Setting Up the Web Dynpro Development Component (DC) 

In order to develop Web Dynpro for Java applications, you first need a suitable development component – either local or integrated in the NWDI - in the Developer Studio. At design time, this kind of development component serves as a container for all Web Dynpro-specific entities and other resources. You can create all DC types in the Developer Studio using the Wizard tool. As a result, you have a well-defined project framework with an initial structure for the DC type concerned. This structure, in turn, serves as the starting point for defining further application-specific resources.

When setting up development components, you should keep the following distinctions in mind:

Implementing Web Dynpro DCs

In general, you will be involved in real development tasks that will require you to split up the work into several projects. These projects also have clearly defined dependencies. The development tasks are split up among several developers or even several development teams that may also be spread out over different locations. Here, the development process must support both the creation of reusable software units and the development within the team in an optimum manner.

It is precisely here where the NW Development Infrastructure (NWDI) is put to use. With its development components (DCs), it provides a powerful base for component-based development, an infrastructure that enables you to reduce overall development time, and a consistent environment for the entire software life cycle.

In the Developer Studio, you work with projects, as before. In this case, you work with so-called Web Dynpro DC projects.

Structuring Web Dynpro DCs into Working Sets

You can structure your Web Dynpro DCs using Working Sets. This is independent from the physical storage in the Development Infrastructure or Local Development folders.

...

       1.      To structure your Web Dynpro DCs, choose Menu  in the Web Dynpro Explorer followed by Select Working Set.

       2.      Configure the Working Sets to your needs.

       3.      Select Menu again and choose Top Level Elements → Working Sets to display the defined structure.

Converting Existing Web Dynpro Projects

The use of local Web Dynpro projects is deprecated, use Web Dynpro DC instead.

...

       1.      Open the context menu of the Web Dynpro project.

       2.      Choose  Development component → Convert Project to Development Component.

Sharing Local Web Dynpro DCs in the NWDI

For various reasons, it can happen that you have already implemented a function using local Web Dynpro DCs and would like to fully integrate these into the NWDI. In such a case, you can use the migration function, where the existing projects units are passed to one or even several Web Dynpro DCs.
