Sounds like you got over this hurdle. As you explore compiling and running programs, see if THIS (shameless self promotion) helps.
