I'm trying to reconfigure all my system to use the latest versions of remoting and JBM...Anyway, I'd like to know the default behavior of a MessageListener when a network failure occurs under Linux system...
I'm really lost since in windows platform I can detect network failures but not in Linux, with exactly the same configuration and software versions...
I would really appreciate your help.
Regards.

i think i am trying to set the classic topic/subscriber pattern, where one server is a publisher and the other servers, in my case only one of each, but if this work, there will be many subscribers to the topic. i am a bit confused on how each client of the topic gets notified of a publish message. i was thinking that thr bisocket adapter passed the message along, in a daisy chain style approach, but i am having trouble doing a put on one appserver and have message show up in the queue on another app

oh... now i get it... but consider the following situation... say i have 2 app servers load balanced by an apache server... after a request has gone to AS1 suppose it goes down... now my question is how does apache know whether AS1 has gone down and route the request to AS2 ( this will not be a case of ConnectException )... i mean this is exactly what i too have observed but i would like to know the reason of the behaviour...
does apache keep a track of the requests ?

The load balancer (Apache) is what handles failover. The request comes into apache and it decides how to handle it. If it sees the request's session is associated with a backend server that is no longer available, Apache picks a different server (i.e. fails over). If it passes the request through to a backend server and the request fails with a recoverable problem (e.g. ConnectException connecting to the backend server), it tries a different backend server (i.e. fails over).
