Java Server Faces MCQ Quiz

Facelets is the default templating system for JSF. It is a view technology that allows the creation of reusable templates for web pages. Facelets uses XHTML syntax and provides a more efficient and flexible way to build user interfaces compared to other templating systems. It supports component-based development and allows for easy integration with JSF's lifecycle and event model. Facelets also offers features like composition, templating, and reusability, making it a popular choice for building JSF applications.

The correct answer is h:selectOneRadio. This is because h:selectOneRadio is a JSF component that creates a radio button. h:outputLink is used to create a hyperlink, h:selectOneMenu is used to create a dropdown menu, and "None of the Above" is not a valid JSF component.

Ajax is often used with JSF (JavaServer Faces) to enhance the user experience by allowing asynchronous communication between the client and server. Ajax enables dynamic updates of web pages without reloading the entire page, which is particularly useful in JSF applications where user interactions often require updating specific parts of the page. COBIT, Grails, and JCL are not commonly associated with JSF.

The correct answer is h:Link. This JSF tag provides an HTML anchor, which is used to create a hyperlink in a web page. The h:Link tag is specifically designed for this purpose and allows developers to specify the URL, target, and other attributes of the anchor. The f:attribute tag is used to add custom attributes to a component, h:inputHidden is used to create a hidden input field, and f:param is used to pass parameters to a server-side action.

JSF 2.0 coincides with Java EE 6 because JSF 2.0 was released as part of Java EE 6. Java EE 6 introduced many new features and enhancements, and JSF 2.0 was one of them. It brought significant improvements to JSF, such as improved support for Ajax, better templating mechanisms, and improved handling of events. Therefore, JSF 2.0 is the correct answer as it aligns with the release of Java EE 6.

In the MVC design pattern, the Model carries the login and data. The Model represents the data and business logic of the application. It is responsible for managing the data, validating user input, and performing the necessary calculations and operations. The Controller handles the user's interactions and updates the Model accordingly. The View is responsible for displaying the data from the Model to the user. Therefore, the Model is the component that carries the login and data in the MVC design pattern.

The h:selectOneMenu tag in JSF provides an HTML combo box. This tag is used to create a dropdown list of options, allowing the user to select only one option at a time. Therefore, h:selectOneMenu is the correct answer for this question.

The correct answer is f:validateDoubleRange because this validator tag is specifically used to validate float values within a specified range. The other options, f:validatefloat, f:validateLongRange, and f:validateRegex, are not suitable for validating float values.

JSF 1.2 coincides with Java EE 5 because JavaServer Faces (JSF) 1.2 was released as part of Java EE 5. Java EE 5 introduced several new features and enhancements, including support for JSF 1.2. Therefore, JSF 1.2 is the version of JSF that is compatible with Java EE 5.

JSF 1.0 was released in 2004. This means that the initial version of JavaServer Faces, a Java web application framework, was made available to the public in that year.
