Why is the URL showing search.jsf Shouldn t it be edit.jsf Consider the request processing of the JSF servlet. If the user clicks the Search button on the search.jsf page, the backing bean s doSearch() method runs after input validation. If the outcome of that method triggers a forward to the edit.xhtml page, this document is rendered by the JSF servlet, and the HTML is sent to the browser. The URL doesn t change! Users can t bookmark the edit page, which in this simple application is desirable. Now that you ve completed the top layer of the application, the view, consider the layer that accesses the database (you might call this the business layer). Because accessing an SQL database is a transactional operation, you write an EJB. Accessing the database in an EJB If you ve worked with EJB 2.x (and Struts) before, the code that accesses the database is most likely procedural code in a stateless session bean. Let s do that in EJB 3.0 (listing 17.4).

Note The $ and @ characters that denote global variables and object variables (as demonstrated in the next section) are technically called sigils. Many developers are, however, unaware of this. This book is not beyond giving you knowledge that can make you more popular at cocktail parties!

The fourth and final call to ProcessItems demonstrates how delegates can be linked together to form a chain. In this example, a reference variable to a Feedback delegate object, fb, is created and initialized to null. This variable points to the head of a linked list of delegates. A value of null indicates that there are no nodes in the linked list. Then a Feedback delegate object that wraps a call to App s FeedbackToConsole method is constructed. The C# += operator is used to append this object to the linked list referred to by fb. The fb variable now refers to the head of the linked list. Finally, another Feedback delegate object is constructed that wraps a call to App s FeedbackToMsgBox method. Again, the C# += operator is used to append this object to the linked list and fb is updated to refer to the new head of the linked list. Now, when ProcessItems is called, it is passed the head of the linked list of Feedback delegates. Inside ProcessItems, the line of code that calls the callback method actually ends up calling all the callback methods wrapped by the delegate objects in the linked list. In other words, for each item being iterated, FeedbackToConsole will be called immediately followed by FeedbackToMsgBox. I ll explain exactly how a delegate chain works later in this chapter. Everything in this example is type safe. For instance, when constructing a Feedback delegate object, the compiler ensures that App s FeedbackToConsole and FeedbackToMsgBox methods have the exact prototype as defined by the Feed back delegate; that is, both methods must take three parameters (Object and two Int32s) and both methods must have the same return type (void). What would have happened if FeedbackToConsole had been prototyped like this

* Yes, so C# supports variable-length argument lists, but it fakes it. Such methods really have a fixed number of arguments, the last of which happens to be an array. There is only one variable-length Console.WriteLine method, and the compiler is able to determine statically when you use it.

Adding an entry to the Parser.ini file looks intimidating until you realize that the syntax for every entry is exactly the same. First, in the [parsers] section, merely add the following without the quotations, substituting the name of your parser and protocol as appro priate: parser_name.dll = 0: protocol_name
