Package com.sap.tc.webdynpro.services.sal.api Description

The com.sap.tc.webdynpro.services.sal.api package contains base interfaces for application visible services and service factories. Besides that, some Exception types are defined here.

The com.sap.tc.webdynpro.services.sal package defines the server abstraction layer (shortly, SAL). The server abstraction layer consists of a set of services for

• application deployment
• user management
• URL generation
• internationalization
• configuration
• runtime repository

In general, a service is defined by two sets of interfaces: an interface that is visible for the application and an interface that is visisble for the Web Dynpro framework. A common pattern is used to access a service interface: For each service interface, there is a corresponding service factory interface that defines methods to create instances of the service. Since there are multiple server platform implementations supported by Web Dynpro (e.g. running on top of the Portal Runtime, or running as J2EE servlet), ServiceManager classes are used to instantiate the concrete servic factory implementation. The concrete server platform implementation is specified by the configuration and is known to the ServiceManager classes.
