11.2.2.1.5 Web Dynpro Perspective
Web Dynpro perspective provides various tools that are required for using the Web Dynpro tech-
nology for generating user interfaces of the browser-based applications. It supports developers
during the entire development cycle of Web Dynpro applications starting with generating project
components, implementing controllers and professional presentation interfaces, and deploying
and testing of the finished application. All of the development objects are generated declaratively
using wizards or graphical tools that entail minimal manual programming.
Per the MVC design pattern, persistent data are provided in the Web Dynpro by a model
layer of the entire application. There are relevant model types for the various back-end scenarios.
Web Dynpro provides powerful wizards and generation tools to ensure that the back-end logic is
integrated seamlessly.
Web Dynpro perspective addresses the following tasks:
◾
Create Web Dynpro projects with or without a connection to the SAP component model.
◾
Design the application using the declarative and graphical facilities of the Data and
Application Modelers, for example, displaying relationships between the components of the
Web Dynpro project, creating views and view sets, and defining the view sequence using the
navigation links.
◾
Create reusable Web Dynpro application components.
◾
Design the view layout with the graphical View Designer.
◾
Define view contexts to store local view controller data and its references (to model data,
dictionary types, or to other view contexts).
◾
Integrate a Java Dictionary to define user-defined global data types like simple and struc-
tured data types as well as user-interface-specific texts and messages.
◾
Import model descriptions to achieve back-end connection.
11.2.2.1.6 Web Service Perspective
Web Service perspective provides various tools that are required for defining Web Service provid-
ers or for using Web Service clients. It consists of EJB Explorer, Java Explorer, Client Explorer,
Web Service Navigator, and an integrated environment for testing Web Services.
EJB and Java explorers organize all Web Service endpoints and related objects like virtual inter-
faces, Web Service definitions, and deployment descriptors. Client Explorer generates client proxies
corresponding to a Web Service as well as the relevant deployable or stand-alone proxy projects.
Web Service perspective addresses the following tasks:
◾
Create Web Services as endpoints for Session Beans and Java classes.
◾
Deploy Web Services on the J2EE Server.
◾
Integrate UDDI publishing and test environment.
◾
Integrate UDDI client browser.
◾
Web Service client proxies.
11.2.2.2 NWDS Development Process
The development environment has been configured first so that it can use the JDI by importing a
predefined
development configuration
from the SLD into NWDS. The development configuration
enables the local development environment to access the relevant infrastructure services.
