NWDI Resources

Expert Knowledge, Background Information, and Tips & Tricks for NWDI Users

Here you will find lots of useful information on NWDI-related topics, ranging from basics of component-based development and versioning mechanisms in the DTR to best practices in every-day work with NWDI and a success story of an early adopter of the NWDI. This is only a selection of NWDI related content - perhaps even what you may call a "best of" - however, it maybe worthwhile to search the SDN for other information, since this cannot be guaranteed to be complete.

NWDI Overview and User Experience

SAP Java Development Infrastructure Supports Developers from Project Start to Finish (PDF 607 KB) - This SAP Insider article from the early days of the development infrastructure overviews the topic when it was still called JDI and explains why it is a key differentiator between SAP NetWeaver Developer Studio and other approaches to a typical Java IDE. However, the concepts described are still valid for the NWDI as we call it now.

NWDI Background and Technology Basics

The Evolution of Development Infrastructure - Here, you'll find a discussion on what it means to use a central development infrastructure - not only for source code, but for all development steps. Why DTR? - The Design Time Repository (DTR) is the source code versioning system of NWDI/JDI created by SAP and based on the open standards of WebDAV and Delta V. Find out what is is different in DTR compared with other versioning concepts.

Component Model - Development in the NWDI is based on SAP's component model, which is used to structure applications as reusable components while serving as a basis for a new build process. The component model doesn't change the Java and J2EE objects you already know, but adds metadata that define the encapsulation of objects and their interfaces. Find out how this structured approach to development can change the way you work.

Development Landscapes - Software development in the NWDI is organized in tracks. Tracks define logical systems for the phases of development and consolidation and define the way objects are transported during all steps of the development of a specific release. Learn about what is possible with tracks, and how to structure an NWDI landscape to develop multiple releases of a product.

JDI Software vs. JDI Content - "On which release and SPS level do I have to run my JDI / NWDI server when I develop applications for a specific SP stack?" is an important question. Well, in principle the NWDI version is independent of the version of the software that you develop - read more in this blog.

Enhancements of the Change and Transport System u2013 Implications on Transports in a Heterogeneous SAP System Landscape (PDF 140 KB) - The Change and Transport System (CTS, SAP NetWeaver usage type AS ABAP) is enhanced with SAP NetWeaver 7.0 SPS 12 to be capable of transporting non-ABAP object types, such as those from the SAP NetWeaver usage types PI (Exchange Infrastructure), EP (Portal), etc. The article discusses the implications on transports for different usage types including the NWDI.

Best Practices for NWDI: Track Design for Ongoing Development - This blog provides recommendations for track design for development in the NWDI, focusing primarily on ongoing development with short release cycles.

Simplify DC structures for External Libraries - Starting with NW 7.0 SP13 a facet DC can be used to simplify DC structures a bit by allowing developers to combine the functionality of an "External Library" DC with a "J2EE Server Component Library" DC.

Isn 't it Groovy - extending the Development Component build with Groovy? This blog describes how to use Groovy instead of Java to write applications by integrate the groovy compiler into SAP's component build process.
