[jboss-user] [JBoss Seam] - @Unwrap onto SFSB
Hi All,
I have 2 'manager component' style beans. One called the 'Accountant' and
the other 'User'. The idea is that in the session I store the id of these things
and in my managers I get the real objects. Both are ScopeType.CONVERSATION. Both also
use SLSB's to make the call to get the data.
The idea is that I want it to be transparent to the application code that these objects
are infact reread if they have not been cached in any current conversation.
The User manager is itself a SFSB while the Accountant is a POJO (I'm trying to see
the results of both methods).
Now in another SFSB (my action handler) I get some odd results using the above...
My first question is:
1) If I Inject @In(value="User", required=true) I works first time the page is
displayed, but second time get get a transaction not open exception. If I change this to
@In(value="User", create=true) it works ?
2) If I Inject @In(value='Accountant', create=true) I get a
6:23:48,343 WARN [Contexts] Could not destroy component: accountantCRUDBean
| javax.ejb.EJBNoSuchObjectException: Could not find Stateful bean:

| but apart from that it works ?
Here is my code:
| @Stateful
| @Name(UserComponentNames.User)
| @Scope(ScopeType.CONVERSATION)
| public class UserComponentManagerBean implements UserComponentManager {
|
| @In(value=UserComponentNames.UserId,required=false)
| private Long userId = null;
|
| @EJB
| private UserManagerLocal userManager;
|
| @Logger private Log log;
|
| private User cachedUser=null;
|
| @Create
| public void create() {
| log.info("create");
| }
|
| @Unwrap
| public User getUserComponent() {
| if ( cachedUser!=null ) {
| return cachedUser;
| }
| if ( userId!=null ) {
| cachedUser = userManager.getUser(userId);
| return cachedUser;
| }
| return null;
| }
|
| @Destroy @Remove
| public void destroy() {
| log.info("destroy");
| }
| }
|
| @Name(AccountantComponentNames.Accountant)
| @Scope(ScopeType.CONVERSATION)
| public class AccountantComponentManager {
|
| @In(value=AccountantComponentNames.AccountantId,required=false)
| private Long accountantId = null;
|
| @In(create=true)
| private CompanyManagerLocal companyManagerLocal;
|
| private Accountant cachedAccountant=null;
|
| @Unwrap
| public Accountant getAccountantComponent() {
| if ( cachedAccountant!=null ) {
| return cachedAccountant;
| }
| if ( accountantId!=null ) {
| cachedAccountant = companyManagerLocal.getAccountant(accountantId);
| return cachedAccountant;
| }
| return null;
| }
| }
|
| @Stateful
| @Scope(ScopeType.CONVERSATION)
| @Name("accountantCRUDBean")
| public class AccountantCRUDBean extends StandardCRUDBean<Accountant> implements
AccountantCRUD, Serializable {
| private static final long serialVersionUID = 1L;
|
| @In(value=AccountantComponentNames.Accountant, create=true)
| private Accountant userLinkedAccountant=null;
|
| @In(value=UserComponentNames.User, create=true)
| private User user;
|
| @EJB
| private CompanyManagerLocal companyManager=null;
