Programs java and javac are in directory: /home/bilsch/jdk7/bin/
Offending program, Nvr1.java is in directory:

  /home/bilsch/NetBeansProjects/NVRAM/src/

environment variable PATH is:

/usr/lib/lightdm/lightdm:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games

However note that when I run; java Nvr1.class (or simply Nvr1) from my 
home directory the output errors are in javanese, as follows:

bilsch@p4pwj:~/jdk7/bin$ java Nvr1
Exception in thread "main" java.lang.NoClassDefFoundError: Nvr1
Caused by: java.lang.ClassNotFoundException: Nvr1
	at java.net.URLClassLoader$1.run(URLClassLoader.java:217)
	at java.security.AccessController.doPrivileged(Native Method)
	at java.net.URLClassLoader.findClass(URLClassLoader.java:205)
	at java.lang.ClassLoader.loadClass(ClassLoader.java:321)
	at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:294)
	at java.lang.ClassLoader.loadClass(ClassLoader.java:266)
Could not find the main class: Nvr1. Program will exit.
bilsch@p4pwj:~/jdk7/bin$ cd
bilsch@p4pwj:~$ java Nvr1.class
Exception in thread "main" java.lang.NoClassDefFoundError: Nvr1/class
Caused by: java.lang.ClassNotFoundException: Nvr1.class
	at java.net.URLClassLoader$1.run(URLClassLoader.java:217)

	at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:294)
	at java.lang.ClassLoader.loadClass(ClassLoader.java:266)

Could not find the main class: Nvr1.class. Program will exit.

Therefore the command line is hooked up with the java directory - 
regardless of the PATH.

When I change working directory to /home/bilsch/jdk7/bin/ and type in 
the path and filename for the offending file I get the following output:

bilsch@p4pwj:~/jdk7/bin$ javac /NetBeansProjects/NVRAM/src/Nvr1

The program 'javac' can be found in the following packages:
  * openjdk-6-jdk
  * ecj
  * gcj-4.4-jdk
  * gcj-4.6-jdk
  * gcj-4.5-jdk
  * openjdk-7-jdk
Try: sudo apt-get install <selected package>
bilsch@p4pwj:~/jdk7/bin$
bilsch@p4pwj:~/jdk7/bin$

Ubuntu can't find javac even though I ran it from the directory where 
javac resides.  It can't find it from the home directory either.

THE SHORT ANSWER IS I CAN'T COMPILE OR RUN JAVA FROM MY LINUX COMMAND 
LINE.  I can't answer your question of what the output is when running 
command line.  Also I have no idea why Linux won't do it. I'LL HAVE TO 
WORK ON THAT.

I have to figure how to run from command line in linux.  If I could run 
using Windows command line and it worked that would be inconclusive ie. 
taking Linux out of the equation.  If I could run it in Windows command 
line tonight and it worked OK that wouldn't mean it would still work 4 
days from now?

This could be a Linux glitch rather than Java.

Thanks for listening.  Bill S.
