JMS, which stands for Java Message Service also referred to as Messaging Oriented Middleware (MOM), defines standards for reliable enterprise messaging. As JDBC provides access to many different relational databases, in the same way, JMS provides vendor-neutral access to enterprise messaging systems.
JMS clients are Java applications that make use of JMS, and the JMS provider is the name given to the messaging system that handles the sending and receiving of messages.
The JMS client that sends a message is known as a producer, and the JMS client that receives the message is known as a consumer.
JMS provides asynchronous messaging, i.e., a JMS client can send messages without waiting for its reply.
