1. JBoss dependency on JGroups
wdfink Feb 28, 2011 7:57 AM (in response to vivekbawge)I think there are no dependencies if you use the default configuration.
JGroups is used by caches and multicast stuff (autodiscovery and cluster communication).
I'm not sure whether port-binding manager will use it (think this will crash if it is needed and you start JBoss without jgroups)
But what is the reason for this, if jgroups is not used it will not be loaded by the classloader.
So there will no benefit at all.

2. JBoss dependency on JGroups
vivekbawge Mar 1, 2011 2:17 AM (in response to wdfink)Thanks Fink for your response. I appreciate it.
The reason for moving away from JGroups is - we are getting following exception/error during JBoss startup after fresh install of our application. This leads to failure of our JBoss apllications/services that use JMS. I could not get help about the resolving these errors/exceptions:
Errors are:

3. JBoss dependency on JGroups
welle Mar 1, 2011 2:29 AM (in response to vivekbawge)If you are not running in a cluster you could just make sure that "Clustered" is set to false in "$JBOSS_HOME/server/XXX/deploy/messaging/*--persistence-service.xml" (JBoss 5.1)
Are you running all or default configuration (or any else)

4. JBoss dependency on JGroups
vivekbawge Mar 1, 2011 3:29 AM (in response to welle)Thanks Anders.
Will jgroups be bypassed if I set Clustered propery to false?
I am running configuration specific to my application only.
Thanks,
Vivek

6. JBoss dependency on JGroups
wdfink Mar 1, 2011 4:42 AM (in response to vivekbawge)Does your configuration base on 'all' or 'production' (only EAP) configuration?
If yes you should check the differences to default to remove all cluster functions from your configuration.

7. JBoss dependency on JGroups
vivekbawge Mar 2, 2011 1:58 AM (in response to wdfink)Thanks Fink. That helps.
Anders, just disabling Clustering didn't help. JBoss wouldn't start after modifying this configuration.
BTW, can someone has insight on jgroups error pasted above?
Thanks,
Vivek

8. JBoss dependency on JGroups
welle Mar 2, 2011 2:12 AM (in response to vivekbawge)I just tried it on JBoss 5.1 (all configuration) and it worked for me!
Of course it doesn't stop other cluster services (HA-JNDI, EJB etc). I thought that your setup wasn't based on a clustered configuration and that you by mistake had copied a cluster aware messaging setup when you changed the database used as you described your problem was related to JMS.
Good to hear that your "up-and-running" now!

9. JBoss dependency on JGroups
wdfink Mar 2, 2011 2:41 AM (in response to vivekbawge)Do you have tried a non cluster configuration like 'default' and check whether the problem disapear?
Maybe you did not remove all dependencies to jgroups in your configuration.
Also you might start a fresh JBoss (without your application) with the default and the all configuration to verify whether the error raise here.

That thread has nothing to do with JGroups or the exception that you posted above.
