Thanks. I suppose I'll use a batch file to temporarily set CLASSPATH. It's ugly, but workable.

Subject:  Re: taskdef-classpath fails to add jars to classpath

Hello,
the fact that the class

org/apache/avalon/framework/logger/Logger is not found might indicate that this class
is loaded directly or undirectly by another class, which is using your startup classloader.
this is documented under http://ant.apache.org/faq.html#delegating-classloader
This kind of problem happens often with classes which are loaded by factories, such as JDBC
or JNDI drivers.
There is nothing much you can do about this.
[except that sometimes I dream of classloaders being made aware of their children, maybe with
a stack or probably
even a graph structure ]
Cheers,
Antoine
