COMPUTER APPLICATION FRAMEWORK

摘要

An application framework supports at least one application that includes one or more application components. The framework includes a directory providing a logical definition of the application. The logical definition is referenced by an application context identifier and provides logical definitions of the application components that make ap the application. It further includes references to physical instances of the application components. An application component includes a harness that contains an application component code segment for a predetermined application context. The harness forms an interface between the application component code segment and an exterior of the application component. The harness is operable to apply a predetermined mapping for the application context to map between an external format for communication external to the application component and an internal format understandable to the application component code segment. In a particular example, LDAP is used as the directory protocol and XML is used to communicate between the framework and the application components and between application components.
