Hi Simon,

Here's the code used by the <cactus> task to find the tools.jar
file:

   protected final File getToolsJar()
       throws FileNotFoundException
   {
       String javaHome = System.getProperty("java.home");
       // TODO: Fix this as it fails on Max OSX (which doesn't have
a

       // tools.jar file).
       File toolsJar = new File(javaHome + "/../lib/tools.jar");
       if (!toolsJar.isFile())
       {
           throw new
FileNotFoundException(toolsJar.getAbsolutePath());

       }
       return toolsJar;
   }
So it means it cannot find it in [javahome]/../lib/tools.jar

Do you know where it is for you (i.e. what directory)?
Hmm, does this mean that this works for you in Eclipse?

Obviously this code is quite broken, and was just one of those quick
and

dirty hacks none of us ever produces ourselves ;-) I think that
tools.jar

(or whatever classpath entry contains the Java compiler) should
normally

always be on the Ant classpath. So some type of lookup to find the
resource
that contains the compiler should do the trick. I'll need to look into
the

<javac> etc, to see how the Ant folks get the compiler on the
classpath of

a
forked VM.


Ok cool. I agree. One of the problem with eclipse when you use Ant from
within Eclipse is that Eclipse automatically creates a JRE setup (and
not a JDK one) and thus the tools.jar is missing. But I agree that once
the JVM is correctly setup, we should be transparent. What we could do
maybe is simply try to load some class from tools.jar to see if it's on
the cp somewhere?
That's what I've been thinking, but it won't work for people using JDKs 
other than Suns. But it'd definitely be better than the current approach.

The solution must be somewhere in the Ant code base, I hope :-/
