Hello Patrick,
it is possible to do this using the classloader task of jtools
<taskdef name="classloadertask"
classname="org.apache.tools.ant.taskdefs.ClassloaderTask">
<classpath>
<fileset dir="${ivy.lib.dir}/classloadertask"/>
</classpath>
</taskdef>
<path id="all.mail.cp">
<fileset dir="${ivy.lib.dir}/mail">
<include name="*.jar"/>
</fileset>
</path>
<classloadertask classpathRef="all.mail.cp" loader="thread"/>
here is the snippet of my ivy.xml with the dependencies
<dependency org="sun" name="javamail" rev="1.3.3" conf="mail->default"/>
<dependency org="sun" name="jaf" rev="1.1.1" conf="mail->default"/>
<dependency org="sourceforge" name="jtools" rev="1.0-RC2"
conf="classloadertask->default">
<artifact name="ant-classloadertask" type="jar"/>
</dependency>
so you do not need to redefine the mail task but put artificially
activation.jar and mail.jar on the thread class loader.
Regards,
Antoine

Hello,
Is it possible to use the<mail> task without having activation.jar
and mail.jar in the ant lib folder?
I tried to redefine the mail task this way:
<taskdef name="mymail"
classname="org.apache.tools.ant.taskdefs.email.MimeMailer">
<classpath>
<pathelement location="${ant.home}/lib/ant-javamail.jar" />
<!--
same with and without this line -->
<pathelement location="a/mail.jar" />
<pathelement location="a/activation.jar" />
</classpath>
</taskdef>
But it did not work. I keep on getting the following error:
D:\tmp\build.xml:7: taskdef A class needed by class
org.apache.tools.ant.taskdefs.email.MimeMailer cannot be found:
javax/mail/MessagingException
using the classloader AntClassLoader[D:\tmp\a\activation.jar]
