What is Subdeployment in WebLogic JMS?
A subdeployment is a mechanism by which JMS module resources (such as queues, topics, and connection factories) are grouped and targeted to a server resource (such as JMS servers, server instances, SAF agents, or a cluster).
What is ActiveMQ used for?
ActiveMQ is an open source protocol developed by Apache which functions as an implementation of message-oriented middleware (MOM). Its basic function is to send messages between different applications, but includes additional features like STOMP, JMS, and OpenWire.
