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

Help?
Thanks
