SAP's Java IDE is based on Eclipse and provides tools for developing Java applications on SAP systems. It includes a J2EE toolset with support for standard Java EE features and integration with SAP's J2EE engine. A model abstraction layer and graphics layer allow development objects to be logically presented and diagrammed. The tools are integrated with SAP infrastructure components like the design time repository, build service, and software logistics.

Comparison: ABAP / Java: Some highlights
ABAP
Ì One frame (SE80) for all Design Time Tools
Ì Highly convenient infrastructure environment seamlessly
integrated into Development Workbench
Ì Build environment, Deployment, Software Logistics, ...
Ì Proven environment for large-scale application development
Ì Strong support for SAP Technologies
Ì Structured „logical“, not physical, presentation of all SAP Design
Time Objects
Java
Ì Local Development Environment
Ì Editing support: Syntax Highlighting, Code Completion, ...
Ì Offline development
Ì Private test environment (partially)
Ì Support for Standard Technologies
Ì J2SE, J2EE, HTML, XML,...

SAP Java IDE
Goal: Combine the advantages of both approaches
Ì Provide one frame for all tools and as integration point for all
infrastructure components
Ì Provide convenient integrated infrastructure environment to
support large scale application development
Ì Preserve principle of local IDE
ÌLocal editing support
ÌOffline development
Ì Optimal support for standard and SAP technologies
Ì Logically structured presentation of all Design Time Objects
Ì Graphical editing support

Eclipse
n Open Source project "donated" by IBM
n Eclipse is itself written in Java
n Eclipse is only a framework: Everything is a plugin!
n Formally defined Extension Points and Plugin dependencies
n Very small kernel (Platform Runtime): The framework itself is
implemented as a set of plugins
n Own UI approach (SWT / JFace)
n Workbench plugin as generic
framework for any tool
n Complete Java (J2SE) IDE comes with
Eclipse
u Set of plugins
u Open Source
n Eclipse is the basis of IBM‘s IDE WSAD
n Many vendors are providing Eclipse
plugins: Strong Industry drive

11. © 2002 SAP Labs, LLC, JAVA101, Karl Kessler 11
Eclipse: Projects
n Multiple projects can be
opened at the same time
n Project dependencies can be
declared
n Workspace principle: a
workspace defines the scope
of accessible resources
n No workspace switch
at run time

12. © 2002 SAP Labs, LLC, JAVA101, Karl Kessler 12
Eclipse: Perspectives and Views
n Perspective
uIs composed of all visual components (views) for one aspect of the
development
uExamples
l Java perspective: Package view, Java editor, Outline pane for Java
source/class files
l Debug perspective: Java editor, thread display, breakpoint list, etc.
n Quick and easy switch
n Perspectives are personalizable
uAdd/remove views
uCompose new perspectives from existing views
n Perspectives allow focussing on a certain aspect of development

n Refactoring features
u Move/rename classes and
methods
u Repackage
u Extract methods
u Surround with try/catch
n Pretty Printing
u Configurable
n Code completion (IntelliSense)
n Import management
u Configurable
n Search features
u References
u Definitions
u Read/write access
n Javadoc help as tooltip

n Incremental Build
n Ant based build support
n Support for building

Eclipse: PlugIn Development
n Runtime Workbench
udebug possibility
n PlugIn Development
Environment (PDE)
n Lazy initialization of
PlugIns
n Easy deployment
n „Everything is a PlugIn“
uPlugIn dependencies
uPlugIn versioning
n Extension Point technology
uEvery PlugIn extends other
PlugIns at predefined
Extension Points
uEvery PlugIn can provide
Extension Points

Eclipse: Presenting the Workspace
n Direct presentation of files and folders structure (Resource
Perspective)
n Special abstraction layer for Java Perspective:
package -> class -> method / attr.
n No generic abstraction layer

The SAP Framework
Technological Approach
n Use Eclipse as Java IDE (J2SE)
n Use Eclipse as Tool Integration Platform for all development related
tools
u SAP Technology (WebDynpro, Java Dictionary, ...)
u Standard Technologies not supported by Eclipse (J2EE, XML, ...)
u Infrastructure (Repository, Build, Software Logistics, ...)
Drawbacks
n Lack of generic Model Abstraction Layer
u No generic support for presenting Design Time Objects in a logical (not
physical) way
u No basis for generic graphics enabling
Service Layer not sufficient
n SWT / JFace UI approach instead of Swing
u Little documentation
u APIs less well-known than swing
