Not that I can tell. I've found that if I set CLASSPATH, it overrides
(rather than augments) the default CLASSPATH, and I don't know enough about
the default CLASSPATH to correctly duplicate the important bits in a custom
CLASSPATH.

As mentioned, I don't have a CLASSPATH to unset.. But I've tried renaming
the possibly-conflicting jars in $java_bin\lib\ext (by changing their
extensions to things like jarx), to no avail.
Any other suggestions?
Continued thanks,

I found this in the Ant FAQ :<br>
<br>
I installed Ant 1.6.x and now get <code>java.lang.InstantiationException:
org.apache.tools.ant.Main</code>
<p> The cause of this is that there is an old version of ant somewhere
in the class path or configuration. </p>
<p> A version of this problem may be seen on some linux systems. Some
linux systems (Fedora Core 2 for example), comes with a version of ant
pre-installed. There is a configuration file called <code>/etc/ant.conf</code>
which if present, the ant shell script will 'dot' include. On Fedora
Core 2, the /etc/ant.conf file resets the <code>ANT_HOME</code>
environment variable to <code>/usr/share/ant</code>. This causes the
problem that an old version of ant (1.5.x in this cause) will be used
with a new version of the ant script file. </p>
<p> One can check if this is the case by doing <code>ant --noconfig
-version</code>.<br>
