Defining Dependencies Between Components

Use

Development Components (DC) are packages of business and UI functionality. Components can use one another and, therefore, depend on one another. A component can depend on any number of components, and a number of components can depend on one single component. Dependencies between DCs are not static and may change over time. A component may declare new dependencies or delete existing ones.

There are some restrictions on the types of valid dependencies that can be defined. The set of permitted DC dependencies is limited by DC types. When you use the standard Dependencies tab in the Component Properties view, only acceptable DCs are displayed.

Prerequisites

You have created more than one Development Component related to the Mobile Applications perspective.

Procedure

1. In the Development Infrastructure perspective of SAP NetWeaver Developer Studio, select the development component, whose dependencies you want to manage.

2. In the Component Properties view, choose the Dependencies tab page.

3. To declare dependency to another DC, choose the Add button.

   The following table outlines the matrix of DC type dependencies that you can use.

   To DC type	Mobile Java Component	Mobile Service Components	Mobile UI Components for Handhelds	Mobile Application
   From DC type
   Mobile Java Component	yes	yes	yes	no
   Mobile Service Components	yes	yes	no	no
   Mobile UI Components for Handhelds	yes	yes	yes	no
   Mobile Application	yes	yes	yes	no

4. In the Adding Dependencies dialog, select the component to which you want to add a dependency.

5. Choose Next .

6. Select the DC from the list and choose Finish. The DC appears in the list of DCs required for this DC

Result

You have defined the dependencies to other DCs. Now you can reuse the functionality of the dependent component.
