Windows 7: Environment variables to point to the Java compiler

Environment variables to point to the Java compiler

Hi everyone

I have recently installed the Java Development Kit 6 in my Windows 7 Ultimate 32 bit installation but not been able to set the path to the javac compiler in the Environment Variables. What I have done so far is:
  1. Opened the Environment Variables dialog obx
  2. Created a new PATH to C:\Program Files\Java\jdk1.6.0_20\bin under User Variables
  3. Added C:\Program Files\Java\jdk1.6.0_20\bin to the right end of the series of directories called 'Path' under System Variables
The instructions on this in the Oracle website seems to be written for Windows XP and apparently different setup is required for Windows 7. All I want to do is every time I launch Command Prompt, the Prompt knows where javac.exe is so it can execute it without my typing the path to the compiler.

I would like to have as much as avice/instructions as possible because it has been nagging me for quite some time and irresolvable.

Thank you in advance,

Derek

You don't want to add a new user variable for PATH.

You just want to add your Java JDK bin library TO THE END OF THE EXISTING PATH VARIABLE that currently exists in the system area of the environment variables, as you've done (presumably you've correctly prefixed this new appendage with a ";" to separate it from the prior item in the existing PATH list). That really should work.

Yes, I also tried adding the path to the JDK directory to the right end of the system variable Path with no luck. In that incident I did not include PATH to the users variable. Command Prompt returned:

'javac' is not recognized as an internal or external command,
operable program or batch file.

Any more advice would be appreciated.
