  1. ActiveMQ Daniel

  2. JMS Client - An application written using 100% pure Java to send and receive messages. • Non-JMS Client - An application is written using the JMS provider's native client API to send and receive messages instead of JMS. • JMS Producer - A client application that creates and sends JMS messages. • JMS Consumer - A client application that receives and processes JMS messages. Concept

  3. JMS Provider - The implementation of the JMS interfaces which is ideally written in 100% pure Java. • JMS Message - The most fundamental concept of JMS; sent and received by JMS clients. • JMS Domains - The two styles of messaging that include point-to-point and publish/subscribe. Concept

  4. Administered Objects - Preconfigured JMS objects that contain provider-specific configuration data for use by clients. These objects are typically accessible by clients via JNDI. • Connection Factory - Clients use a connection factory to create connections to the JMS provider. • Destination - An object to which messages are addressed and sent and from which messages are received.

  9. Point-to-Point • Publish/Subscribe JMS Domains

  10. ActiveMQ acts as the middleman allowing heterogeneous integration and interaction in an asynchronous manner. • ActiveMQis a good solution to introduce loose coupling into an architecture and to provide heterogeneous integration. Why Use ActiveMQ?
