Messaging allows distributed communication which is loosely coupled. A component sends a message to the destination, and a recipient can retrieve that message from the destination. Though, the sender and the receiver do not have to be accessible at the same time in order to communicate. In fact, the sender doesn’t need to know anything about receiver; nor does the receiver need to know anything about sender. The sender and the receiver need to know only message format and the destination to use. In this respect, messaging changes from tightly coupled technologies, as Remote Method Invocation (RMI) that require an application to know a remote application's methods.
