  Most of the communications between components that you have seen so far are synchronous: one class calls another, a managed bean invokes an EJB, which calls an entity, and so on. 

   Message-oriented middleware (MOM) is software (a provider) that enables asynchronous 

messages between heterogeneous systems. It can be seen as a buffer between systems that 

produce and consume messages at their own pace

    JMS is a standard Java API that allows applications to create, send, receive, and read messages 

asynchronously
