Message-oriented middleware has developed rapidly since its generation. In a distributed online transaction processing environment, it acts as a Communication Resource Manager (CRM, provides real-time, efficient, and reliable messaging services for distributed applications that span different operating systems and networks. At the same time, message-oriented middleware reduces the number of cross-platform applications.ProgramComplexity. In a system that requires reliable transmission, message-or

Message-driven bean in ejb3.0 is a Java Message Service (JMS) API used by developers to access enterprise message systems. The Enterprise message system can assist application software in message interaction over the network.
The JMS programming process is very simple. Generally, application a sends a message to a certain destination (destination) of the Message Server, and then the Message Server forwards the message to application B. Because application a and application B have no direct code
