[xmlblaster] use of setReconnectSameClientOnly
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.

[xmlblaster] dead lock
Hi, I'm using Xmlblaster 1.6. I restarted, some connected clients and unfortunately one of my client never connects back :( Even if I restart several times this client, it never successes to connect. That's why I dumped the threads' stack on the server side and I found the following dead lock (see below) Is there a way to avoid it ? Thanks, Xavier.

Re: [xmlblaster] use of setReconnectSameClientOnly
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 Jürgen Prinz wrote: To prevent identical users , i use setReconnectSameClientOnly(true) in SessionQos.

Re: [xmlblaster] dead lock
Xavier Roques wrote: Hi, I'm using Xmlblaster 1.6. I restarted, some connected clients and unfortunately one of my client never connects back :( Even if I restart several times this client, it never successes to connect. That's why I dumped the threads' stack on the server side and I found the following dead lock (see below) Is there a way to avoid it ? Yes, this is a dead lock, i have coded now a lock free variant but i need some more testing if the auto-disconnect (from ping timer) and reconnect (from your client) simultaneously have other impacts ... I'll send a followup as soon as the fix is committed, Marcel Thanks, Xavier.

Re: [xmlblaster] use of setReconnectSameClientOnly
Jürgen Prinz wrote: 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, best regards Marcel Marcel Ruff wrote: 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 Jürgen Prinz wrote: To prevent identical users , i use setReconnectSameClientOnly(true) in SessionQos.
