Figure 7-12. Clicking the link next to the Style label in the Style se ttings category opens a form to select a style plug-in. I broadly categorize each column as settings, display, and logics, separated (mostly) by the left, center, and right columns. I m going to divide the rest of this chapter into separate sections accordingly, with the goal of explaining how to add a view.

String mappedName() default ""; String description() default ""; }

The single parameter, name, specifies the name of the bean. Some containers use this parameter to bind the EJB to the global JNDI tree. Recall that JNDI is essentially the application server s managed resource registry. All EJBs automatically get bound to JNDI as soon as they catch the container s watchful eye. You ll see the name parameter in use again in chapter 11 when we discuss deployment descriptors. In listing 3.1, the bean name is specified as BidManager. As the annotation definition shows, the name parameter is optional since it is defaulted to an empty String. We could easily omit it as follows:

shape.Fill = new SolidColorBrush(Colors.Red); }

@Stateless public class BidManagerBean implements BidManager {

In the left column, you see category settings for the display, including View settings (available only on Defaults display) Basic settings, Advanced se ttings, and Style settings, plus a category for e xposed form If you re looking at a page, block, or feed display, a corresponding settings category will appear underneath Exposed form, and the View se ttings category will disappear View se ttings are global settings for the view, including Description/Tag, which appears on the view module s administrative UI This is the only category that is specific to the Defaults display; the remaining categories (Basic, Advanced, Style) appear on and can be overridden at the Page, Block, and Feed display levels The Basic settings category has a number of settings You may need to change the display Name if you have a number of views; this is also the name that appears in the left display column.

If the name parameter is omitted, the container assigns the name of the class to the bean. In this case, the container assumes the bean name is BidManagerBean. mappedName is a vendor-specific name that you can assign to your EJB; some containers, such as the GlassFish application server, use this name to assign the global JNDI name for the EJB. As we noted, the BidManagerBean implements a business interface named BidManager. Although we ve touched on the idea of a business interface, we haven t dug very deeply into the concept. This is a great time to do exactly that.

4. Your completed code should now look like this:

In section 3.1, we introduced you to EJB interfaces. Now let s explore a bit more how they work with stateless session beans. Client applications can invoke a stateless session bean in three different ways. In addition to local invocation within the same JVM and remote invocation through RMI, stateless beans can be invoked remotely as web services. Three types of business interfaces correspond to the different access types; each is identified through a distinct annotation. Let s take a detailed look at these annotations. Local interface A local interface is designed for clients of stateless session beans collocated in the same container (JVM) instance. You designate an interface as a local business interface by using the @Local annotation. The following could be a local interface for the BidManagerBean class in listing 3.1:

namespace SimpleBehavior { public class FillBehavior : TargetedTriggerAction<FrameworkElement> { private Shape shape; private Brush originalColor; protected override void Invoke(object parameter) { } 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) { originalColor = shape.Fill as Brush; } void shape_MouseLeftButtonUp(object sender, MouseButtonEventArgs e) { shape.Fill = originalColor; } void shape_MouseLeftButtonDown(object sender, MouseButtonEventArgs e) { shape.Fill = new SolidColorBrush(Colors.Red); } } } Press F6 to recompile the application. Switch back to Blend and reload the application if prompted. Now it is time to actually add the FillBehavior to a Shape. To do that you need to first add a Shape such as a

@Local public interface BidManagerLocal { void addBid(Bid bid); void cancelBid(Bid bid); List<Bid> getBids(Item item); }
