| Very Bad use of Ant... | Very Bad use of Ant... 2006-08-28 - By Dan McFadyen
No idea, but..
Straight from the command prompt on my other screen:
....
[java]
[java] The ' characters around the executable and arguments are
[java] not part of the command.
[java] Setting environment variable: JAVA_HOME=C:\jdk1.5.0_07
[java] Buildfile: build.xml
....
....
[java] com.sun.tools.javac.Main is not on the classpath.
[java] Perhaps JAVA_HOME does not point to the JDK
....
And that's as far as I have gotten...

Could it be it's finding the JRE versus the JDK (or SDK)...
