I have a small applet which I can run in eclipse (3.0) as a java applet
just fine. I wanted to see if I could create my own ant build file (shown
below), but it stops at the line:
<javac srcdir="${src}" destdir="${bin}" />
and the console window contains:
Buildfile: C:\Program Files\eclipse\workspace\test\build.xml
init:
compile:
[javac] Compiling 1 source file to
C:\Program Files\eclipse\workspace\test\bin
BUILD FAILED: C:\Program Files\eclipse\workspace\test\build.xml:16:
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
Total time: 750 milliseconds
Can anyone help me figure out what I've done wrong?
Thanks,
Bobby Berns

Thanks Darin. Adding the -vm to the eclipse startup did it. I HAD set
JAVA_HOME to a jdk in my system environments variables, but that somehow
didn't do it.
I also found that If I set fork to yes in the javac, thus allowing ref to
external jdk handled it also.
