This chapter describes the administrative tasks you can perform and the tools you can use to deploy, manage, monitor, and configure applications developed for the Oracle Application Development Framework (Oracle ADF).
This chapter includes the following sections:
The Oracle Application Development Framework (Oracle ADF) builds on Java Platform, Enterprise Edition (Java EE) standards and open-source technologies to provide a complete framework for implementing service-oriented applications. You can use this framework to provide enterprise solutions across different platforms. You can build applications that search, display, create, modify, and validate data for web, web services, desktop, or mobile interfaces.
You use Oracle JDeveloper 11g with Oracle ADF to develop applications with an environment that supports the full development lifecycle of design, test, and deployment. For more information about ADF development, see the Oracle Fusion Middleware Fusion Developer's Guide for Oracle Application Development Framework.
After you have developed and tested your ADF application in test environments, you can deploy your application to production environments using the tools described in this book. You can monitor the performance of applications as they are running. You can also manage and configure properties and attributes.
Oracle ADF supports the industry-standard model-view-controller architecture to achieve separation of business logic, navigation, and user interface. The MVC architecture provides:
A model layer that represents the data values
A view layer that contains the UI components
A controller layer that handles input and navigation
A business service layer that encapsulates business logic
The Fusion web application technology stack components are:
ADF Model, for accessing declarative data binding metadata
ADF Business Components, for building business services
ADF Faces rich client, for AJAX-enabled UI components for web applications built with JavaServer Faces (JSF)
ADF Controller, for input processing, navigation, and reusable task flows
ADF Business Components are application objects you can use to implement service-oriented Java EE applications. You implement ADF Business Components for clients to query, insert, update, and delete business data. You can apply business rules to the Business Components to enforce proper usage. The key components of ADF Business Components are the entity object, the view object, and the application module.
An entity object represents a row in a database table. It uses data manipulation language (DML) operations to modify data. Entity objects are used with others to reflect relationships in the database schema.
A view object represents a SQL query. You use the SQL Language to query the database to obtain the results. You can also link a view object with other entity objects to create master-detail hierarchies.
An application module is the transactional component that allows UI components to access data. It presents a data model and methods to perform certain tasks.
ADF Model implements a service abstraction called data control. Data control uses metadata interfaces to abstract business services. This metadata is used to describe data collections, properties, methods, and types. In JDeveloper, data controls appear in the Data Controls panel. When you drag and drop attributes, collections, and methods onto a page, JDeveloper automatically creates the bindings from the page to the associated services.
ADF Controller provides a navigation and state management model that works with JSF. You can create navigational flows called task flows that encapsulate a specific task sequence.
ADF Faces has a large set of components, including tables, trees, dialogs, accordions, and a variety of layout components. It also includes ADF Data Visualization components, which are Flash- and SVG-enabled, for displaying graphs, charts, and gauges.
You can perform a variety of administration tasks on ADF applications. You can deploy ADF applications using Enterprise Manager Fusion Middleware Control, WLST commands, the
ojdeploy command, scripts, or the WebLogic Administration Console.
After the ADF application has been deployed, you can configure application properties using Enterprise Manager Fusion Middleware Control. You can also configure some properties using the MBean Browser to change values in the ADF MBeans. For example, you can use Enterprise Manager Fusion Middleware Control to change the URL connection or WebService connection endpoints or seed the production credentials.
When you run the application, you can monitor performance data on the application modules, application module pooling, and task flows.
