JSF and ASP.NET Web Frameworks Quiz

User controls in ASP.NET use the .ascx extension, which distinguishes them from regular .aspx pages and .asmx web services. The 'ascx' naming convention comes from 'ASP.NET Control eXtension.' This file extension identifies reusable user controls that can be embedded in multiple web forms.

The ASP.NET 2.0 web‑user‑control extension (.ascx) defines 11 directive attributes (e.g., Inherits, CodeBehind, ClassName, etc.). The other numbers are off by one or more, so the stored answer of 11 is correct.

The CodeFile attribute in the @Page directive specifies the path to the code-behind file associated with the page. CodePage sets character encoding, ClassName defines the class name, and Description provides documentation. Despite the typo 'folowing,' the question correctly identifies CodeFile as the code-behind reference.

The ASP.NET page lifecycle begins with Init (control initialization), followed by Load (controls populated with data), then PreRender (final state adjustments before rendering), and ends with Unload (cleanup). This sequence ensures controls exist before Load runs, and gives developers a final opportunity in PreRender to modify the page before it renders to HTML.

Cross-Page Posting is an ASP.NET 2.0 feature that allows a form to post to a different page than the one that rendered it, controlled by the PostBackUrl property. Unlike PostBack (posts to same page), ViewState (maintains state), and PreRender (a lifecycle event), Cross-Page Posting specifically enables multi-page form submissions for scenarios like data collection across multiple pages.

The App_Code folder in ASP.NET 2.0 is a special application folder for storing class files, WSDL files, and typed datasets that are automatically compiled at runtime. App_Data stores database files, App_Theme contains theme files, and App_Browsers holds browser capability definitions - each serving different purposes in the application structure.

Session_Start fires when a new user session begins, which happens on the first request from a user. Application_Start runs once when the application starts (not per user), Application_BeginRequest fires on every request, and Session_OnBegin is not a valid event name - the correct syntax is Session_Start.

JSF is a component-based framework where UI components are the core building blocks. The framework handles events (like button clicks), performs server-side validation, converts data between view and model, and manages page navigation. Option A incorrectly mentions client-side validation and cookies, which are not core JSF concerns.

JSF has built-in support for internationalization (i18n) through resource bundles and locale handling. It provides accessibility features compliant with standards, and the framework is designed to be extensible - developers can create custom components, validators, converters, and renderers.

The JSF framework involves page authors, application developers, component writers, architects, and tool vendors; these roles collectively define, build, and maintain JSF applications. The other options list activities or component types rather than stakeholder roles, making them incorrect.

Backing beans (managed beans) in JSF define both properties and methods. Methods can include action handlers (for button clicks), value change listeners, and validation logic. These methods are bound to UI component events, bridging the view and model layers.

JSF beans have scoped lifecycles: Request (per HTTP request), Session (per user session), Application (singleton per app), and View (per JSF view, added in JSF 2.0). Option A lists the classic three scopes. Response scope does NOT exist in JSF - this is likely confusion with other frameworks.

In JavaServer Faces (JSF), application configuration settings such as managed beans, message bundles, and navigation rules are defined within the faces-config.xml deployment descriptor file.

JSF lifecycle has six phases executed sequentially: Restore View (rebuild component tree), Apply Request Values (decode submitted data), Process Validations (validate inputs), Update Model Values (update bean properties), Invoke Application (call action methods), Render Response (generate output).

JavaServer Faces (JSF) is a server-side UI component framework for building Java web applications. It provides reusable UI components, handles event processing, manages state, and separates presentation from business logic. It is NOT a database server, client-side framework, or script.
