[Victor Ramen]

Conceptually, what is the difference between these 3:
Message Queue
Message Broker
JMS Resource Adapter.

Hi , sorry frankly very big question to answer , and if even people wrote lines , that will be of no use . Go throughly through each of these Topics .

Message Broker - The message-oriented middleware server that hosts messaging destinations (i.e., queues and topics) for the purposes of asynchronous communication. Sometimes known as a queue manager
Message Queue - A messaging destination that uses a queue data structure to hold messages and is hosted by the message broker. The alternative to a queue is a topic which provides publish/subscribe semantics.
Resource Adapter - A Java EE Resource Adapter is a component that allows communication between a Java EE application and an enterprise information system such as a database server, a messaging server, a CRM server, an ERP server, etc.

More information about JMS and related concepts can be found in the The Java Message Service API.

Hope that helps.
