Building Extensible Composite Applications with SAP

Composites allow SAP customers to develop new business processes with additional business logic on top of the existing enterprise services. But what happens when you upgrade your system? Will your own applications still work or has the system replaced your modifications? This book will teach you how to develop extensible Java applications and extend existing applications in a non-invasive manner. It illustrates the composites’ development on the basis of the Composition Environment, and as its biggest asset, the book provides a complete “enhancement framework” for Java applications similar to its pendant in ABAP. All presented concepts and their underlying technologies are explained in detail and illustrated by sample business scenarios. Additionally, the book explains best practices in modelling processes and contains numerous screenshots and source code listings as well as step-by-step tutorials.
