Sounds like a PATH issue...

Maybe you should just use the NXT-G software that comes with the NXT set to get 
him started....

Subject: [Lejos-discussion] Need help setting up NXJ software for NXT

hello -

     I humbly request your assistance.   My son received an NXT for Christmas.  
 I've tried for a month and half now to install the NXJ software on our 
computer and failed.    I've read everything I can find in the online    
support and am still stuck.

    Here's what I've done so far:

    1)Installed the NXJ software
        being new to this...I updated the firmware on the NXT at this point.   
Is this okay???

    2)installed libusb filter driver
    3)setup the variable NXJ_HOME and added it to the system PATH variable, as 
well as, %NXJ_HOME%/bin
    4)Java....
        I'm very confused about java.  I've read some places where I need the 
JAVA SDK,
        and someplace else that I need the JAVA JRE.   I read one place I need 
to add JAVA_HOME to the
        system PATH variable,  and another place that I do not.   I currently 
have jre1.5.0_9 installed

        In either case,   when I attempt to run
        nxjc tune.java
        I get the error message:
        javac is not recognized as an internal or external command, operable 
program or batch file

      I've tried to run this command: ( nxjc tune.java)
      1- with java sdk installed
       2-uninstall java sdk, and install jre
       3-with java_home defined,   and without java_home defined.

       in each scenario - I get the javac not recognized.


       I attempted to register on the lejos.org this afternoon, and got the 
message the page couldn't be displayed.

      My son would really like to use his NXT.   Please, please, please help me 
get the software setup for him.

      thanks,
         Robin
