For what it's worth, Artemis ships with a lot of JMS examples which use
jndi.properties.
Your jndi.properties is using this:
logMessages=queue.queues/logMessages
This looks wrong to me. I think it should be:
queue.queues/logMessages=logMessages
The first part ("queue.") tells the JNDI
log4J-2, JMS Appender requires JNDI bindings. Hence looking for a Spring
Boot, Artemis, JNDI example configuration.

Camel should be able to do this [1].

Hi
Does anyone know if it is possible to bridge between ActiveMQ 5 and another
broker using MQTT?
e.g.
producer > ActiveMQ ---MQTT---> Other broker (e.g. HiveMQ, Mosquitto, or
even another ActiveMQ) --> consumer
If so could you point me to any relevant documentation?

You're right. It is a rare event, and doesn't happen often enough for the
tear-down and new connection to be that big of an issue. Thanks a lot for
your help! :)

I would expect that a broker failure requiring you to connect to a
different broker would be a relatively rare event. The core JMS client has
functionality to transparently reconnect to the same broker in the case of

The message broker is a small part of a large product. So, unfortunately due
to the architecture, we HAVE to use 3 artemis servers, and can't do without.
Using 3 brokers is not for higher
Why are you using 3 VMs in the first place? Is that what you were using
before with the 5.x broker? If so, you may need to reassess your
architecture since Artemis' performance is significantly better for many
use-cases. You may not need so many brokers. Have you conducted any
performance tests?
I get it. Message expiry timer seems to be fine. Thanks again!

Hmm..so I have a question. Would you recommend me using a backup at all for
the scenario below -
I have 3 VMs as Artemis servers and I want all messages to be delivered to
all consumers on the servers. I'm currently using a cluster (ip1,ip2,ip3)
and I tear-down and create a new connection on a

I'm just getting familiar with this feature, but my understanding is that
it wouldn't provide connection failover. I believe you'd still need to
configure HA for that functionality.

Not every specific feature in the 5.x broker will be available in Artemis,
but you should be able to get something semantically equivalent (or at
least close).

Yes, I don't want messages to build up in the subscription and occupy memory.
I did use the message expiry timer, but here, we used ActiveMQ earlier and
want to migrate to Artemis, and in ActiveMQ we had an option of removing
offline durable subscribers with a timeout.

The 3 servers are VMs. So, federation might work as well. Currently, I'm
using a cluster and forwarding all messages to servers with consumers.
Unfortunately, using a cluster by itself without HA means that I have to
tear down the connection and create a new one, on every broker failure. So I
