![]() JMS is also useful when we are writing any event-based application like a chat server where it needs a publish event mechanism to send messages between the server and the clients. In this scenario, Java provides one of the solutions in form of JMS – and solves the exact same problem discussed above. There may be N number of such applications that are interested in such updates to B. ![]() When one application wants to send a message to another application in such a way that both applications do not know anything about each other and even they may NOT be deployed on the same server.įor example, one application A is running in India and another application B is running in the USA, and A is interested in sending some updates/messages to B – whenever something unique happens on A.
