Automatic binding and scoping of an extended persistence context to the conversation You have a guaranteed identity scope that spans your conversation. A particular conversation has at most one in-memory representation of a particular database row. There are no detached objects, and you can easily compare entity instances with double equals (a==b). You don t have to implement equals() and hashCode() and compare entity instances by business key. No more LazyInitializationExceptions when you access an uninitalized proxy or collection in a conversation The persistence context is active for the whole conversation, and the persistence engine can fetch data on demand at all times. Seam provides a much more powerful and convenient implementation of the Open Session in View pattern, which avoids detached objects not only during a single request but also during a whole conversation. Automatic wrapping of the JSF request in several system transactions Seam uses several transactions to encapsulate the phases in the JSF request lifecycle. We ll discuss this transaction assembly later; one of its benefits is that you have an optimized assembly that keeps database lock times as short as possible, without any coding.

Explain System Restore. Enable or disable System Restore. Create a restore point. Restore a restore point.

System Restore works by creating restore points that contain a snapshot of the Registry (which includes user account, application, and hardware configuration) and a copy of certain system files that Windows XP Professional requires for startup, including those in the %systemroot% directory and boot files on the system partition. You can restore your computer to a particular restore point at any time. By default, System Restore creates restore points when the following events occur:

Let s demonstrate this with an example by rewriting the registration procedure from the previous section as a conversation with an extended persistence context. The previous implementation was basically stateless: The RegisterBean was only scoped to a single event.

Every 24 hours if the computer is turned on or if it has been 24 hours since the computer was last turned on When you install an unsigned device driver When System Restore compliant applications are installed When updates are installed through Automatic Updates or Windows Update When you restore data from backup media using Windows Backup When you restore a restore point When certain system or application files are changed When you create a restore point manually

System Restore also monitors file operations for a core set of system and application files. These files are specified in %systemroot%\System32\Restore\Filelist.xml. System Restore records changes to these file and sometimes copies them to a hidden archive before allowing the files to be overwritten, deleted, or changed.

Go back and read the code shown in listing 17.16. This stateful session bean is the backing bean for the account registration page in CaveatEmptor. When a user opens or submits the registration page, an instance of that bean is created and active while the event is being processed. JSF binds the form values into the bean (through verifyPassword and the Seam-injected currentUser) and calls the action listener methods when necessary. This is a stateless design. Although you use a stateful session bean, its scope is a single request, the event context in Seam. This approach works fine because the conversation the user goes through is trivial only a single page with a single form

has to be filled in and submitted. Figure 17.13 shows a more sophisticated registration procedure. The user opens register.xhtml and enters the desired username and password. After the user clicks Next Page, a second form with the profile data (first name, email address, and so on) is presented and must be filled out. The last page shows all the account and profile data again, so the user can confirm it (or step back and correct it). This registration procedure is a wizard-style conversation, with the usual Next Page and Previous Page buttons that allow the user to step through the conversation. Many applications need this kind of dialog. Without Seam, implementing multipage conversations is still difficult for web application developers. (Note that there are many other good use cases for conversations; the wizard dialog is common.) Let s write the pages and Seam components for this conversation. The registration page The register.xhtml page looks almost like the one shown in listing 17.15. You remove the profile form fields (first name, last name, email address) and replace the Register button with a Next Page button:

System Restore does not monitor the following files and folders:

The virtual memory paging file Personal user data, such as files in My Documents, Favorites, Recycle Bin, Temporary Internet Files, History, and Temp folders Image and graphics files, such as those with .bmp, .jpg, and .eps extensions Application data files with extensions not listed in systemroot\System32\Restore\ Filelist.xml, such as .doc, .xls, .mdb, and .pst
