Title: CDI @ApplicationScoped

This example show the use of `@ApplicationScoped` annotation for injected objects. An object
which is defined as `@ApplicationScoped` is created once for the duration of the application.

# Example

This example depicts a similar scenario to cdi-request-scope. A restaurant guest orders
a soup from the waiter. The waiter then delivers the soup back to the guest. Another
guest can order the same soup that was ordered by the previous client - this is where
the application scope is used. 

## Waiter

The `Waiter` session bean receives a request from the test class via the `orderSoup()` method
and sets the name for the `soup` field. The `orderWhatTheOtherGuyHad()` method returns
the name of the `soup` field.

    @Stateless
    public class Waiter {

        @Inject
        public Soup soup;

        public String orderSoup(String name){
            soup.setName(name);
            return soup.getName();
        }

        public String orderWhatTheOtherGuyHad() {
            String name = soup.getName();
            return name;
        }
    }

## Soup

The `Soup` class is an injectable POJO, defined as `@ApplicationScoped`. This means that an instance
will be created only once for the duration of the whole application. Try changing the `@ApplicationScoped`
annotation to `@RequestScoped` and see what happens.

    @ApplicationScoped
    public class Soup {

        private String name = "Soup of the day";

        @PostConstruct
        public void afterCreate() {
            System.out.println("Soup created");
        }

        public String getName() {
            return name;
        }

        public void setName(String name){
            this.name = name;
        }
    }


# Test Case

This is the entry class for this example. First a soup is ordered via `orderSoup()` method.
This initiates the `soup` field. Next, `orderWhatTheOtherGuyHad()` method returns the soup
from the application context.

    public class RestaurantTest {

        private static String TOMATO_SOUP = "Tomato Soup";
        private EJBContainer container;

        @EJB
        private Waiter joe;

        @Before
        public void startContainer() throws Exception {
            container = EJBContainer.createEJBContainer();
            container.getContext().bind("inject", this);
        }

        @Test
        public void orderSoup(){
            String someSoup = joe.orderSoup(TOMATO_SOUP);
            assertEquals(TOMATO_SOUP, someSoup);

            String sameSoup = joe.orderWhatTheOtherGuyHad();
            assertEquals(TOMATO_SOUP, sameSoup);
        }

        @After
        public void closeContainer() throws Exception {
            container.close();
        }
    }

# Running

In the output you can see that there is just one `Soup` instance created - one for
the whole application.
