....call, cross language procedure call, and remote procedure call. This restriction allows them both to develop their equivalent of wares in standard programming languages and to infer and generate the packager to be used. This work and its later extension to handle mismatches in event systems [3] inspired the channel maps used in Flexible Packaging. Contemporary projects have also influenced the research on Flexible Packaging. The Flexible Packaging framework for creating packager makers and packaging experts is a locally implemented variation on Batory, Lofaso, and Smaragdakis Jakarta ....

....this work, we are concerned with the technology and methods for integrating an event based application that is a synthesis of existing systems. 1 2 Problems and Possible Approaches Several problems arise when integrating separately developed but related event based distributed applications (see [2] for a detailed example) ffl Application Structure The application structure may be different, some components or modules from the existing applications may not be needed in the composite application. ffl Module Names Since the existing applications are built separately, there maybe conflicts ....

....distributed graphics support. 9] None of these systems supports the reuse of legacy VEs. This work draws on the experience with code generators, interconnection tools, and packagers. Hofmiester and Purtilo [7] have built the SURGEON system for dynamic reconfiguration and Chen and Purtilo [2] have built tools for mapping events in event based interconnected systems. The gluing together of disparate heterogeneous distributed systems forms the foundationon which we built this work. Using standard interconnection abstractions makes the development of a software engineering environment ....

....a set of relations among existing event based distributed applications in order to support the interoperation between them. We have defined a composite interaction specification language called ENimble, which allows programmers to describe the way they want the existing applications to interact [8]. In this language, we specify applications from which the the composite application is built. Modules that no longer need to be in the composite application are identified. If there is a conflict between module names, we can rename the software modules. When there are different event naming ....

Hofmiester and Purtilo [7] have built the SURGEON system for dynamic reconfiguration and Chen and Purtilo [3] have built tools for mapping events in event based interconnected systems. 3 ZUBIN: THE SOFTWARE ENGINEERING ENVIRONMENT We have built an environment towards meeting these requirements. It has three facets: a tailored methodology that exploits the software tools, an interconnection generator ....

....implement the interaction defined in the IL between existing VEs. The event interaction between the modules is described in the IL. The software engineer then uses the event mapping tool to create coercion modules that combined with the software bus and VE code make up the execution environment. CP95] For example, the change location event in the Apache simulation will map to the BIFV update display event. Methodology The methodology includes the way to approach the analysis of legacy VEs prior to writing the IL modules, as well as the decisions of what to incorporate in the IL modules. We ....
