Hello John,
I believe the parameter you are looking for is: "initialConnectAttempts=-1" in
addition to what you have already configured. The default value is 0, meaning
try once and throw an exception if that does not work (which is what you are
seeing in your post).
Br,
Anton

Subject: Artemis: How to make maximally resilient/retrying connection
CAUTION: This email originated from outside of the organization. If suspicious,
please report it.
Greetings,
I'd like to ensure maximal resilience of the broker connection, specifically:
* If the Artemis broker is not running when our services start, the
connection attempt hangs until the broker is available, and then returns the
connection
* If the Artemis broker fails while our services are running, our services
consumers and producers will hang/block until the broker is available
I *thought* I was doing that by using the URL
tcp://localhost:61616?reconnectAttempts=-1
However, I find that the connection attempt just throws an exception
java.lang.RuntimeException: Failed to create JMS connection to
'tcp://localhost:61616?reconnectAttempts=-1'

Can someone help me understand how this is designed to work, and how best to
achieve the two goals above?
Thanks
