OOps, i believe you are mixing up the CORBA access and the
native access.

Only the CORBA access is implemented, the native access
interface will be specified hopefully in the next release.
(after package reorganization).

Usually you should only access xmlBlaster through the CORBA interface
Getting a login notification through CORBA is not yet implemented.

Yes, the login name of the publisher is delivered in the QOS,
for example:

  <qos>
     <sender>  <!-- The publisher login name of this message -->
        Phillipe
     </sender>
  </qos>

You don't need to parse this by yourself, the convenience class
org/xmlBlaster/client/UpdateQoS.java
has an access method sender() to retrieve it.
