Hi Costin,
looking at classloader, it seems to imply that it can
be used at to ant's default classloader, to help in defining
tasks/types.

However when I try to do:
<project name="c">
    <mkdir dir="classes"/>
    <javac srcdir="src" destdir="classes"/>
    <classloader>
        <classpath path="classes"/>
    </classloader>
    <taskdef name="myecho" classname="org.acme.MyEcho"
classpath="classes"/>
    <myecho>hello</myecho>
    <taskdef name="myecho2" classname="org.acme.MyEcho" />
    <myecho2>hello</myecho2>
</project>

The first myecho works, but the second does not.

Peter.
