Creating New Development Objects

This procedure shows you how to create a new development object for a composite application layer. You need to follow the same general sequence to create development objects for almost all the composite application layers.

Prerequisites

You have created your own product (composite application) with the corresponding software component(s).

Make sure you have created all necessary development components, either during the initial product (composite application) generation or later on using the context menus of each layer. You cannot create a development object without a corresponding development component.

For more information about creating development components, see Creating Development Components.

Note Note

Note that Guided Procedures development objects can only be imported without the option of modifying them with the Composite Designer perspective.

End of the note.

Procedure

In the Composite Explorer view, expand the layers of your composite application.

Note
When you create your development components from the context menus (of each composite layer), you are prompted to switch to a new perspective that is specific for the selected technology. To launch the standard technology specific perspective, choose Yes.

Alternatively, you continue working in the Composite Explorer view of the Composite Designer perspective.

End of the note.
To create a new development object, select it from the Composite Designer Palette and point to the corresponding layer of your product, then drop it using the primary mouse button (you can also drag and drop it).
Continue developing your object following the corresponding toolset documentation:

Note
Keep in mind that the descriptions below are for the corresponding toolsets and minor differences can be observed if you start the from the wizards from Composite Designer. However, the content is the same.

  - CAF Application Service

  - CAF Business Object
    For more information, see Creating Business Objects.
    
    Note
    Keep in mind that you need to generate the CAF projects first before you continue building your composite application (product).
    
    Additionally, if you expose the CAF application services and business objects as Web services later on, a new icon will be displayed indicating this action without removing their original CAF icons.

Note Note

To facilitate your work, the Composite Designer represents the Search Console and the predefined templates for application generation.

You use the Search Console to include already existing services as external services in your own applications. For more information, see Browsing Services in Search Console.

You can drag and drop the external services found with the Search Console directly in the overview of the Composite Designer layers and the corresponding wizards will be started. If you drag and drop the services in the External Services layer, you need to specify the detailed composite application layer in which you intend to use this external service.

In addition, with Composite Designer you can automatically generate parts of applications using predefined templates. For more information, see Generating Applications Based On Predefined Templates.
