SAP Java Development Environment
SAP Java development uses an approach where individual developers work in their own
local environments by checking out the code from a central environment and when the de-
velopment is ready, they will check in the code version to be integrated with respect to ver-
sion management in a central development system. This approach is supported by the SAP
NWDI, which includes a local development environment installed on each developer PC
called NetWeaver Developer Studio and central services such as DTR, CBS, and CMS. SAP
NWDI helps in large-scale Java development projects where multiple developers are work-
ing in a coordinated manner to build Java applications that serve a particular business func-
tion.
Each developer has NetWeaver Developer Studio installed on his or her laptop that includes
a local J2EE environment. Each developer tests the Java code locally and ensures that the
code is working before checking it in to the central environment.
