Ant can't find Javac. No matter what I do it always claims JAVA_HOME is “C:\Program Files\Java\jre6”

RussianQuestion
...and that's wrong.
Here's the error I get:
BUILD FAILED C:_TraderPlatform\Clients\Open\Open\Java\Applets\PPDataTransporter\nbproject\build-impl.xml:338: The following error occurred while executing this line: C:_TraderPlatform\Clients\Open\Open\Java\Applets\PPDataTransporter\nbproject\build-impl.xml:158: Unable to find a javac compiler; com.sun.tools.javac.Main is not on the classpath. Perhaps JAVA_HOME does not point to the JDK. It is currently set to "C:\Program Files\Java\jre6"
I've set an environment variable called JAVA_Home to point to: "C:\Program Files\Java\jdk1.6.0_12"
Javac.exe is definitely in C:\Program Files\Java\jdk1.6.0_12\bin
I've got %JAVA_HOME%\Bin in my PATH variable.
I've mucked around with the various 'JavaHome' settings under HKLM\SOFTWARE\JavaSoft and I'm now utterly stuck.
All I wanted to do was build a Java applet from the command line using the build.xml that netbeans had knocked up for the project.
Any ideas anybody?
Solution
Well ANT now works.
What did I do?
I removed it from c:\program files and 'reinstalled' it into "c:\ant"
Seems like it doesn't like non 8.3 filenames or directories.
Funnily enough I did this only because I misread the part of the manual that suggested ANT shouldn't be in non 8.3 style locations on 95/98/ME. I didn't spot the OS reference and gave it a go. I'm running Vista.
Oh well...
Thanks for your help guys.
OTHER TIPS
In eclipse set the installed JRE setting to the JDK - in the project (project properties -> Java Build Path-> Libraries), or global default in preferences (Java->Installed JREs). The eclispe setting is stronger than the system variable.
Just include tools.jar on the ant classpath, wherever it is installed.
You need to check that the variable name is JAVA_HOME all uppercase. Also, run path from the command line and ensure that the path statement has the correct value for JAVA_HOME.
What build process are you running? Is one of the build scripts setting JAVA_HOME?
OK, guys, for Windows 7 it needs the JAVA_HOME as a Windows Environmental Variable, I've also added C:\Program Files\Java\jdk1.7.0_03\ and C:\Program Files\Java\jdk1.7.0_03\bin to PATH, restarted Eclipse, now it works.... Well I have other problems though :D
