I set up ActiveMQ Artemis consumer using spring-boot-starter-artemis and JMS. I also launched broker locally and I aim to configure these to communicate over OpenWire protocol. To constrain communication to that protocol I modified acceptor in broker.xml (protocols=OPENWIRE). It looks like that:
<acceptor name="artemis">tcp://0.0.0.0:61616?tcpSendBufferSize=1048576;tcpReceiveBufferSize=1048576;amqpMinLargeMessageSize=102400;protocols=OPENWIRE;useEpoll=true;amqpCredits=1000;amqpLowCredits=300;amqpDuplicateDetection=true;supportAdvisory=false;suppressInternalManagementObjects=false</acceptor>
However, unfortunately I'm getting the following error:
org.springframework.jms.UncategorizedJmsException: Uncategorized exception occurred during JMS processing; nested exception is javax.jms.JMSException: Failed to create session factory; nested exception is ActiveMQConnectionTimedOutException[errorType=CONNECTION_TIMEDOUT message=AMQ219013: Timed out waiting to receive cluster topology. Group:null]
How can I configure the client to use OpenWire protocol?
What is the default protocol they communicate on? Before I constrained the communication, Artemis Console was presenting the connection has been established on CORE protocol, which as far as I understand collective protocol. Which one i target protocol they really communicate on and how can I check this out?
The reason you're receiving ActiveMQConnectionTimedOutException is because you trying to use spring-boot-starter-artemis to connect to an acceptor which is configured to only support the OpenWire protocol. This will never work because spring-boot-starter-artemis depends on artemis-jms-client which will only use the ActiveMQ Artemis "core" protocol, not OpenWire.
You should configure the acceptor in broker.xml to support core, e.g.:
protocols=CORE,OPENWIRE
If you want the client to use OpenWire then you need to use the OpenWire JMS client library from ActiveMQ "Classic."
