1	The (new) Internet Enabled SAP Quickly, the evolution, and a roadmap for you
2	Topics Internet Transaction Server ESS/MSS Web Studio – Limitations Flow Logic Workplace TopTier – Iviews, Drag and Relate Web Application Server – Business Server Pages Object Oriented ABAP SAP Java (J2EE) Server Netweaver – Netweaver Studio Portal Development Kit – Iview Studio Business Packages – xApps ABAP developer to SAP developer roadmap
3	Internet Transaction Server ITS “scrapes” the SAPGUI screen elements. The generated HTML screen has these elements. The button clicked on HTML eventually invokes the screen flow logic of SAPGUI
4	Internet Transaction Server The templates could be modified using Web Studio or SAP Studio Supported client ‘Branding’ Business HTML WEBGUI could be used for most Applications
5	Internet Transaction Server ITS Flow Logic Programming used RFCs The HTML template could use open technologies like CSS, DHMTL, JavaScript The FLOW FILES controlled the RFC calls and the screen flow
6	ITS - Limitations Screen elements not displayed well and sharp Limitations with Control elements like ALV and Table Controls Limitations with Front-end functionality like Excel download, etc. Performance Very limited Persistence memory Not an open technology IIS and Windows platform dependant
7	Workplace Portal Solution Single Sign On Role based CUA MiniApps Metadata
8	TopTier Integration Iview Servlet Drag and Relate Servlet
9	Web Application Server - BSP Business Server Pages ABAP Code within HTML Now MVC Architecture Web AS as a server that serves HTML – integrated authentication Optional Business HTML frontend design SE80 as IDE Integrated with SAP Transport Mechanism for code and mimes Via BSP, ABAP stack of SAP Web AS meets JSP on the J2EE side
10	Advances in ABAP Object Oriented – Classes and Methods: Polymorphism, Encapsulation, Inheritance BADI, Controls Framework, Classes for HTML interfacing, etc. Example: Employee as an Object Unicode XML Transformations Shared Objects, New Debugging Tools, Memory Monitor, etc.
11	SAP Java Server Limited ABAP community; flourishing J2EE Community Acquired InQMy – developed and refined J2EE 1.3 Certified by Sun Microsystems Base of SAP Portals, and forms J2EE stack of Web AS 6.3, and onwards
12	Netweaver WAS – ABAP Engine + J2EE Engine – preserves investments Exchange, BI and Portal Infrastructure Browser or Application Client/SAPGUI Java IDE – Open Source Eclipse based Java Dictionary, Open SQL for Java Web Dynpro – MVC xApps – Composite Application Framework
13	SAP Portals Roles, Worksets and Iviews Now runs on J2EE Engine PDK or Business Packages PDK JBuilder or Netweaver Studio Business Packages – SAP & non-SAP RFCs. Also IAC, ISR, BSP JSP/Servlets -> Web Dynpro
14	Learning Roadmap Web JSPs ~ BSPs Servlets ~ BSP Controllers Business Programming Enterprise JavaBeans ~ BAPIs/RFCs SAP Enhancements for Business Development Java Dictionary ~ ABAP Data Dictionary Open SQL for Java ~ Open SQL for ABAP Java Development Infrastructure ~ ABAP Development Infrastructure
15	Next….. Learn ABAP Objects and Object Oriented Programming Learn BSP – the ABAP Objects based web programming Take basic Java courses Take J2EE Classes – including JSP/Servlets and SAP’s own J2EE Classes…. Get familiar with the different IDEs
