NetWeaver Developer Studio is based on Eclipse

EclipseEclipse is an open source framework for Integrated DevelopmentEnvironments (www.eclipse.org)Eclipse has its roots in work done by IBMEclipse is an open consortium of J2EE and development environmentplayersSAP has joined the Eclipse consortium

NetWeaver Developer Studio is built on top of EclipseComplete set of tools with Eclipse user interface look and feelAllow customers and partners to extend the tooling environment throughthe plug-in architecture of EclipseOffer an individual and personalized access to the various developmenttools through Eclipse perspectives (customized tool sets)Seamless integration of all development tools into SAP‘s developmentinfrastructure (designtime repository, change management, softwarelogistics)

SAP‘s Java Development Infrastructure: Design principles

Most J2EE environments in the market offer a rather limited development infrastructure

A significant amount of manual work is necessary to setup a consistent Java development environment on a developer’s machine for each project

Idea: Combine a local and file based designtime architecture with the advantages of an integrated server-based environment such as ABAP


Cornerstones of SAP‘s Java DevelopmentInfrastructure

Component Model for Java DevelopmentSoftware architecture through software and development componentsComponent hierarchyManagement of component dependencies

Design Time RepositoryFiles and folder based repositoryDistibuted source code controlFlexible development landscapes

Component Build ServiceAutomatic & immediate build of changed and dependent componentsProvide consistent environment, automated update of local environment

Change Management ServiceAutomatic deployment to the J2EE runtime environmentPropagation of changes between different repositoriesMaintenance of (both SAP and customer) Java solutions

Component Model

Benefits of componentized Java developmentMastering complexity in distributed and networked Java development projectsManaging software components and their dependencies explicitlyBasis for a Java software delivery and maintenance

Software componentsAre the building blocks for SAP’s productsAre units that are installed and maintained at the customer’s siteHave their own release cycle and maintenance intervalsCompatibility between different software components is maintained in configurations

Development componentsAre containers for development objects (e.g. Java packages)Make up software componentsDependencies (“DC1 requires DC2”) can be defined between development components


Basic properties of development components

Java packagesUseful in the small, not sufficient in the largeDo not allow to restrict the use of public interfaces

Development ComponentsSupport decoupling, separate deliveryAllow to restrict visiblity, allow to analyze dependency

Nested components, Component hierarchy
