Ant ne fonctionne pas: impossible de trouver un compilateur javac

Je suis en train d'exécuter du Java EE exemples. Ant suggère: Perhaps JAVA_HOME does not point to the JDK. It is currently set to "C:\Program Files\Java\jre7

Mon JAVA_HOME variable est: C:\Program Files\Java\jdk1.7.0_03 quand je regarde mon windows 7 variables

Cependant, mon chemin est (notez le jdk1.6.0_26):

%M2_HOME%\bin;%ANT_HOME%\bin;%JAVA_HOME%\bin;%SystemRoot%\system32;%SystemRoot%;
%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\;
C:\Program Files\Microsoft Application Virtualization Client;%M2%;
C:\Program Files\QuickTime\QTSystem\;C:\Program Files\TortoiseSVN\bin;
%GLASSFISH%;%GLASSFISH_PARENT%;

PATH=C:\Maven\apache-maven-2.2.1\bin;C:\Ant\apache-ant-1.8.2\bin;**C:\Program File
s\Java\jdk1.6.0_26\bin;**C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C
:\Windows\System32\WindowsPowerShell\v1.0\;C:\Program Files\Microsoft Applicatio
n Virtualization Client;C:\Maven\apache-maven-2.2.1\bin;C:\Program Files\QuickTi
me\QTSystem\;C:\Program Files\TortoiseSVN\bin;C:\glassfish3\glassfish\bin;C:\gla
ssfish3\bin;C:\Sun\jwsdp-2.0\jwsdp-shared\bin

Dois-je faire quelque chose de spécial pour obtenir windows pour enregistrer mon chemin?
