Web
Dynpro Application: Configuration, Deployment and Execution
Purpose
A Web Dynpro application represents the point of entry to the functions provided by a Web Dynpro component. The Web Dynpro application is identified by a URL. This URL is then called by a client (such as an Internet browser) to trigger the execution of the application on the server.
The point of entry defined by a Web Dynpro application consists of:
- the component called (the root component)
- the interface view of the window of the root component, and
- the inbound plug of this interface view. This inbound plug must be of the type Startup.
Starting an Application
When a user calls the URL of a Web Dynpro application, the system generates and initializes an instance of the root component. Then the inbound plug of the interface view is called. When you call an application, you can use the event handler of the inbound plug to pass parameters. These parameters are defined as URL parameters.
Exiting an Application
To end a Web Dynpro application from within the application itself, the system must call the outbound plug of the interface view of the root component. The outbound plug must be of the type Exit Plug.
By default, the user is then routed to the page defined in logoff.htm. For the outbound plug, you can define a different page to which the user is directed using the parameter Url.
Configuring an Application
You can use predefined properties or define your own properties to configure a Web Dynpro application.
In addition, there are several services to help you with the configuration, such as the configuration service or the user management service.
See Configuring a Web Dynpro Application.
Deploying an Application
This section describes the steps you must perform to deploy a Web Dynpro application on the J2EE server.
See Deploying a Web Dynpro Application.
Executing an Application
This section provides information about the different clients on which you can execute a Web Dynpro application, and about the specific parameters you can use to call a Web Dynpro application.
