Method for controlling communication in distributed application of services e.g. Java message service, involves controlling exchange of message between services, and providing state machine for defining state of message exchange

摘要

The method involves controlling exchange of message between two services using a clear trace identification of a message object stored in a metadata in a control layer (200) of distributed application of services (900), where the object comprises a format suitable for message exchange between the services over a message exchange system. A state machine is provided for defining a state of message exchange of the message object. A service query is produced through one of the services. The service query is transferred form the service to a service proxy. Independent claims are also included for the following: (1) a computer program for controlling a communication in a distributed application of services (2) a machine readable data storage medium with a computer program for controlling a communication in a distributed application of services (3) a computer system for controlling a communication in a distributed application of services.
