Sap netweaver web dynpro java deploy12/28/2022 Implemented service is deployed to SAP ABAP application server and is available for use after few configurations in SOAMANAGER. This metadata becomes available to SAP ECC (On activation of Service “Interface in ESR) in transaction SE80 where server proxy is defined by using imported interfaces. SAP ECC provides environment to implement enterprise services by using metadata defined in SAP ESR. SAP ESR leverages SAP PI – IR features to design Data Types, Message Types and Service Interfaces for WS definition.ĭesigned services metadata is moved to SAP ECC for business logic implementation. SAP ESRprovides design environment for modeling and design of enterprise services metadata. Also, the developer can get an access to the JDI by importing a single development configuration file.įinally, Web Dynpro is a revolution and leap in the UI development world and it will minimize the cost, time and effort in the cycles of training and implementation.Web Services best practices in SAP CE 7.x platform and overview of used components JDI could be described by three elements which are: Design, Time, and Repository (DTR) which handles file versioning to ensure that all developers are working from the same set of codes Component Build Service (CBS) which hosts all Java archives needed or produced during software development and Software Logistics (SL) which is concerned in deploying the application in different systems and makes it available in all the stages of the product cycles and other transport and maintenance functions. JDI will make further reductions in development time and costs, fixing bugs easily and increasing reliability for processes throughout the application life cycle. JAVA Development Infrastructure (JDI) is a new feature in SAP NetWeaver Web Dynpro is built on it and JDI will connect Integrated Development Environment (IDE) to infrastructure. In the Web Dynpro, User Interface will be dynamic from Client and server side but in the ABAP/Dynpro it will be dynamic from server-side only. Web Dynpro supports reusing of components while in the Dynpro component reusing is very limited since the screen and the program are coupled (dealing with them as one object). Also, the UI utilizes client-side dynamics, personalizes the browser and is 508-accessibility compliant. In the Web Dynpro the screen updates without page reloads. Since Web Dynpro is built on top of the SAP Web AS it offers the same support for multi-user development and software logistics that currently exist in R/3. This means that many efforts for maintaining, and running different Web servers, UI servers, and client GUI installations which are the case in ABAP/Dynpro will simply go away. Administration of Web Dynpro does not mean anything more than administration of the SAP Web Application Server and its also browser-based clients (zero footprint for UI). The Dynpro is divided into two parts: layout & flow logic, while the Web Dynpro is roughly divided into three layers, each of which can be developed and modified independently:ĪBAP/Dynpro cannot really support a modern separation of front-end/presentation and backend/business logic in fact they are working together as one object. Web Dynpro depends on the Model-View-Controller (MVC) principle. SAP NetWeaver’04 will only support Web Dynpro development in Java but future releases of SAP NetWeaver will give the developer alternatives either to program by Java or ABAP language. Web Dynpro programming model is fully independent of the ABAP language while the Dynpro is fully ABAP language and not Object Oriented Programming (OOP). Most of Web Dynpro development is really programming language independent, requires few skills, and provides much higher productivity in UI design.
