Inter-app Messaging

| | | |
Hi,
I'm relatively new to Java, but have been a programmer for decades. I
would like multiple instances of my Java app (on different computers on
the same local LAN) to communicate with each other through notifications
of some sort. For example, when instance 1 does a certain action,
instances 2, 3, and 4 should be notified about it so they can react
accordingly. I'm unaware of existing Java classes that deal with this
sort of thing, but I'm sure they must exist. Can someone please give me
a tip or two in this regard?

Use RMI.

| As suggested by a previous responder, you can use RMI to establish inter
JVM communication.
I would suggest that you also investigate the JMS (Java Messaging
Service). JMS is a standardized interface for messaging between loose
coupled applications. There several open source implementations of JMS: http://java-source.net/open-source/jms |
