 <p>This example show the use of <code>@ApplicationScoped</code> annotation for injected objects. An object
 which is defined as <code>@ApplicationScoped</code> is created once for the duration of the application.</p>

 <h1>Example</h1>

 <p>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. </p>

 <h2>Waiter</h2>

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

 <pre><code>@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;
     }
 }
 </code></pre>

 <h2>Soup</h2>

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

 <pre><code>@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;
     }
 }
 </code></pre>

 <h1>Test Case</h1>

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

 <pre><code>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();
     }
 }
 </code></pre>

 <h1>Running</h1>

 <p>In the output you can see that there is just one <code>Soup</code> instance created - one for
 the whole application.</p>

	<p>This example show the use of <code>@ApplicationScoped</code> annotation for injected objects. An object
	which is defined as <code>@ApplicationScoped</code> is created once for the duration of the application.</p>

	<h1>Example</h1>

	<p>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. </p>

	<h2>Waiter</h2>

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

	<pre><code>@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;
	}
	}
	</code></pre>

	<h2>Soup</h2>

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

	<pre><code>@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;
	}
	}
	</code></pre>

	<h1>Test Case</h1>

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

	<pre><code>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();
	}
	}
	</code></pre>

	<h1>Running</h1>

	<p>In the output you can see that there is just one <code>Soup</code> instance created - one for
	the whole application.</p>
