Messages was not delivered

[slogger]

Hi gurus!!!

I have two machines with JBOSS 4.2.1.

OS Windows XP
jdk 1.5 (build 1.5.0_13-b05)
JBMessaging 1.4.0 SP3
JBRemoting 2.2.2 SP7

JMS provider was installed on only one machine and uses RDMS Oracle 10.2.0.

The second machine is just remote client. Message delivery was organized synchronously periodically in EJBTimer

(QueueReceiver::receive(timeout))

I am using Bean Managed Transaction and transacted queue session (connection.createQueueSession(true, 0))

Closing connection calling in finally block.

I am testing work stability under unstable network connection and unplugging network cable from jms cleint's machine periodically

After some time I get message on console (as an example):

2008-07-03 09:57:14,437 WARN [org.jboss.jms.client.container.ClientConsumer] Timed out waiting for last delivery 4 got -1

This message appears periodically in closing connection time (in my opinion).
After some time this message is not appeared, but meesages stay in queue table (jbm_msg) and is not delivering at all.

During of this timer continue work successfully and periodically creates session, attempts to receive messages and close connection.

There are not error messages on console.

A versions of JBMessaging and JBRemoting is identical on jms-provider and client machines.

After restart Jboss on client machine or Jboss whith Jms-provider the message delivering was started succesfully.

What do this message means and How can I resolve this problem?

Thanks in advance!

I'm not really sure what you're problem is, obviously if you unplug the network this will cause errors on either the client or server.

JBM works by sending messages to a client side buffer from which the client will consume messages from. This is for performance reasons. If you close the connection the consumer will wait to receive any messages that are still in the client side buffer, if at this point the server is unreachable the client will probably timeout waiting to ack the messages.

Hi, Andy!
Thank you very much for answer!

Yes, it throws exception like 'connection reset', but after this 'WARN [org.jboss.jms.client.container.ClientConsumer] Timed out waiting for
last delivery 4 got -1 ' issued and messages delivering is not working :-0(.

Did feature request http://jira.jboss.com/jira/browse/JBREM-891 fix this problem?

Please, sorry my English!

Again, i'm not sure what your problem is, I would expect these errors when unplugging a network cable.

It necessary for us to provide correctness of work on unstable network connections and recovery of delivering after losing connection.

I was found like one in http://jira.jboss.com/jira/browse/JBREM-947. It is solution of this problem?

JBM supports failover when clients lose connection to a node. This is all documented in the user docs. http://www.jboss.org/jbossmessaging/docs/index.html
