Composing Services

Using the SAP NetWeaver Developer Studio, you can easily work with composite applications. Installed with the usage type CE-APPS are two options for composing applications, as well as the Service Interface Editor and data mapping functionality:

• Composing Services with Service Composer

  Allows you to perform service composition using the Service Composer perspective of the Developer Studio.

• Composing Services with CAF

  You can still use the Composite Application Framework (CAF) perspective of the Developers Studio, which is well-known from previous releases . Note that the CAF composition toolset is integrated and its functionality can be used from the Service Composer perspective of the Developer Studio.

• Modeling Services with the Service Interface Editor

  You can use the Service Interface Editor (SIE) to model and manage local WSDL and XSD files in a convenient and simple manner. The SIE avoids the complexity of customizing a back-end service by the standard interface editors and does not require profound web service development knowledge. If you are an advanced user, you can edit the WSDL source code.

• Working with Data Mappings

  You can use data mappings to define how the source context data is transformed to the target context data. The SAP NetWeaver Developer Studio provides a mapping and expression editor where you define these transformations and create expressions over the context data.

You need to configure your Composite Application Framework and Service Composer:
