A DESCRIPTION OF THE PROBLEM :
Has been replicated on J2SE 6 beta by JDIC project lead. He asked me to file a bug report. See
http://forums.java.net/jive/thread.jspa?threadID=17319&tstart=0

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1) When I use a html mailto in a html page, it correctly opens Yahoo Mail as the default mailer.
In the registry (Win XP), under HKEY_LOCAL_MACHINE\\SOFTWARE\\Clients\\Mail,
Yahoo Mail is listed.

2) I am trying the example from here, but get an exception:

https://jdic.dev.java.net/documentation/Examples.html
=======================================================
Case# 6: Launch the system default mailer and send the constructed message with UI or without UI.

import java.util.List;
import java.util.ArrayList;
import org.jdesktop.jdic.desktop.Desktop;
import org.jdesktop.jdic.desktop.DesktopException;
import org.jdesktop.jdic.desktop.Message;

public class MailTest {
public static void main(String[] args) {
Message msg = new Message();

List toList = new ArrayList();
toList.add("###@###.###");
msg.setToList(toList);

List ccList = new ArrayList();
ccList.add("###@###.###");
ccList.add("###@###.###");
msg.setCcList(ccList);

msg.setSubject("Hello");
msg.setBody("Test");

List attachList = new ArrayList();
attachList.add("C:\\test\\test.txt");
msg.setAttachmentList(attachList);

try {
// Send mail in UI mode.
Desktop.mail(msg);
} catch (DesktopException e) {
e.printStackTrace();
}
}
}



EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
I expected it to correctly open Yahoo Mail as the default mailer.

ACTUAL -
=====================================================
Exception in thread "main" java.lang.UnsupportedOperationException: Current system default mailer is not supported.
