NotificationListener not receiving start/stop/restart app notifications

    NotificationListener not receiving start/stop/restart app notifications

    --------------------------------

    Hi all,

    I have an small issue with a JMX client application, I have developed a NotificationListener to read the notifications sent by Websphere when any action is done, everything seems to be working fine but I am having problems to receive notifications when I start, stop or restart an application. If I ask websphere, for example, to sync a cluster I receive all the notifications but if I try to start, stop or restart an application I don't receive any notification at all... Initially I asked my listener to read all the RasLoggingService notifications (objectName = /"WebSphere:type=RasLoggingService,*/"), but finally, since I don't receive anything, I asked it to listen to all kind of messages (objectName = /"Websphere:*/"), but nothing seems to be received anyway.

    Does anyone know why this could be happening? I guess this could be a configuration issue but I am not being able to discover it at all.

    Thanks a lot in advance.

    PS: This is only happening to me with a test DMGR server (v6.0.2.25), if I try it in my local DMGR server (v6.1.0) and with another local WAS server (v6.0.0.1) everything works fine.

    After some further tests I can see that the NotificationListeners gets /"blocked/" only when I try to filter any of the TYPE_RAS notifications, if I try to process the TYPE_J2EE_STATE notifications alone, everything is working fine, but as soon as I try to also filter any of the TYPE_RAS messages it gets /"blocked/". So it seems in this server there must be any issue with the Ras Logging messages, although they are being created since I can see them in the /"Runtime events/" section within the websphere administrative console...

    Any advice????
