I guess you did set them in your property file.

ant does not know anything unless you tell it.

1) In my build.properties (read first)
jdk13.bin=${tools.home}/jdk1.3.1_13/bin
jdk14.bin=${tools.home}/j2sdk1.4.2_08/bin/

2) In my master properties file (read last), set default
javac.location=${jdk13.bin}

3) In my prj.properties, if I need to use 1.4
javac.location=${jdk14.bin}

4) in my javac task
executable="${javac.location}/javac.exe"

Adjust the values according to your own environment.

Good luck!
