Network Failure undetected - Linux

[cbolanos]

Good morning, I have developed a JMS system. These are their main properties:

Jboss Messaging 1.4.0 SP3
Jboss Remoting 1.2.2 sp7
Jboss AS 4.2.2.GA
Linux debian 4

In a Jboss server there is a Queue, with a MDB listener on it, and a topic. When the MDB receives a message, pass it to the topic after processing it.

I have serveral clients who send messages to the remote Queue and receive messages from the topic, because all of them have a durable suscription.



This is the code of the JMS Client durable suscription

...
//Remote connections
AVMain.controller.updateProgressAction(35, "Starting Remote Connections...");
ic2 = new InitialContext();
AVMain.controller.updateProgressAction(45);
ConnectionFactory cf2= null;
cf2 = (ConnectionFactory)ic2.lookup(jndiConnectionFactory);
AVMain.controller.printLog("Found remote context: " + ic2.getEnvironment().get(ic2.PROVIDER_URL));
connection2 = cf2.createConnection(jmsUser, jmsPwd);
AVMain.controller.updateProgressAction(55);
AVMain.controller.printLog("JMS connection 2 created " + " of type " + connection2.getClass().getName());

ave = new AVExceptionListener();
//Obligatorio indicar clientid para poder crear una durable suscription
connection2.setClientID(clientId);
AVMain.controller.printLog("Client id " + clientId + "established");

connection2.setExceptionListener(ave);
session2 = connection2.createSession(false, Session.AUTO_ACKNOWLEDGE);
AVMain.controller.updateProgressAction(60);
AVMain.controller.printLog("Session2 created auto ack and without transatcions");

My problem is that in Linux enviroment, the client doesn't detect network failure (e.g if I disconect eth wire), however in Windows enviroment it does because the ExceptionListener throws an ConnectException. I've read a lot of configuring timeouts, keep alives, but i can't find the solution.

Please, could anyone help me.

Thank you for your great job.

Regards.

Hi, please check with the jboss messaging doc and see if you are using the correct version of jboss remoting. I know recent JBM 1.4 releases requiret remoting 2.2.2 or newer. Or may be you can try latest jbm 14 release? (which is 1.4.2.GA.SP1).

Sorry for my mistake. I'm using jboss-remoting 2.2.2 sp7

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.

You need to set an exception listener on the connection.

I've set the exception listener, and it throws an exception under Windows platform but not under Linux platform...
