Application View Control: Accessing an Enterprise Application from a Web Service

Note: The Application View control uses Application Views defined using the Application Integration (AI) component of WebLogic Integration. The Application View control is available in WebLogic Workshop only if you are licensed to use WebLogic Integration's AI component.

Note: In this release, the Application View control is supported only in the sample workshop domain. In future versions, support will be provided for enabling the Application View control in other domains.

The Application View control allows your service to access an enterprise application using an Application View. An Application Views must be created using WebLogic Integration's Application Integration (AI) component before it can be referenced using an Application View control. To learn more about application views and their relationship to enterprise applications, see Overview: Adapters and Application Views.

Like other WebLogic Workshop controls, the Application View control allows WebLogic Workshop web services to interact with enterprise applications using simple Java APIs. They allow a web service developer to access an enterprise application even if they don't know any of the details of the application's implementation.

The Application View control provides a means for a web service developer to invoke Application View services both synchronously and asynchronously, and to subscribe to Application View events. In both the service and event cases, the developer uses simple Java APIs. The developer need not understand XML, or the particular protocol or client API for the enterprise application (hereafter referred to as an Enterprise Information System or EIS).

# WebLogic Workshop Is Not Intended for Application View Development

The Weblogic Workshop Application View control is designed to make it easy for you to use an existing, deployed Application View from within your web services. WebLogic Workshop is specifically not designed to help you develop and deploy Application Views. Please consult the WebLogic Integration documentation to learn how to create and deploy Application Views.
