Eclipse下用ANT没有找到JAVAC

[Eniak]

我在Eclipse下用Ant, 编译器告诉我说Java的东西没有设置对，帮我看看应该怎么设置吗？
我觉得我的CLASSPATH下面没有设置，应该怎么设置，另外，我在电脑上没有找到com.sun.tools.jar

BUILD FAILED
C:\Documents and Settings\n7063318\workspace\simple\build.xml:25: 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\jre1.6.0_01"

环境变量下，我是这么设置的
JAVA_HOME = C:\Program Files\Java\jre1.6.0_01
PATH = C:\Program Files\StormII\Codec;C:\Program Files\StormII;%ANT_HOME%\bin;%JAVA_HOME%\bin
CLASSPATH = %JAVA_HOME%\lib\dt.jar;%JAVA_HOME%\lib\tools.jar

java_home must point to the jdk, but not jre.

JAVA_HOME
设置尽量不要带空格，汉字
