[JBoss AOP] - Newbie help needed
by bdruth
Good afternoon -
I am trying to use JBoss AOP 1.5 annotations, and I think I'm missing something.
I have defined an annotation:
@Retention(RetentionPolicy.RUNTIME)
| @Target({ ElementType.METHOD })
| public @interface MyAnnotation{
| }
And I have applied this annotation to a method:
@MyAnnotation
| public static void testAdvice() throws InterruptedException {
| // do something
| }
|
I have created & annotated an 'Aspect' -
@Aspect (scope = Scope.PER_VM)
| public class MyAdvice {
|
| /**
| * Default public constructor.
| *
| */
| public MyAdvice() {
| }
|
| /**
| * Invokes the advice on the provided invocation (method call).
| * @param invocation The method call to advise
| * @return The result of the invocation
| * @throws Throwable Thrown from {@link Invocation#invokeNext invokeNext()}
| */
| @Bind (pointcut = "execution(* *->@com.package.name.MyAnnotation(..))")
| public Object invoke(Invocation invocation) throws Throwable {
| try {
| obj = invocation.invokeNext();
| } finally {
| // do something
| }
|
| return obj;
| }
| }
|
Nothing in jboss-aop.xml ... unfortunately, the Aspect is never invoked. I've set breakpoints, no use. I'm running under JBoss IDE in Eclipse, using a JBoss AOP Application launch configuration, amended with a -javaagent: argument that provides the path to jboss-aop-jdk50.jar (in eclipse/plugins/.../)
No errors, no output, nothing happens.
Guidance would be appreciated.
Respectfully,
Brice Ruth

[JBoss Seam] - SeamTest - It's not @In-jecting bean attributes
by bsmithjj
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
