Building Extensible Composite Applications with SAP Zusammenfassung

Building Extensible Composite Applications with SAP M. Steiner

This book teaches you how to build extensible Java applications and extend existing ones in a non-invasive manner. It illustrates the composites development on the basis of SAP NetWeaver Composition Environment, and provides a complete enhancement framework for Java applications similar to its pendant in ABAP. Many examples and practical tips help you understand the different extensibility concepts and support you in building your own custom framework. Design Principles Get to know the architecture of modern Java applications: the software design, application layers, and the toolset of SAP NetWeaver CE. Extensibility Concepts Discover the basic principles of extensibility concepts as well as the major requirements that extensibility techniques need to adhere to and how they can be addressed. Extensibility Framework Learn how to build a generic and re-usable extensibility framework and how to implement it into an existing application in a non-invasive manner. Real-World Use Cases All presented concepts and their underlying technologies are explained in detail and illustrated through sample business scenarios. Hands-on Information Experience best practices in modeling processes on the basis of numerous screenshots and source code listings, as well as step-by-step tutorials.
