The free cinema website template is fashionable and will attract the attention of every Internet user who will see it. Not long ago a team of TemplateMonster Blog presented you some information about a new version of well known markup language for the web – HTML5. If you are interested in the proposition of the free HTML5 template than you are welcome to download source files in two ways: with PSD source files included and without them.
You may enjoy this Free Website Template whether you are building a personal site or a business one. It seems you’ll be pleased with Green Planet Website Template as it is very clean, tidy and fresh. This chapter describes the steps you may need to take before using the Data Controls panel to create databound UI components on JSF pages.
Most of what you need to know to get started with your web interface is covered in the Oracle Fusion Middleware Web User Interface Developer's Guide for Oracle Application Development Framework. Additionally, the lifecycle of a Fusion web application is different from that of a standard JSF or ADF Faces application.
As you design the flow of your application, you can begin to think about the design of your pages. For example, the StoreFront module of the Fusion Order Demo application contains a page template that provides a top area for branding and navigation, a bottom area for copyright information, and a center area for the main content of the page. In addition to using ADF Faces components to build a page template, you can add attributes to the template definition.
In this page template, facet references are used inside four different panelSplitter components.
When you choose to add databound components to a page template, an associated page definition file and the other metadata files that support ADF Model layer data binding are created. For example, if you wanted a list of products to appear on each page that uses the page template, you could drag and drop the ProductName attribute of the Products collection as a list. If a page template does not contain databound components, it can be referenced dynamically by the calling page using an EL expression.
If the page template has databound components, setting the viewId with an EL expression is not enough.
For databound page templates, you use the pageTemplateModel to manage both the page template Id and the associated binding container. Creating a page template for use in an application that uses ADF Business Components and ADF Model layer data binding is the same as creating a standard ADF Faces page template, as documented in the "Using Page Templates" section of the Oracle Fusion Middleware Web User Interface Developer's Guide for Oracle Application Development Framework. The Create JSF Page Template wizard also allows you to create model parameters for use by the template. Create a page template following the instructions in the "How to Create a Page Template" section of the Oracle Fusion Middleware Web User Interface Developer's Guide for Oracle Application Development Framework. You can now use the Data Controls panel to add databound UI components to the page, as you would for a standard JSF page, as described in the remaining chapters in this part of the book. If your template contains any method actions bound to a method iterator, you cannot change the value of the refresh attribute on the iterator to anything other than Default.
When you add ADF databound components to a template or create model parameters for a template, a page definition file is created for the template, and any model parameters are added to that file.
Example 20-2 shows what the page definition file for a template for which you created a productId model parameter might look like.
Parameter binding objects declare the parameters that the page evaluates at the beginning of a request. In order to access the template's binding objects, the page definition file for the calling page must instantiate the binding container represented by the template's page definition file. Because there is an ID for this reference (in this case, pageTemplateBinding), the calling page can have components that are able to access values from the template. Additionally, when the template contains any ADF data binding, the value of that tag is the ID set for the calling page's reference to the template's page definition, as shown in Example 20-4. You can dynamically add a page template without databound components by using an EL expression to select the page template.
This section describes how to dynamically add a page template with databound components to a page. You use the pageTemplateModel to dynamically manage a page template and its binding container.
Add a viewId attribute and set it to an EL expression with a managed bean method that returns the current page template Id. Create a pageFlowScope managed bean with a method that returns the current page template Id. During the Initialize Context phase, the binding container for the calling page is created based on the page definition file. The lifecycle continues, with UI components and bindings from both the page and the template being processed. Creating a web page for an application that uses ADF Model layer data binding is no different than described in the "Creating a JSF Page" section in the Oracle Fusion Middleware Web User Interface Developer's Guide for Oracle Application Development Framework.
When you begin adding content to your page, you typically use the Component Palette and Data Controls panel of JDeveloper. Managed beans are Java classes that you register with the application using various configuration files.
Often, managed beans handle events or some manipulation of data that is best handled at the front end. In an application that uses ADF data binding and ADF task flows, managed beans are registered in different configuration files from those used for a standard JSF application.
Registering managed beans within the faces-config.xml file is not recommended in a Fusion web application. Managed beans accessed within the task flow definition must be registered in that task flow's definition file. Managed bean definitions within task flow definition files will be visible only to activities executing within the same task flow.
When executing within a bounded task flow, faces-config.xml will be checked for managed bean definitions before the currently executing task flow definition.
As a general rule for Fusion web applications, a bean that may be used in more than one page or task flow, or one that is used by pages within the main unbounded task flow (adfc-config), should be registered in the adfc-config.xml configuration file.


If you create managed beans from dialogs within JDeveloper, the bean is registered in the adfc-config.xml file, if it exists. This section describes how to create a managed bean for use within a task flow (either the default adfc-config flow or any bounded task flow).
Within the editors for a task flow definition, you can create a managed bean and register it with the JSF application at the same time. In the Application Navigator, double-click either the adfc-config.xml file or any other task flow definition file. If your managed bean takes part in component binding by accepting and returning component instances (that is, if UI components on the page use the binding attribute to bind to component properties on the bean), then the managed bean must be stored in BackingBean scope. Use the sessionScope scope only for information that is relevant to the whole session, such as user or context information. While you can declare managed properties using this editor, the corresponding code is not generated on the Java class.
When you use the configuration editor to create a managed bean and elect to generate the Java file, JDeveloper creates a stub class with the given name and a default constructor. Typically, in an application that runs in a clustered environment, a portion of the application's state is serialized and copied to another server or a data store at the end of each request so that the state is available to other servers in the cluster. If the managed bean will be calling set and get methods on ADF Faces components, you cannot serialize the managed beans because ADF Faces components are not serializable. To identify failures with objects stored in page flow scope and view scope, use writeObject(). Make sure that the framework is aware of changes to managed beans stored in ADF scopes (view scope and page flow scope). When a value within a managed bean in either view scope or page flow scope is modified, the application needs to notify the framework so that it can ensure that the bean's new value is replicated. Without additional code, the framework will be unaware of this change and it will not know that a new value needs to be replicated within the cluster. This code is needed for any request that modifies an existing object in one of the ADF scopes.
If an application is not deployed to a clustered environment, the tracking of changes to ADF memory scopes is not needed, and by default, this functionality is disabled.

However, using the ADF Model layer for data binding instead of JSF managed beans provides additional functionality, such as the ability to declaratively bind components to your business services.
Page developers do not need to do anything to the branding and copyright information when they use the template.
These attributes provide placeholders for specific information that the page developer needs to provide when using the page template.
When the home page was created using this page template, the navigational links were placed in the Header facet and the accordion panels that hold the navigation trees and search panels were placed in the Start facet. Each component is bound in the same fashion as for standard JSF pages, as described in Chapter 12, "Using ADF Model in a Fusion Web Application." You can also create model parameters for the page template. Or, if you wanted the pages to display the currently selected product ID, you could create a model parameter for the page template that would evaluate to that product's ID.
While they can be reused between projects and applications, they are not fully self-contained and will always have some dependencies to external resources, for example, any ADF data binding, Strings from a message bundle, images, and managed beans. Because databound components require access to the binding container, you must specify the page template as well as its associated binding container. JDeveloper automatically adds the page definition file when you drag and drop items from the Data Controls panel. Use the order buttons to arrange the parameters into the order in which you want them to be evaluated.
For more information about binding objects and the ADF lifecycle, see Chapter 12, "Using ADF Model in a Fusion Web Application." However, since a template itself is never executed, the page that uses the template (the calling page) must access the binding objects created for the template (including parameters or any other type of binding objects created by dragging and dropping objects from the Data Controls panel onto the template).
As a result, a reference to the template's page definition is inserted as an executable into the calling page's page definition file, as shown in Example 20-3.
When you create a JSF page from a template, instead of you having to repeat the code contained within the template, you can use the af:pageTemplate tag on the calling page. In this example, gettemplateViewId() obtains the user's page template selection and returns the page template Id.
At this point, the binding container for the template is created based on the template's page definition file, and added to the binding context. You can create pages either by double-clicking a view activity in a task flow or by using the New Gallery. In order to add navigation to these files, you have to manually edit the code by clicking the Source tab.
The Component Palette contains all the ADF Faces components needed to declaratively design your page. When the JSF application starts up, it parses these configuration files, and the beans listed within them are made available. All application data and processing should be handled by logic in the business layer of the application. In a standard JSF application, managed beans are registered in the faces-config.xml configuration file. However, any backing beans for page fragments or declarative components should use BackingBean scope.
Therefore, an existing session-scoped managed bean named foo will always take precedence over a request-scoped bean named foo defined in the current task flow definition file. However, managed beans of request scope, of pageFlow scope, of view scope, or with the scope set to none that are to be accessed within the task flow definition must be defined within the task flow definition file. If no match is found in either location, adfc-config.xml and other bootstrap configuration files will be consulted. Therefore, an existing session-scoped managed bean named foo will always take precedence over a request-scoped bean named foo registered in the current task flow definition file.


A managed bean that will be used only by a specific task flow should be registered in that task flow's definition file. Because this bean is used by a page within the adfc-config unbounded task flow, it is registered in the adfc-config.xml file. For more information regarding managed beans and how they are used as backing beans for JSF pages, see the "Creating and Using Managed Beans" section in the Oracle Fusion Middleware Web User Interface Developer's Guide for Oracle Application Development Framework.
If it can't be stored in one of those scopes (for example, if it needs to be stored in sessionScope for high availability reasons), then instead of using component binding, you need to use the ComponentReference API.
While not technically a scope, none means that the bean will not live within any particular scope, but will instead be instantiated each time it is referenced.
With the bean selected in the Managed Beans table, click the Add icon for the Managed Properties table. You will need to add that code by creating private member fields of the appropriate type and then using the Generate Accessors menu item on the context menu of the source editor to generate the corresponding getter and setter methods for these bean properties.
You can then refer to that logic using an EL expression that refers to the managed-bean-name value given to the managed bean. Specifically, beans stored in session scope, page flow scope, and view scope need to be serializable. This method provides additional information in an exception about the object and scope that failed to serialize. To inform the framework that an object in an ADF scope has been modified and that replication is needed, use the markScopeDirty() method, as shown in Example 20-9. If the scope itself is modified by the scope's put(), remove(), or clear() methods, it is not necessary to notify the framework. This week TemplateMonster company presents you an awesome freebie which is intended to solve all on-line problems with your Internet project. If you want to have extra PSD source files than you should type your email address on a free cinema website template download page.
If you want the template with PSD source files then go to the Free HTML5 Website Template download page at TemplateMonster (this link is also available from ) and type the e-mail address you want the HTML5 theme to be delivered to. However, it can also be used for a personal blog, health care blog, agricultural site, charity site, or any other kind of site. These page templates provide structure and consistency for other developers building web pages. For example, the page template in the StoreFront module application contains an attribute for a welcome message. The cart summary was placed in the End facet, and the main portion of the page was placed in the Center facet.
You must also modify the page executable section of the calling page's page definition file and create a managed bean with methods to process the page template Ids.
JDeveloper automatically adds the page definition file when you drag and drop items from this panel.
You can use the pageTemplateModel from the corresponding page definition file's page executable binding. When creating the page (or dropping a view activity onto a task flow), you can choose to create the page as a JSF JSP or as a JSF JSP fragment.
Once you have the basic layout components placed on the page, you can then drag and drop items from the Data Controls panel to create ADF Model databound UI components.
The managed beans can be referenced in an EL expression, allowing access to the beans' properties and methods. Therefore, a request-scoped managed bean named foo in the adfc-config.xml file will take precedence over a session-scoped managed bean named foo in the current task flow definition file. However, this lookup in other adfc-config.xml and bootstrap configuration files will only occur for session- or application-scoped managed beans.
Therefore, beans registered in the faces-config.xml file will always win any naming conflict resolution.
Because scope replication has a small performance overhead, it should be enabled only for applications running in a server-cluster environment. Page templates typically contain static areas which cannot be changed when they are used, and dynamic areas, where developers can place content specific to the page they are building. When page developers use this page template, they can add a different welcome message for each page. JSF fragments provide a simple way to create reusable page content in a project, and are what you use when you wish to use task flows as regions on a page. The remaining chapters in this part of the book explain in detail the different types of databound components and pages you can create using ADF Model data binding. Whenever a managed bean is referenced for the first time and it does not already exist, the Managed Bean Creation Facility instantiates the bean by calling the default constructor method on it. This way, you can expose this logic as business service methods, which can then become accessible to the ADF Model layer and be available for data binding.
Which configuration file you use to register a managed bean depends on what will need to access that bean, whether or not it needs to be customized at runtime, what the bean's scope is, and in what order all the beans in the application need to be instantiated. Because it is used solely within the customer-registration task flow, it is registered in the customer-registration-task-flow definition file. You can then use the drop-down menu to choose Generate Class, and the Java file will be created for you. And after this feel free to use the template to satisfy your personal or educational needs.
The af:pageTemplate tag includes a viewId attribute that specifies the page template the page will use.
When you modify a JSF page fragment, the JSF pages that consume the page fragment are automatically updated.
Table 20-1 describes how registering a bean in each type of configuration file affects the bean. But don’t use the template in commercial purposes since it was not made with a view to resale.
You can set viewId with an EL expression to a managed bean method that returns the page template Id, as shown in Example 20-1.
