Settings end up encoded as variables. As you saw when looking through the plist editor, each individual preference is an NSString, an NSArray, an NSNumber, or a Boolean. You can access these variables using the shared NSUserDefaults object. We already discussed this class in the last section; it so happens that Apple s settings bundle uses it, as we suggested you might. The functionality remains the same. You can create it as follows:

The service layer will be pretty straightforward. Since this is a book about iBATIS, we will utilize the iBATIS DAO within the service classes. The iBATIS DAO will be used to retrieve and store the data access object instances as instance variables on the service classes. This will allow us to hide the DAO implementation from the

The allowed MatchModes are START, END, ANYWHERE, and EXACT. An extremely powerful feature of HQL is the ability to call arbitrary SQL functions in the where clause. If your database supports user-defined functions (most do), you can put this functionality to all sorts of uses, good or evil. For the moment, let s consider the usefulness of the standard ANSI SQL functions upper() and lower(). They can be used for case-insensitive searching:

We will not cover the XML syntax in detail, since you do not need to understand it to use this API. Detailed information about this syntax is available in the specification, should you need it.

When you want to define a method in a JavaScript object, you usually do so by assigning a function to a property of the object. Recall from chapter 3 that functions assigned to properties of an object can be invoked using the name of the property. For this reason, there s no need to specify a name for the function, which can be declared anonymous. You can see this in listing 13.1, which defines a Person class using the Microsoft Ajax Library:

Now, let s add a little JavaScript to add the autocomplete behavior:

Saving time by skipping unnecessary steps: <uptodate> To determine if target files are up-to-date with source files, Ant provides the <uptodate> task. Most tasks (such as <javac>) deal with source/target out-of-date checking internally, but there are cases where it is necessary to do this yourself. For example, the JUnit test (see chapter 4 for in-depth coverage) task does no dependency checking and simply runs all tests regardless of whether or not any .class files were modified. Skipping the unit test target if all the test related files are up-to-date dramatically improves build time without sacrificing integrated testing:

If any method in the inner try-catch block threw an exception, we have to roll back the transaction and rethrow the exception. The Session must always be closed, freeing database resources. The outer try-catch block is responsible for exceptions thrown by Session.close() and Transaction.rollback() and, of course, the rethrown inner exception. The first thing wrong with this implementation is the clutter caused by all the session, transaction, and exception-handling code. Since this code is typically identical for all actions, we d like to centralize it somewhere. One option is to place it in the execute() method of an abstract superclass of our actions. We also have a problem with lazy initialization if we access the new bid on the showSuccess.jsp page: By the time we get to the JSP, the Hibernate session is already closed, so we can t access unfetched lazy associations. We encourage you to think about this issue; we made the experience that this might not be obvious for new Hibernate users. A great solution to both problems is the thread-local session pattern. The thread-local session A thread-local session is a single session instance associated with a particular request. It lets you implement a persistence context, similar to the JTA notion of a transaction context. Any components called in the same request will share the same session and persistence context. It s especially useful to include a JSP in the persistence context. The JSP pulls information from the domain model by navigating the object graph beginning at some persistent object in the session or request scope for example, the newly created bid that was placed in the request scope by our action. However, the object graph might include uninitialized associations (proxies or collections) that must be traversed (and initialized) while rendering the view. In our example, the JSP might list all items the current bidder has for sale by calling newBid.getBidder().getItems().iterator(). (This sounds a little contrived, but it s certainly possible.) Since the items association is lazy, it would be unfetched at this point. But we already closed the Hibernate session at the end of the action s execute() method, so Hibernate will throw a LazyInitializationException when the association is accessed the database connection is no longer available, and the object graph is detached, so Hibernate can t fetch the collection. It s possible to write our action to ensure that all needed associations are fully initialized before forwarding
