Comparison: ABAP / Java:Some highlights
ABAP
ÌOneframe(SE80)forall Design Time Tools
ÌHighly convenient infrastructure environment seamlessly
integrated into Development Workbench
ÌBuild environment,Deployment, SoftwareLogistics, ...
ÌProven environment for large-scale application development
ÌStrong support forSAPTechnologies
ÌStructured„logical“,not physical,presentationof all SAP Design
TimeObjects
Java
ÌLocal Development Environment
ÌEditing support: SyntaxHighlighting, CodeCompletion, ...
ÌOfflinedevelopment
ÌPrivate testenvironment(partially)
ÌSupportforStandardTechnologies
ÌJ2SE, J2EE, HTML, XML,...

5. ã2002 SAP Labs, LLC, JAVA101, Karl Kessler5
SAP Java IDE
Goal:Combine the advantages ofboth approaches
ÌProvide one frame foralltoolsandas integrationpointforall
infrastructure components
ÌProvide convenient integrated infrastructure environmentto
support large scale application development
ÌPreserve principleoflocalIDE
ÌLocal editing support
ÌOfflinedevelopment
ÌOptimalsupport for standardandSAPtechnologies
ÌLogically structured presentationof all Design TimeObjects
ÌGraphical editing support

Eclipse
nOpenSource project"donated"byIBM
nEclipse is itself writtenin Java
nEclipse is onlyaframework:Everything isaplugin!
nFormally definedExtensionPointsandPlugin dependencies
nVery small kernel(Platform Runtime):The framework itself is
implemented asasetofplugins
nOwnUIapproach(SWT /JFace)
nWorkbench plugin as generic
framework for any tool
nCompleteJava (J2SE) IDEcomes with
Eclipse
uSet ofplugins
uOpenSource
nEclipse is the basisof IBM‘s IDE WSAD
nMany vendors are providing Eclipse
plugins:Strong Industry drive

11. ã2002 SAP Labs, LLC, JAVA101, Karl Kessler11
Eclipse:Projects
nMultipleprojects can be
openedatthe sametime
nProject dependencies can be
declared
nWorkspace principle: a
workspace defines the scope
ofaccessible resources
nNoworkspace switch
atruntime

12. ã2002 SAP Labs, LLC, JAVA101, Karl Kessler12
Eclipse:PerspectivesandViews
nPerspective
uIs composedof allvisual components(views)for one aspectofthe
development
uExamples
lJavaperspective:Package view, Javaeditor,Outline pane forJava
source/class files
lDebug perspective: Javaeditor,thread display,breakpointlist, etc.
nQuick andeasy switch
nPerspectives are personalizable
uAdd/remove views
uCompose new perspectives from existing views
nPerspectives allow focussingon acertain aspectofdevelopment

TheSAP Framework
TechnologicalApproach
nUse Eclipse asJava IDE (J2SE)
nUse Eclipse asTool IntegrationPlatform foralldevelopment related
tools
uSAP Technology (WebDynpro, JavaDictionary, ...)
uStandardTechnologies not supported by Eclipse(J2EE, XML, ...)
uInfrastructure(Repository,Build, SoftwareLogistics, ...)
Drawbacks
nLack ofgenericModelAbstraction Layer
uNogeneric support for presentingDesign TimeObjectsin alogical(not
physical) way
uNobasis for generic graphics enabling
ServiceLayer not sufficient
nSWT /JFaceUIapproach insteadof Swing
uLittledocumentation
uAPIs lesswell-known thanswing
