1 Creating Web Applications for SAP BW and SAP Enterprise Portal with the SAP Java IDE (A Sneak Peek!) Sam Tingleff Technology Product Management SAP Labs

2 Agenda SAP Java IDE Overview Web Dynpro and the J2EE Toolset Java Dictionary The Portal Development Kit Conclusion SAP AG 2003, slide 2

4 What Is the SAP Java IDE? New tool from SAP for developing enterprise applications Full desktop application does not use SAPGUI The Java development tool for SAP Released with SAP Web Application Server 6.30 Will be used for Web application development on Web AS 6.30 Portal component development Other Java development SAP AG 2003, slide 4

5 ABAP Workbench vs. SAP Java IDE ABAP ABAP JAVA Server-oriented Design and runtime objects stored in same database SAP System determines scope Environment/Infrastructure Large Scale Application Support Local Editing Java Operates on Local File System Design and runtime objects separated Support for Standards Support for SAP Technology Development environment organized in local projects Offline Development Private Test Environment SAP AG 2003, slide 5

6 ABAP vs. Java: Some Highlights ABAP Java One frame (SE80) for all design-time tools Logistics seamlessly integrated into the Development Workbench Build environment, Deployment, Software Logistics, etc. Supports SAP technologies Structured logical, not physical, presentation of all SAP designtime objects Local Development Environment Editing support: Syntax Highlighting, Code Completion, etc. Offline development Private test environment (partially) Support for Standard Technologies J2SE, J2EE, HTML, XML, etc. SAP AG 2003, slide 6

7 Goal: Combine the Advantages of Both Approaches Provide one frame for all tools and as integration point for all infrastructure components Provide convenient integrated infrastructure environment for large-scale application development Preserve the principle of local IDE Provide local editing support Enable offline development Support standard and SAP technologies Logically structure the presentation of design-time objects Enable graphical editing SAP AG 2003, slide 7

8 Overall Java Development Infrastructure Tool Integration Platform Software Logistics (SL) Java DDIC J2EE Web Dynpro Web Service DTR/CBS/SL Integration Component Build Service (CBS) Deploy Run Time J2EE Server Graphics Tool Service Layer Generic Model Abstraction Layer Local File System Design-time Repository (DTR) SAP AG 2003, slide 8

9 IBM s Eclipse Is the Foundation Open Source project "donated" by IBM Written in Java Eclipse is only a framework Very small kernel (Platform Runtime) Everything is a plug-in! Own UI approach (SWT/JFace) Eclipse comes with a full Java (J2SE) IDE comes with Eclipse SAP AG 2003, slide 9

10 IDE Overview: Java and Debug Perspective Java Perspective Debug Perspective SAP AG 2003, slide 10

11 IDE Overview: IDE Features Refactoring features Move/rename classes and methods Repackage Extract methods Surround with try/catch Pretty printing Configurable Code completion (IntelliSense) Import management Configurable Search features References Definitions Read/write access Javadoc help as tooltip SAP AG 2003, slide 11

12 SAP Java IDE: Benefits & Considerations Java will not replace ABAP! Our goal is to provide maximum flexibility to customers Currently 3-4 million registered Java developers Often taught as a first language in schools When should you use Java? ABAP still recommended for core business logic Java excels at user interfaces, integration, etc. Depends on the project and your development team SAP AG 2003, slide 12

13 SAP Java IDE: Prerequisites & Availability Prerequisites SAP Web Application Server 6.30 Sun JDK 1.3.1/1.4 Java knowledge and experience Will be available via the service marketplace SAP AG 2003, slide 13

15 What is Web Dynpro? One component of the SAP Java IDE Graphical design tool for building Web-based business applications Conversion tool to Web-enable ABAP/Dynpro programs Key features Complete toolset based on the Eclipse IDE Graphical design of view composition and navigation flow WYSIWYG view designer Standard Java editor for implementing event handlers Efficient development cycle (edit build deploy run) SAP AG 2003, slide 15

16 What is Web Dynpro? (cont d) Web Dynpro User interfaces are Professional looking Easy-to-use Highly interactive Web Dynpro IDE Model and develop presentation logic Design and compose user interfaces Backed by usability patterns Based on business datatype information Runtime services Open standards, runtime infrastructure Java and ABAP (JSP and BSP*) Tag libraries Device independence Internationalization Easy to deploy and maintain * ASP planned Web Dynpro Presentation Layer Business Layer Tag libraries BSP, JSP* J2EE/ABAP SAP Web Application Server SAP AG 2003, slide 16

17 Web Dynpro Benefits Improves User Experience Browser-based front end Flicker-free screen, minimal refreshes Minimal response times Built-in personalization 508 accessibility compliance Web Dynpro Tools.NET Web Dynpro Runtime J2EE Web Dynpro Metadata ABAP Strategic development Web Dynpro components can be reused Supports Web Services & Databinding Separate Layout & Programming Logic Independence From platform From UI technology Multi-Device Internet SAP AG 2003, slide 17

18 What is the J2EE Toolset? Contains creation wizards for Projects: EJB, EJB Assembly, Web, Web Assembly, Enterprise Apps Objects: EJB, Servlet, JSP, Filter, Listener, HTML SAP AG 2003, slide 18

19 What is the J2EE Toolset? (cont d) LAN SAP J2EE Engine SAP J2EE Engine Deployment Developer s PC Includes a Local Test & Debug Environment Specify server settings in the Preferences" page Start/stop the local J2EE Engine from the J2EE View Normal or debug mode Directly test or debug servlets / JSPs on your local server SAP Java IDE Local Testing and Debugging SAP J2EE Engine SAP AG 2003, slide 19

21 Agenda SAP Java IDE Overview Web Dynpro and J2EE Tools Java Dictionary The Portal Development Kit Conclusion SAP AG 2003, slide 21

22 What is the Java Dictionary? Similar to the ABAP data dictionary Will be part of Web AS 6.30 Will contain a datatype repository Independent of application code Content can be used in various places Database persistence Fields of a Web Dynpro form SAP AG 2003, slide 22

23 Simple Type Example SimpleType Core datatype information Restriction base Restriction base Restriction base Constraints UI-related information Database-related information Web Service-related information <simpletype name='airline'> <restriction base='string'> <maxlength value='3'/> <enumeration value='lh '/> <enumeration value='ua '/> <enumeration value='aa '/> </restriction> <annotation> <fieldlabel value='airline'/> <col_label value='airline'/> </annotation> <annotation> <notnull value='true'/> </annotation> </simpletype> SAP AG 2003, slide 23

24 Java Dictionary Benefits Datatypes can be used in all layers of application development Enhanced application portability Development platform (Web Dynpro for ABAP, Java,.Net) Database platform Centralized source definition and maintenance Reuse Central points for extension/modification Services are attached centrally Seamless integration into the Java IDE Java IDE based on Eclipse Local, component-based development process Fits well into declarative frameworks like Web Dynpro SAP AG 2003, slide 24

25 Database Layer SAP s Goals Support several RDBMSs Platform-independent access to data Platform-independent definition of database objects Performance Caching of data Caching of statements SQL trace Fit into local development process Definition and deployment of database objects Checked usage of database objects Support relational persistence + object relational persistence SAP AG 2003, slide 25

26 Database Layer Open SQL for Java Java program Relational Persistence Object Relational Persistence unchecked SQL Open SQL/ Native SQL Open SQL/ JDBC Open SQL/ SQLJ Open SQL Engine SQL Processor DB access layer EJB CMP JDO Table buffer Table catalog Statement cache portable SQL Vendor JDBC Open SQL for Java SQL trace RDBMS SAP AG 2003, slide 26
