Shared components are common elements that can display or be applied on any page within an application. You can use the tools and wizards on the Shared Components page either at the application-level or on specific pages.
Topics in this section include:
To access the Shared Components page:
Navigate to the Workspace home page.
Click the Application Builder icon.
Select an application.
On the Application home page, click Shared Components.
The Shared Components page appears.
To create a shared component, select the appropriate link.
You can also access the Shared Components page by clicking the Shared Components icon on the Action bar. The Action bar resembles a small mechanical gear and displays beneath the Utilities tab in the upper right corner of most pages in Application Builder.
See Also:
"About the Action Bar"The following sections describe each link on the Shared Components page.
The following section describes the links under Application.
Links to the Edit Application Definition page. Use this page to edit attributes that determine the application name, application availability, and static substitution strings. You can also use this page to define other attributes such as build options or an application logo and view associated templates and component defaults. See "Configuring the Application Definition".
Use Application Comments to enter comments specific to the currently selected application. See "Adding Application Comments"
The following section describes the links under Logic.
Application-level items do not display, but are used as global variables to the application. Commonly, you set the value of a page-level item using an application or page computations. See "Understanding Application-Level Items".
Use application processes to run PL/SQL logic:
At specific points for each page in an application
As defined by the conditions under which the process is set to execute
Upon the creation of a new session
Note that On Demand processes execute only when called from a page-level On Demand process. See "Understanding Application Processes".
Use application-level computations to assign values to application and page-level items for each page displayed or upon the creation of a new application session. You can also create an application-level computation and execute it conditionally on multiple pages. See "Understanding Application Computations".
Web service references in Application Builder are based on the Simple Object Access Protocol (SOAP). You can create a reference to a Web service and then incorporate it into an application to process data submitted by a form, or to render output in the form or report. See "Implementing Web Services".
Use build options to conditionally display or process specific functionality within an application. You can use build options to control which features of an application are turned on for each application deployment. See "Using Build Options to Control Configuration".
The following section describes the links under Security.
Authentication is the process of establishing each user's identity before they can access your application. Authentication may require a user to enter a user name and password or may involve verification of a user's identity or use of a secure key. See "Establishing User Identity Through Authentication".
Authorization restricts user access to specific controls or components based on predefined user privileges. See "Providing Security Through Authorization".
Session State Protection is a built-in functionality that prevents hackers from tampering with the URLs within your application. URL tampering can adversely affect program logic, session state contents, and information privacy. See "Understanding Session State Protection".
Use the Edit Security Attributes page to configure general security attributes for all pages within an application. See "Configuring Security Attributes".
The following section describes the links under Globalization.
You can develop applications in Oracle Application Express that can run concurrently in different languages. A single Oracle database and Oracle Application Express instance can support an application in multiple languages. Translating an application involves multiple steps. See "About Translating an Application and Globalization Support" and "Understanding the Translation Process".
Text messages are named text strings that can be called from the PL/SQL code you write. This PL/SQL can be anonymous blocks within page processes and page regions, or in packages and procedures. See "Translating Messages".
You can develop applications that can run concurrently in different languages. Click this link to specify globalization options such as the Application Primary Language and Application Language Derived From attributes. See "Configuring Globalization Attributes" and "About Translating an Application and Globalization Support".
The following section describes the links under Navigation.
Tabs are an effective way to navigate users between pages in an application. You can create two types of tabs: standard tabs or parent tabs. A standard tab set is associated with a specific page and page number. A parent tab set functions as a container to hold a group of standard tabs. See "Creating Tabs".
A list is a shared collection of links. You control the appearance of a list through list templates. Each list element has a display condition that enables you to control when it displays. See "Creating Lists".
Breadcrumbs provide users with hierarchical navigation. A breadcrumb is a hierarchical list of links that display using templates. You can display a breadcrumb as a list of links or as a breadcrumb path. See "Creating Breadcrumbs".
A tree is an effective way to communicate hierarchical or multiple level data. See "Creating Trees".
Navigation bar entries offer users a simple navigation path for moving between pages in an application. The location of a navigation bar depends upon the associated page template. Navigation bar entries can display as a link from an image or text. A navigation bar entry can be an image, an image with text beneath it, or text. See "Creating a Navigation Bar Entry".
The following section describes the links under User Interface.
A theme is a named collection of templates that defines the application user interface. See "Managing Themes".
Templates control the look and feel of specific constructs within your application, such as pages, regions, items, and menus. See "Customizing Templates".
User interface defaults enable you to assign default user interface properties to a table, column, or view within a specified schema. When you create a form or report using a wizard, the wizard uses this information to create default values for region and item properties.
Because user interface defaults are associated with a table, you can use them with applications created using the form and report wizards. See "Managing User Interface Defaults".
A list of values (LOV) is a static or dynamic set of values used to display a popup list of values, select list, check box, or radio group. See "Creating Lists of Values".
Use shortcuts to avoid repetitive coding of HTML or PL/SQL functions. You can create a shortcut to define a page control such as a button, HTML text, a PL/SQL procedure, or HTML. Once you define a shortcut, it is stored in a central repository so you can reference it from various locations within your application. See "Using Shortcuts".
The following section describes the links under Reports.
Use the Report Queries link to view a report of stored queries within the current application. See "About Report Queries".
Use Report Layouts with a report or shared query to render data in a printer-friendly format, such as Adobe Portable Document Format (PDF), Microsoft Word Rich Text Format (RTF), or Microsoft Excel (XLS) format. See "About Report Layouts".
The following section describes the links under Files.
Application Builder includes themes that contain templates that reference their own cascading style sheets (CSS). Use the Cascading Style Sheets link to upload cascading style sheets to your workspace. See "Using Custom Cascading Style Sheets".
Use the Static Files link to upload static files to your workspace. See "Managing Static Files".
You can export shared components and page components on the Component Export page. You can also use this wizard to back up a component before editing it or to create an export that functions as a patch to another Oracle Application Express instance.
Topics in this section include:
To export shared components from the Shared Components page:
Navigate to the Export page:
On the Workspace home page, click the Application Builder icon.
Select an application.
On the Application home page, click Export/Import.
On the Export/Import page, click Export and click Next.
On the Tasks list, click Component Export.
The Component Export page appears. See "Exporting Application Components".
