I use this feature to assure, that only one client with this session-id is connected. i only wondered that the exception did not occure with the connect.
It happens on connect, but you are notified asynchronously as you are in fail safe mode. Note that you can max log in once for the user (loginName) and NOT for the session. 
To have more such 'singleton' clients you need to use different login names.


Best regards and thanks
Jürgen

P.S. What about my problem with  OSF/Motif timmers ?

As said in my posting from 2007-09-10 you should check your multi 
threading approach,
probably it is necessary to dispatch the code to the X-Window main loop 
thread,

Dear Jürgen,

the details of this feature are described here:

http://www.xmlblaster.org/xmlBlaster/doc/requirements/client.configuration.html 


(search "Assuring a client singleton " there)

First you should set

maxSessions='1'

in your use case!


You get the exception "errorCode=user.configuration.identicalClient" and

"Only the creator of session /node/ZBAA_/client/[EMAIL PROTECTED]/99 
may reconnect, access denied."



The reason is most likely that a login session of 
"[EMAIL PROTECTED]" exists already

please use the jconsole to check.

best regards
Marcel

To prevent identical users , i use setReconnectSameClientOnly(true) 
in SessionQos. It works, but the error is a bit confusing (see 
below) The connect is ok, but the following get has a exception.
