In this tutorial, you learn how to create JSF pages using Oracle ADF Faces Rich Client Components. Oracle ADF Faces Rich Client is a set of standard JSF components that include built-in interactive functionality provided by Ajax and other UI technologies. While Ajax allows rich client-like applications to run on standard internet technologies, JSF provides server-side control, which reduces the dependency on an abundance of JavaScript often found in typical Ajax applications.

The page you build in this tutorial displays the content of a shopping cart on one side and lists all the available products on the other side. Another pane displays the product details. You implement drag and drop functionality enabling users to fill their shopping cart by moving a selected product in the shopping cart area. You also create data visualization components, accordions and add a popup window.

Step 1: Creating a Page Template

In this section you open the starter application and create a page template to be used for additional pages you will create: To create the page template perform the following steps:

Page templates let you define entire page layouts, including values for certain attributes of the page. Show more or lessRead more...

When pages are created using a template, they inherit the defined layout of a template. When you make layout modifications to the template, all pages that consume the template will automatically reflect the layout changes. You can either create the layout of the template yourself, or you can use one of the many quick layout designs. These predefined layouts automatically insert and configure the correct components required to implement the layout look and behavior you want. For example, you may want one column's width to be locked, while another column stretches to fill available browser space.

To use page templates in an application, you first create a page template definition. In contrast to regular JSF pages where all components on the page must be enclosed within the f:view tag, page template definitions cannot contain an f:view tag and must have pageTemplateDef as the root tag. The page that uses the template must contain the document tag, (by default, JDeveloper adds the document tag to the consuming page).

A page template can have fixed content areas and dynamic content areas. For example, if a Help button should always be located at the top right-hand corner of pages, you could define such a button in the template layout, and when page authors use the template to build their pages, they do not have to add and configure a Help button. Dynamic content areas, on the other hand, are areas of the template where page authors can add content within defined facets of the template or set property values that are specific to the type of pages they are building. The entire description of a page template is defined within the pageTemplateDef tag, which has two sections.

One section is within the xmlContent tag, which contains all the page template component metadata that describes the template's supported content areas (defined by facets), and available properties (defined as attributes). The second section (anything outside of the xmlContent tag) is where all the components that make up the actual page layout of the template are defined. The components in the layout section provide a JSF component subtree that is used to render the contents of the page template.

Step 2: Designing a Page using a Page Template

Now that the template has been created you can create a new page and use the template as the default structure for the page. To do this, perform the following steps:

You can use page templates to build JSF pages or page fragments. Show more or lessRead more...

If you modify the layout section of a page template later, all pages or page fragments that use the template are automatically updated with the layout changes.

Typically, you create JSF pages in the same project where page template definitions are created and stored. If the page templates are not in the same project as where you are going to create template-based pages, first deploy the page templates project to an ADF Library JAR. In the page that consumes the template, you can add content before and after the pageTemplate tag, but you will typically add elements within the defined facets of the template. As a best practice, you should use only one pageTemplate tag in a page.

JDeveloper simplifies the creation of JSF pages based on page templates by providing a template selection option in the Create JSF Page or Create JSF Page Fragment wizard.
  1. Right-click the ViewController project and select New > Page...

    invoking the New gallery from application navigator
  2. In the Create JSF Page dialog, change the file name to products.jsf and ensure the Document Type is set to Facelets. Select the Reference ADF Page Template radio button and choose the Storetemplate template. Click OK.

  3. specifying the definition of the page, including using a template

  4. The products.jsf appears as a new node in the Applications window and opens in the Editor using the storetemplate.jsf template.

  5. page diaplyed in design view

    If the page doesn't render visually in the design editor and instead looks like a series of nested boxes, close the workspace and reopen it.

  6. From the Components window, expand the Layout category, and drag and drop a Panel Splitter component onto the center facet.

    adding panelsplitter to center facet

    In addition to the Panel Splitter, ADF Faces provides a number of other layout components that can be used to arrange other components on a page. Show more or lessRead more...

    Usually, you begin building your page with layout components. You then add components that provide other functionality (for example rendering data as tables or forms) either inside facets or as child components to these layout components. In addition to layout components that simply act as containers, ADF Faces also provides interactive layout components that can display or hide their content, or that provide sections, lists, or empty space. Layout components also provide geometry management functionality, such as stretching their contents to fit the browser windows as the window is resized, or the capability to be stretched when placed inside a component that stretches. Some layout type and components are listed below.

    Page Layout Containers
    - panelStretchLayout: Contains top, bottom, start, center, and end facets where you can place other components.
    - panelSplitter: Divides a region into two parts (first facet and second facet) with a repositionable divider between the two. You can place other components within the facets.
    - panelDashboard: Provides a columnar display of child components (usually panelBox components).
    - panelGridLayout: Uses one or more child gridRow components to define height and margins in a grid layout structure. Each gridRow component uses child gridCell components to define width, column span, margins, and more for the columns of a grid layout.
    - panelFormLayout: Positions input form controls, such as inputText components, so that their labels and fields line up vertically. It supports multiple columns and contains a footer facet.

    Components with Show/Hide Capabilities
    - showDetailHeader: Can hide or display contents below the header. Often used as a child to the panelHeader component.
    - showDetailItem: Used to hold the content for the different panes of the panelAccordion or different tabs of the panelTabbed component.
    - panelBox: Titled box that can contain child components. Has a toolbar facet.
    - panelAccordion: Used in conjunction with showDetailItem components to display as a panel that can be expanded or collapsed.
    - panelTabbed: Used in conjunction with showDetailItem components to display as a set of tabbed panels.
  7. Drag and drop a Panel Accordion layout component onto the first facet on the left hand side of the panel splitter.

    inserting a panel accordion in first facet

    A Panel Accordion component is added to the facet, and a nested Show Detail Item is also created, to hold content for the first pane of the accordion.

  8. In the create panel Accordion dialog, set the text value to MyCart.

Step 3: Using Input and Output Components

The page layout is complete, now it's time to add some data. The first step in this process it to create data controls from the Products POJO (Plain Old Java Object). To do this, perform the following steps:

Once you have your application's services in place, you can use JDeveloper to create data controls that provide the information needed to declaratively bind UI components to those services. Show more or lessRead more...

In a Java EE application, you normally create JPA entities that represent tables in a database and then create a session facade over all the entities. The facade provides a unified interface to the underlying entities. Using Oracle ADF model, you can create a data control for a session bean, and that data control will contain representation of all the JPA entities under the session bean. ADF Data Controls consist of one or more XML metadata files that define the capabilities of the services that the bindings can work with at runtime. The data controls work in conjunction with the underlying service implementations without changing the implementation of the service. You can also create Data Controls from simple POJOs. For applications built using ADF Business Components as the service implementation, the data control is implicitly defined by the Application Module data model. This tutorial uses a data control based on a simple POJO to prevent the need for a database connection.

  1. From an existing POJO Class, create the data control using the ADF Data Binding facility.
    In the Applications window, expand the Model project. Expand the Application Sources and model nodes. Right-click and select Create Data Control from the context menu.

    creating data control from pojo

  2. In the first page of the Bean Data Control dialog, change the name of the data control to StoreProducts and click Next.

    defining data control name

  3. In the Choose ADF Data Control Features page, select the Transactions and Custom CRUD features and click Finish.

    specifying ADF data control features

  4. The DataControls.dcx file is created and will open in the editor. You could define UI hints and validation at this layer, but you will accept the defaults here and continue on creating the user interface.

    datacontrols.dcx filer

  5. Click the products.jsf tab to bring it to the foreground of the editor.

  6. In the Applications window, expand the Data Controls  accordion and expand the StoreProducts node. You may need to click the refresh icon in the Data Controls panel to enable the StoreProducts node.

    viewing the data controls

  7. Drag and drop the products collection of the StoreProducts data control onto the center area of the af:panelCollection in the design editor. From the popup menu, select ADF Table...

  8. Structured data can be displayed as tables consisting of rows and columns using the ADF Faces table component. Show more or lessRead more...

    The table component uses a CollectionModel class to access the data in the underlying collection. This class extends the JSF DataModel class and adds on support for row keys and sorting. In the DataModel class, rows are identified entirely by index. This can cause problems when the underlying data changes from one request to the next, for example a user request to delete one row may delete a different row when another user adds a row.

    To work around this, the CollectionModel class is based on row keys instead of indexes. The immediate children of a table component must be column components. Each visible column component is displayed as a separate column in the table. Column components contain components used to display content, images, or provide further functionality.

    The child components of each column display the data for each row in that column. The column does not create child components per row; instead, the table uses stamping to render each row. Each child is stamped once per row, repeatedly for all the rows. As each row is stamped, the data for the current row is copied into a property that can be addressed using an EL expression. You specify the name to use for this property using the var property on the table. Once the table has completed rendering, this property is removed or reverted back to its previous value.

    adding a read only table to the page

  9. In the Create Table dialog, select the Row Selection (Single Row) option and click the Enable Sorting and Read-Only Table options.
    Then click OK.

    edit table columns dialog window

  10. In the Structure window, select the af:table component and in the Properties window, expand the Behavior node. Set the EdtingMode property to clickToEdit. In the Appearance node, set the ColumnStretching property to last.

    To quickly locate a property by name, type the property name in the search field at the top of the Properties window.

  13. In the Create Form dialog, select the Submit checkbox to include a control for a submit action.

    edit form fields dialog

    Click OK.

  14. Now add an ADF List View component. The ListView component uses to access the data in the underlying list. You may also use other model instances, e.g., java.util.List, array, and javax.faces.model.DataModel and the listView will automatically convert the instance into a CollectionModel.

    Expand the Recommendations accordion pane in the design view. Drag and drop the products node from the data controls window to the recommendations accordion in the design view. In the popup menu, select Table/List View > ADF List View...

    Click Finish.

  19. Save your work.

  20. Data from the products data control is being displayed on this page in three different binding styles. To ensure that all rows are available so that all three bindings are kept in sync, modify the products iterator range size. Select the Bindings tab for the products.jsf page. In the Executables section, select productsIterator.

    setting list item data

  21. In the Properties window, set the RangeSize property to -1.

    setting list item data

  22. Save all your work and right-click the page and choose Run to re-deploy and re-run the page.
    The page should display the product data in the Recommendations accordion, table, and form as shown:

  24. Experiment with column resizing in the table using the shortdesc column. Click the Detach menu option to isolate the content of the panel in the browser.

    detaching the table

    Click the Detach option again to return to the original display.

  25. Explore the View menu option and hide some of the columns.

    hide some columns

    The columns will remain hidden until you redisplay them. The number of hidden columns is displayed in a message below the table. Column reordering and resizing are features of the ADF Faces table component, while the View menu and it's capabilities and the Detach button are part of the Panel Collection component.

  26. In the next few steps you add some images and graphical items to the page.
    In the Product Details tab, right-click the cost inputText item in the form and select Convert To... from the context menu.

  27. There are a variety of ways to make analyzing data easier for end users by using graphical components. Show more or lessRead more...

    The slider components present the user with a slider with one or two markers whose position on the slider corresponds to a value. The slider values are displayed and include a minus icon at one end and a plus icon at the other. The user selects the marker and moves it along the slider to select a value. The inputNumberSlider component has one marker and allows the user to select one value from the slider.

    To display an image on a page, you use the image component and set the source attribute to the URI where the file is located. The image component also supports accessibility by providing a way to link to a description of the image. The image component can also be used as a link and can include an image map, if placed inside a goLink component.

    The richTextEditor component provides rich text input that can span many lines and can be formatted using different fonts, sizes, justification, and other editing features that may be required when you want users to enter more than simple text. For example, the richTextEditor might be used in a web-based discussion forum, allowing users to format the text that they intend to publish.

  37. Experiment moving the rating slider, the cost spinbox, and using the rich text editor. Notice that selecting any of the rows in the product table automatically changes the row currency in the Product Details tab. This is handled by the ADF Data Binding layer.

Step 4: Working with Behavior Components

Behavior components are those that provide operational functionality to an application. In this section you will create menus, popup and printable pages and allow users to drag and drop products into a shopping cart area. To implement this type of functionality, perform the following steps:

The ADF Faces framework provides the ability to drag and drop items from one place to another on a page at runtime. Show more or lessRead more...

In most cases, drag and drop at runtime can easily be implemented by adding the appropriate tags to the source and target and implementing code in a managed bean. Drag and drop provides users with an interactive experience that is expected in rich web applications. For example, in a file explorer application, users would expect to be able to drag files from one directory folder to another.

If drag and drop behavior is implemented in an ADF Faces Rich Client application, when users click on an item and begin to drag, the browser displays the element being dragged as a ghost element attached to the mouse pointer. Once the ghost element hovers over a valid target, the target component shows some feedback (for example, it becomes highlighted). If the user drags the ghost element over an invalid target, the cursor changes to indicate that the target is not valid.

When dragging attribute values, the user can only copy the value to the target. For all other drag and drop scenarios, on the drop, the element can be copied (copy and paste), moved (cut and paste), or linked.
  1. To implement menus in your application, add a menu to the panel collection for the table. In the design editor of the products.jsf page, right-click within the menu facet in the panel collection and select Insert inside Facets menus - Menu from the context menu.

    Opening file name pane with open or save as options

    Select Open with to view the table in Excel (assuming you have Excel installed) and click OK.

    Verify the table is exported and close Excel if you wish.

  13. Now create a popup window in the products.jsf page. In the Structure window, select the topmost af:form component.

    highest-level form component selected in structure/

  14. In the Components window, expand the Layout category and locate the Secondary Windows section. Drag the Popup  component onto the form component in the Structure window. The design view will change to allow visual editing of the popup.

  15. You can use the popup component with a number of other ADF Faces components to create a variety of dialogs, menus, and windows that provide information or request input from end users. Show more or lessRead more...

    Using these components, you can configure functionality to allow your end users to show and hide information in secondary windows, input additional data, or invoke other functionality. The capabilities offered by these components allow you to render content or functionality that is supplemental to the content rendered on the primary interface and, as a result, develop uncluttered and user friendly interfaces.

    The popup component is an invisible layout control, used in conjunction with other components to display inline (that is, belonging to the same page) dialogs, windows, and menus. The popup component is invoked from within the primary interface and the application manages the content that renders in the popup component like content in the primary interface without interference from popup blockers. It is recommended that the content type you render in a popup component be HTML. Other types of content, such as Flash or PDF files, may not render appropriately in a popup component.

  31. In the next couple of steps, add a popup page to show products using a carousel.

    You can display images in a revolving carousel. Show more or lessRead more...

    Users can view a series of images, one for each record. They can change the image at the front either by using the slider at the bottom or by clicking one of the auxiliary images to bring that specific image to the front.

    By default, the carousel displays horizontally. The objects within the horizontal orientation of the carousel are vertically-aligned to the middle and the carousel itself is horizontally-aligned to the center of its container.

    You can configure the carousel so that it can be displayed vertically, as you might want for a reference "rolodex". By default, the objects within the vertical orientation of the carousel are horizontally-aligned to the center and the carousel itself is vertically aligned middle. You can change the alignment using the carousel's alignment attributes.

Step 5: Working with ADF Data Visualization Components

Now add a gauge to display the rating of any particular product. To create this gauge, perform the following steps:

The ADF data visualization components provide significant graphical and tabular capabilities for displaying and analyzing data. Show more or lessRead more...

These data visualization components provide the following common features:
- They are full ADF Faces components that support the use of ADF data controls.
- They provide for declarative design time creation using the Data Controls Panel, the JSF visual editor, Properties window, and Components window.
Each component offers live data preview during design. This feature is especially useful to let you see the effect of your design as it progresses without having to compile and run a page. Data visualization components include: graphs, gauges, pivot tables, maps, Gantt charts, hierarchy viewer, sunburst, and treemap. The prefix dvt: is used to denote the data visualization components.

The gauge component renders graphical representations of data. Unlike the graph, a gauge focuses on a single data point and examines that point relative to minimum, maximum, and threshold indicators to identify value thresholds. One gauge component can create a single gauge or a set of gauges depending on the data provided. The following kinds of gauges can be produced by this component:

Dial gauge: Creates a gauge that indicates its metric value along an 180-degree arc. This type of gauge usually has an indicator in the shape of a line or an arrow that points to the value that the gauge is plotting.
Status meter gauge: Creates a gauge that indicates the progress of a task or the level of some measurement along a horizontal rectangular bar. An inner rectangle shows the current level of a measurement against the ranges marked on an outer rectangle.
Status meter gauge (vertical): Creates a gauge that indicates the progress of a task of the level of some measurement along a vertical rectangular bar
LED (lighted electronic display) gauge: Creates a gauge that depicts graphically a measurement, such as key performance indicator (KPI). Several styles of graphics are available for LED gauges such as arrows that indicate good (up arrow), fair (left- or right-pointing arrow), or poor (down arrow).

You can specify any number of thresholds for a gauge. However, some LED gauges (such as those with arrow or triangle indicators) support a limited number of thresholds because there are a limited number of meaningful directions for them to point. For arrow or triangle indicators, the threshold limit is three.

  1. In the design view of the products.jsf page, click the Rating tab.

    the rating tab is highlighted
  2. In the data controls window, expand StoreProducts and products and drag the rating attribute onto the rating tab of the design editor. Choose Gauge... from the popup menu.

    drag gauge onto rating tab

  3. In the Component Gallery dialog, select the Status Meter Gauge category, then Circular Status Meter  as the meter type.

    dial with thresholds component selected

    Click OK.

  4. In the Create Circular Status Meter Gauge dialog, set the Maximum Value field to 10.
    Click the green plus sign and add three threshold attributes. Name and set them using the values below. Set the colors to ones generally like those in the image.

    Set the lowest threshold (threshold1) to 1.
    Set the middle threshold (threshold2) to 5.
    Leave the highest threshold (threshold3) at Maximum.

  5. threshold max value set to 5

    Click OK.

  6. Save your work and refresh the page in the browser. The status meter displays the current rating value for the current (first) product.

  8. Click Submit and then click the Rating tab to see the new value reflected in the table as well as the gauge. An error is raised referencing PPR. You will correct this in the next step.

Step 6: Implementing Partial Page Rendering

The goal of Partial Page Rendering is to improve a web page's interactivity, speed, and usability. Show more or lessRead more...

Ajax (Asynchronous JavaScript and XML) is a web development technique for creating interactive web applications, where web pages appear more responsive by exchanging small amounts of data with the server behind the scenes, without the whole web page being rerendered.

With ADF Faces, the feature that delivers the Ajax partial page render behavior is called partial page rendering (PPR). PPR allows certain components on a page to be rerendered without the need to rerender the entire page. For example, an output component can display what a user has selected or entered in an input component, without the whole page rerendering. In order for PPR to work, boundaries must be set on the page that allow the lifecycle to run just on components within the boundary. In order to determine the boundary, the framework must be notified of the root component to process. The root component can be identified in two ways:

- Events: Certain events indicate a component as a root. For example, the disclosure event sent when expanding or collapsing a showDetail component indicates that the showDetail component is a root. When the showDetail component is expanded or collapsed, only that component goes through the lifecycle. Other examples of events identifying a root component are the disclosure event when expanding nodes on a tree, or the sort event on a table.

- Components: Certain components are recognized as a boundary, and therefore a root component. For example, the framework knows a popup dialog is a boundary. No matter what event is triggered inside a dialog, the lifecycle does not run on components outside the dialog. It runs only in the popup.

In addition to built-in PPR functionality, you can configure components to use cross-component rendering, which allows you to set up dependencies so that one component acts as a trigger and another as the listener. When an event occurs on the trigger component, the lifecycle is run only on listener components and child components to the listener, and only the listener components and their children are rerendered. Cross-component rendering can be implemented declaratively. However, by default, all events from a trigger component will cause PPR (note that some components, such as table, trigger partial targets on only a subset of their events). For these cases where you need strict control over the event that launches PPR, or for cases where you want to use some logic to determine the target, you can implement PPR programmatically.
  1. In order to refresh the gauge when the when you select a row in the table, you need to define Partial Page Rendering behavior explicitly. To do so, perform the following steps:

    In JDeveloper, select the rating status meter component in the design view. In the Properties window, expand the Behavior category. Click the Property menu icon for the PartialTriggers property and select Edit.

    edit menu highlighted in the partial triggers property
  2. In the Edit Property dialog, expand the document, form, pageTemplate, facet (center), panelSplitter - ps1, facet (second), panelSplitter - ps2, facet (first), and panelCollection components. Select the table* - t1 component, and shuttle it to the Selected pane. This defines what will trigger the refresh of the gauge.

    Click OK.

  3. Save all your work and reload the page in the browser. Click the ratings tab to and select different rows in the table to refresh the gauge.

Step 7: Using Skins to Change the Look and Feel of an Application

You can customize the appearance of ADF Faces and ADF Data Visualization components. Show more or lessRead more...

You can apply an ADF skin to the application or by applying CSS style properties directly to an ADF Faces or ADF DVT component if the component exposes a style-related property (styleClass or inlineStyle). Choosing the latter option means that you override style properties defined in your application's ADF skin for the component. You might do this when you want to change the style for an instance of a component on a page rather than for all components throughout the application or you want to programmatically set styles conditionally. For example, you want to display text in red only under certain conditions. In all other cases, styleClass or skinning should be used.

An ADF skin is a type of CSS file where you define CSS style properties based on the Cascading Style Sheet (CSS) specification for the component for which you want to customize the appearance. The ADF skin defines rules that determine how to apply CSS style properties to specific components or groups of components. The end user's browser interprets these rules and overrides the browser's default settings. See the Skin Editor documentation for further information:
  1. Finally in this section you'll see how to change the look and feel of the whole application using a different skin. To implement this functionality, perform the following steps:

    In the Applications window, expand the Web Content - WEB-INF node and double-click the trinidad-config.xml file to open the file in the editor.

    trinidad-config.xml file selected in application navigator
  2. The file defines the skin that is used in the skin-family element. Change the skin-family to simple.desktop. The simple skin is often chosen as a starting point for creating a custom skin.

    changed skin-family to simple

  3. Save all your work and refresh the page in the browser. Notice the changes in the look and feel of the application.
