Thanks, Diane! You helped lead me to figuring it out for myself.

I do have to migrate toward property files, but this is the basic recipe I
was looking for:
1) Make sure the location of your Javac compiler classes are in the
classpath in which you invoke Ant! Somebody went through the pain of
creating painless batch/shell commands for Ant in Ant's bin directory, but I
ignored them for my own nefarious reasons.
i.e.: C:/jdk1.3/lib/tools.jar
2) The Ant 1.3 <javac> target arguments includeAntRuntime/includeJavaRuntime
provide the magic. For my situation, the default settings are correct,
especially includeJavaRuntime defaulted to "no" which allows me to pick the
Cross-Compilation of my choice.
3) I just have to be sure the correct classes.zip(jdk1.1.8) or
rt.jar(jdk1.2+) are a used for the <javac> target's bootclasspath that I
need.
4) And easy to forget, 'extdirs' needs to point to the 'extdirs' that belong
to the intended cross set of extentions.
Javac target example:
<javac srcdir="${src}" destdir="${classes}"
includes="**/*.java"
excludes="**/examples/**,**/test/**"
bootclasspath="C:/jdk1.1.8/lib/classes.zip"
extdirs=""
classpathref="project.class.path"
optimize="on" debug="on"
target="1.1" deprecation="off"
>
</javac>
Does that compute? Or have I missed something?
Kind Regards,
Greg Kedge
