Abstract: In general, in one aspect, the invention provides a modular application collaborator for providing inter-operability between applications including a plurality of connectors for communicating with a like plurality of applications and an interchange server. The interchange server includes an application collaboration module and service module. The service module transfers messages between connectors and the application collaboration module. The application collaboration defines the inter-operability between two or more applications. The interchange server service module includes a transaction service and an error service. Transactions are executed in the application collaboration module and the transaction service records each action and a compensating action for undoing an associated action.

Abstract: An agent-adapter architecture used in systems and methods to integrate applications of the type normally deployed across a networked enterprise. A plurality of adapters, each of which is adapted to perform a discrete function associated with respective ones of the plurality of enterprise applications is encapsulated by an agent. The agent is extensible, including one or more embedded objects, each of which is adapted to perform a discrete function that may or may not be associated with respective ones of the plurality of enterprise applications.
