Developer's Guide (SAP Library - SAP NetWeaver Composition Environment Library)

Developer's Guide

SAP NetWeaver Composition Environment (SAP NetWeaver CE) offers design time and runtime capabilities for creating and running Java-based composite applications. The table below lists the available design time tools and their use:

CE Design Time Tools

Tool	Description
Enterprise Services Builder	The Enterprise Services Builder is a tool used to access the Enterprise Services Repository, which is the starting point for SOA-based development.
SAP NetWeaver Developer Studio	The SAP NetWeaver Developer Studio is based on the Eclipse platform and supports the development of standard Java Enterprise Edition (Java EE) components, the modeling of executable composite business processes using the process composer, the development of Web Dynpro applications, and the composition of services using the SAP Composite Application Framework (CAF).

In addition, SAP NetWeaver CE provides a Web-based environment for modeling user interfaces (Visual Composer) and designing user-centric business workflows (Guided Procedures).

Getting Started

The first section of the developer’s guide describes the layers composite applications typically consist of and introduces the development technologies and tools available in SAP NetWeaver CE by means of a use case. Each step in the use case links to more detailed information to guide you through this documentation.

More information: Guidelines for Developing Composite Applications

Documentation by Layers and Tasks

Aside from starting with the guidelines section, you can also find detailed information about each layer of SAP NetWeaver CE in the following sections:

Development Environment and Development Infrastructure

Section	Description
SAP NetWeaver Developer Studio Basics	How to work with the Developer Studio in general, its integrated SAP Management Console for basic administration and monitoring of the AS Java, and the Composition Designer perspective which is the central entry point to develop composite applications.
