Abstract: In accordance with an embodiment, a system and method provides a dynamic clustered messaging service in an application server environment. A cluster includes one or more servers operating within the application server environment and is configured to vary a number of the servers based on a service load of applications running on the cluster. The number also varies based on failure and restart of the servers. A messaging service for communicating messages between components of the applications includes instances of messaging service artifacts running on the one or more servers. A placement engine operating on the cluster is configured to migrate the instances of messaging service artifacts between the one or more servers based on a set of rules as the number of the one or more servers in the cluster expands and contracts and as a number of the instances of messaging service artifacts expands and contracts.
