F IGURE 9-5 Java four-System-Landscape with NetWeaver Developer Studio
The following sections discuss the main components of the SAP NWDI.
SAP NetWeaver Developer Studio
SAP NetWeaver Developer Studio is SAP's Java-based development environment. It is an
open-source project based on the Eclipse platform.
Change Management Service (CMS)
Change Management Service is part of the NWDI and helps transport Java objects between
the four systems of the Java landscape. It is similar to the SAP Transport Management Sys-
tem (STMS) of the ABAP systems.
Design Time Repository (DTR)
Design Time Repository is the part of the NWDI that acts as a central storage for all source
files in different formats. DTR provides a check-in and check-out mechanism for source
files so that developers can access the files from the repository.
Component Build Service (CBS)
Component Build Service is the part of NWDI that provides the central build environment.
The build process is based on the SAP component model. The objects are ready to be impor-
ted to the test system after a successful build, and then will be moved eventually to the pro-
duction environment for final deployment.
More details of SAP Java software logistics will be discussed in Chapter 12 .
