Detection of a failure in a multi-system application, includes detecting a first message between a first system and a second system and creating a connection object representing a connection between the first system and the second system. Thereafter, connection status is monitored with the connection object to detect a connection or system failure. The same connection object is used for all subsequent messages between the first system and the second system. The multi-system application uses service objects on the first and the second system, and when a connection or system failure is detected, failure handling is initiated, including notifying all service objects of the failure.

Automatic notification of connection or system failure in asynchronous multi-tiered system by monitoring connection status using connection objects

Routing asynchronous state changes in a multi-processing system having an end user system, a central application server system and an endpoint system, includes detecting a state change with a service object on the endpoint system, sending a notification to an associated service proxy object on the central application server system notifying the associated service proxy object of the state change, sending a notification to an associated distributed service object which is an owner of the service proxy notifying the associated distributed service object of the state change, sending a notification to an associated distributed service proxy object on the end user system notifying the associated distributed service proxy object of the state change, and posting an event to an associated owner window of the distributed service proxy object using a window identifier including sending a notification to the associated owner window notifying the associated owner window of the state change.
