If you can use the Internet to check e-mail, then you can use this book to understand Drupal. I really try to emphasize the point-and-click nature of Drupal throughout this book, although sometimes you will need to write a line of HTML or CSS. You may also run into situations where you ask the question, How do I get Drupal to do XYZ More often than not, this is simply a case of searching Drupal.org to find out how someone else solved the problem. To succeed as a Drupal site builder, you need to have a crystal-clear understanding of how your web site works. More specifically, you need to understand which data are collected and how they are displayed. If you understand this, then you can create some of the best web sites on the Internet using Drupal.

throw new NotImplementedException(); } void shape_MouseLeftButtonDown(object sender, MouseButtonEventArgs e) { throw new NotImplementedException(); } Now we are going to create a method that will get the original color of the shape object. Do that now:

@PreDestroy public void cleanup() {

try { connection.close(); } catch (SQLException sqle) { sqle.printStackTrace(); } }

method, type GetOriginalColor(shape); and then press Control+. (period) again. Visual Studio will ask whether you want to generate the method for GetOriginalColor. You do, so press the Enter key. You should now have a method for GetOriginalColor, as I have below: protected override void OnAttached() { base.OnAttached(); shape = this.AssociatedObject as Shape; shape.MouseLeftButtonDown += new MouseButtonEventHandler(shape_MouseLeftButtonDown); shape.MouseLeftButtonUp += new MouseButtonEventHandler(shape_MouseLeftButtonUp); GetOriginalColor(shape); } private void GetOriginalColor(Shape shape) { throw new NotImplementedException(); }

private Long getBidId() { ... } public void cancelBid(Bid bid) {...} public List<Bid> getBids(Item item) {...} ... } Designates remote ... business interface @Remote public interface BidManager { void addBid(Bid bid); void cancelBid(Bid bid); List<Bid> getBids(Item item); }

To keep this book as clear and easy to follow as possible, the following text conventions are used throughout. Important words or concepts are normally highlighted on the first appearance in bold type. Code is presented in fixed-width font. New or changed code is normally presented in bold fixed-width font. Pseudocode and variable input are written in italic fixed-width font . Menu commands are written in the form Menu Submenu Submenu. Sometimes code won t fit on a single line in a book. Where this happens, I use an arrow like this: . This is a very, very long section of code that should be written all on the same line without a break.

As you ve seen before, the @Stateless annotation marks the POJO as a stateless session bean b. The BidManagerBean class implements the BidManager interface, which is marked @Remote F. We use the @Resource annotation to perform injection of a JDBC data source C. The BidManagerBean has a no-argument constructor that the container will use to create instances of BidManagerBid EJB object. The PostConstruct D and PreDestroy E callbacks are used to manage a JDBC database connection derived from the injected data source. Finally, the addBid business method adds a bid into the database. We ll start exploring the features of EJB 3 stateless session beans by analyzing this code next, starting with the @Stateless annotation.

typing the following code: void shape_MouseLeftButtonUp(object sender, MouseButtonEventArgs e) { shape.Fill = originalColor; }

The @Stateless annotation marks the BidManagerBean POJO as a stateless session bean. Believe it or not, other than marking a POJO for the purposes of making the container aware of its purpose, the annotation does not do much else. The specification of the @Stateless annotation is as follows:

@Target(TYPE) @Retention(RUNTIME) public @interface Stateless { String name() default "";

MouseLeftButtonUp you can change shape back to originalColor. Here is the code for this: void shape_MouseLeftButtonUp(object sender, MouseButtonEventArgs e) { shape.Fill = originalColor; } void shape_MouseLeftButtonDown(object sender, MouseButtonEventArgs e) {
