•  An Object-Oriented, Component-based Approach to Migrating Legacy Systems View PDF    Download ZIP

Migration from a legacy to an object-oriented environment and component enterprise technologies is a difficult undertaking that faces numerous challenges. While some of the difficulties are of a technical nature, key challenges are in migrating development teams to new technologies, a new way of thinking and often to a new way of developing software altogether. This short white paper addresses the problems and the best practices in training teams who are migrating to the new technology, the associated thinking, and related process. The advice and the ideas in this paper represent state of the art methodologies and best practices used in successful adoption of the object-oriented and component development within the enterprise. The experiences are primarily from our work with a number of financial and insurance sector companies.

This paper focuses on modeling the problem domain. It is intended for developers and managers who use, or are considering using, the Unified Modeling Language in their development process. The paper assumes an elementary knowledge of object-oriented concepts and their use in OO modeling.

•  Model Driven Architectures For J2EE Systems View PDF    Download ZIP

In this paper we outline several best practices for using the Model Driven Architecture (MDA) to build enterprise systems on the J2EE platform that enable us to evolve our applications and adapt to change. We show how model driven development delivers J2EE components and systems based on object-oriented principles and J2EE design patterns that are able to support variations in functionality and realization required by strategic enterprise applications. Model and code examples are included.

•  Commercial Component Creation (EJB 2.0) View PDF    Download ZIP

This white paper will help component authors develop and enhance professional software components for server applications and for delivery on the "open market." Information covered in the document is based on our knowledge and the expertise of those component authors who have successfully established themselves in the component marketplace.

This paper was written for those developers who wish to create components based on Sun Microsystems® Enterprise JavaBeansT (EJB 2.0T) specification. We discuss the business benefits of using components and identify the functionality suitable for server-side component development in JavaT technology. Finally, we detail the EJB architecture and the environment in which these components can be used.
