It is confusing what is used for the session clustering between activeMQ and JGroups in wildfly 23

[joshlee]

Dear all the wildfly users around the world, I really want to know which one will work with either activeMQ or JGroups

 

https://docs.wildfly.org/23/High_Availability_Guide.html#JGroups_Subsystem

In this document, I understood JGroups will be used for the session cluster.

But https://access.redhat.com/documentation/en-us/red_hat_jboss_enterprise_application_platform/7.3/html/configuring_messaging/clusters_overview

In this document, It is telling me 'JBoss EAP messaging clusters allow groups of JBoss EAP messaging servers to be grouped together in order to share message processing load'

In my opinion, It seems like activeMQ and JGroups are pretty similar to each other...

and then I have one more quetion..

Configuring a Cluster Connection for Duplicate Detection in https://access.redhat.com/documentation/en-us/red_hat_jboss_enterprise_application_platform/7.3/html/configuring_messaging/clusters_overview

is saying  'The default value for cluster-user is ACTIVEMQ.CLUSTER.ADMIN.USER and the default value for cluster-password is CHANGE ME!!'

...

if activeMQ is used when setting session cluster, Do I have to set cluster-user and cluster-password ??

I really want to understand the concept of session cluster in wildfly...
