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.


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.


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.

public class Waiter {

    public Soup soup;

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

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


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.

public class Soup {

    private String name = "Soup of the day";

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

    public String getName() {
        return name;

    public void setName(String 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;

    private Waiter joe;

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

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

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

    public void closeContainer() throws Exception {


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