    SeamTest - It's not @In-jecting bean attributes

    Bradley Smith Master

      Hello,

      I have a Stateless Session Bean - here is it's interface and the implementation:

      @Local
      @Remote
      public interface UserEditor {
      
       public String createUser();
      
       public String deleteUser();
      
       public String updateUser();
      
       public String loadUser();
      
       public void setUser(User user);
      
       public User getUser();
      
       public void setUsername(String username);
      }
      


      @Stateless
      @Scope(ScopeType.STATELESS)
      @Name("userEditor")
      public class UserEditorBean implements UserEditor {
      
       @Logger
       private Log log;
      
       private User user;
      
       private String username;
      
       private EntityManager em;
      
       public UserEditorBean() {
       // troubleshooting
       System.out.println("\n new UserEditorBean() \n");
       }
      
      
       public String createUser() {
       try {
       user.initDates();
       em.persist(user);
       return "success";
       } catch (Exception e) {
       e.printStackTrace();
       return null;
       }
       }
      
       public String deleteUser() {
       return null;
       }
      
       public String updateUser() {
       return null;
       }
      
       public String loadUser() {
       return null;
       }
      
       @In
       public void setUser(User user) { this.user = user; log.info("setUser() : user -> "+user); }
       @Out
       public User getUser() { return this.user; }
      
       @In(required = false)
       public void setUsername(String username) {
       this.username = username;
       }
      
       @In
       public void setEm(EntityManager em) {
       this.em = em;
       log.info("setEm (entity manager)");
       }
      
      }


      Here also is the entity this bean will operate on:

      @Entity
      @Table(name = "users",
       uniqueConstraints = {@UniqueConstraint(columnNames = {"username"})}
      )
      @Name("user")
      public class User extends BaseTimestampedEntity implements java.io.Serializable {
      
       private static final long serialVersionUID = -2717302256558315283L;
      
       private String username;
       private boolean enabled;
      
       public User() {System.out.println("\n new User() \n");}
      
       @Column(name = "username", unique = true, nullable = false, insertable = true, updatable = true, length = 255)
       public String getUsername() { return this.username; }
       public void setUsername(String username) { this.username = username; }
      
      
       @Column
       public boolean isEnabled() { return enabled; }
       public void setEnabled(boolean enabled) { this.enabled = enabled; }
      
       public String toString() {
       final StringBuilder sb = new StringBuilder();
       sb.append("User");
       sb.append("{id=").append(id);
       sb.append(", username='").append(username).append('\'');
       sb.append(", enabled=").append(enabled);
       sb.append(", createDate=").append(createDate);
       sb.append(", lastUpdate=").append(lastUpdate);
       sb.append('}');
       return sb.toString();
       }
      }


      Here is my SeamTest:

      public class UserEditorBeanTest extends SeamTest {
      
       Log log = LogFactory.getLog(UserEditorBeanTest.class);
      
       @Test
       public void test_createUser_deleteUser() throws Exception {
      
       new Script() {
      
       UserEditor userEditor;
      
       @Override
       protected void updateModelValues() {
      
       log.info("updateModelValues()");
       User user = (User)getInstance("user");
       assert user != null;
       user.setUsername("Test-Username");
       user.setEnabled(true);
       log.info("user -> "+user);
       userEditor = (UserEditor) Component.getInstance("userEditor");
      
       }
      
       @Override
       protected void invokeApplication() {
      
       log.info("invokeApplication()");
      
       String outcome = userEditor.createUser();
       log.info("outcome = "+outcome);
       assert "success".equals(outcome);
       userEditor.deleteUser();
       }
       }.run();
      
       }
      }


      The problem I am having is that when the SeamTest.Script runs, it is not injecting component(s) onto the UserEditorBean. I am getting a NullPointerException on the first line of the createUser() method where I assume the user has been set and I attempt to initDates(). I've tried putting the code to obtain a "userEditor" component in different methods of Script ( setup(), etc....), but always the NullPointerException occurs.

      Here is a log of the exception that occurs during the test run:

      So I can see that the components are being created, however, it appears that the UserEditorBean is not having a User @In-jected into it.

      Help?

      Thanks
