JSF defines a component programming model for backing beans, or managed beans, which contain the application logic. JSF defines the interaction between the user interface and the application logic and allows you to bind both together in a flexible fashion. JSF allows you to define navigation rules declaratively in XML that is, which page is displayed for a particular outcome in your application logic.

2. If your computer running Windows XP Professional is part of a domain environment and you configure the Local Security Policies on your computer so that you assign yourself the Add Workstation To A Domain user right, can you add additional workstations to the domain Why or why not

For the Add Workstation To A Domain privilege to be effective, it must be assigned as part of the default domain controller policy for the domain, not the Local Security Policy on your computer running Windows XP Professional.

Let s spend a little more time on each of these features and what makes them useful. JSF defines a set of built-in visual components that every JSF implementation has to support (such as buttons and input text fields). These visual components are rendered on pages as HTML (and Javascript). At the time of writing, several high-quality open source and commercial JSF widget libraries are available. Readymade visual components are great for you as a developer; you don t have to code them by hand, and, most important, you don t have to maintain them or make them work on different browsers (which is especially painful if you need more sophisticated visual components that use Javascript). Pages are created with any HTML templating engine that understands JSF widgets. Although JSP seems like an obvious choice, in our experience it isn t the best. We found that JavaServer Facelets (https://facelets.dev.java.net/) is a perfect fit for building JSF views and creating HTML templates that contain JSF widgets. (Another nice bonus of using Facelets is that you get the new unified expression language for free, even without a JSP 2.1-capable servlet container.) We ll use Facelets in all JSF examples in this chapter. JSF-managed application components, called backing beans, make your web application interface work; they contain the application code. These are regular POJOs, and they re defined and wired together in JSF XML configuration files. This wiring supports basic dependency injection, as well as lifecycle management

The Back Up Files And Directories user right improves the security on your system. It allows a user to back up the system without being assigned file and folder permissions to access all files and folders on the system. In other words, the person backing up the files can back up secure files without being able to read them.

A logon right is a user right assigned to a group or individual user account. Logon rights control the way users can log on to a system.

deploying updates to this group means that all computers receive updates without their being adequately tested against the current configuration.

Check that your database is running and that it has the correct database schema. A useful tool included with HSQLDB is a simple database browser. You can call it with the following Ant target:

<target name="dbmanager" description="Start HSQLDB manager"> <java classname="org.hsqldb.util.DatabaseManagerSwing" fork="yes" classpathref="project.classpath" failonerror="true"> <arg value="-url"/> <arg value="jdbc:hsqldb:hsql://localhost/"/> <arg value="-driver"/> <arg value="org.hsqldb.jdbcDriver"/> </java> </target>

1. How can you require a user to be logged on to the computer to shut it down (Discuss using the Welcome screen and using CTRL+ALT+DELETE to log on.)

If Windows XP Professional is configured to use the Welcome screen or CTRL+ALT+DELETE to log on, by default you do not have to log on to shut down the computer. In the console tree, expand Local Policies, and then click Security Options. In the details pane, right-click Shutdown: Allow System To Be Shut Down Without Having To Log On, and then click Properties and click Disabled.
