[jboss-user] [JBoss Seam] - Injection at destroy time
I have some stateless beans injected into a stateful bean that are only required at
destroy time. Currently when destroy is invoked, these beans are null. Code is as
follows:
@Name("sessionTimeoutHandler")
| @Stateful
| @Scope(ScopeType.SESSION)
| public class SessionTimeoutHandlerHome implements SessionTimeoutHandler, Serializable
| {
| private static final long serialVersionUID = 1L;
|
| @Logger
| private Log log;
|
| @In(create=true)
| private SessionDao sessionDao; // this is stateless
|
| @In(create=true)
| private AuditLog auditLog; // and so is this
|
| private Session currentSession;
|
| ...
|
| @Remove @Destroy
| public void destroy() {
| // Session has timed out, so update the user session entry and perform
| // cleanup.
| currentSession.setClosed(new Date());
|
| sessionDao.merge(currentSession);
|
| auditLog.addAuditEntry("User session timeout for session id #0"
currentSession.getId());
|
| log.info("User session timeout for session id #0"
currentSession.getId());
| }
| }
Should I be getting the stateless beans injected at this point? I'm sure I've seen
this working in the past.
When creating the bean I did notice what I believe to be inconsistent behaviour with
respect to @Logger injection. I initially created the bean using method 1 below, by
simply specifying the bean as an @Out parameter and instantiating the object within an
action. Using this method, the @Logger object on SessionTimeoutHandler was null when
@Destroy was called. However, when I changed to method 2 the logger was available - but
still no stateless beans.
Creation Method 1 - Using @Out
| @Name("login")
| @Stateful
| @Scope(ScopeType.EVENT)
| public class LoginAction implements Login, Serializable
| {
| @Out(required=false)
| private SessionTimeoutHandler sessionTimeoutHandler;
|
|
| public String login() {
| ...
|
| SessionTimeoutHandler sessionTimeoutHandler = new SessionTimeoutHandler();
|
| // create a session timeout handler
| sessionTimeoutHandler.setCurrentSession(currentSession);
| }
| }
|
|
| Creation Method 2 - Using @In(create = true)
| @Name("login")
| @Stateful
| @Scope(ScopeType.EVENT)
| public class LoginAction implements Login, Serializable
| {
| @In(create = true)
| @Out(required = false)
| private SessionTimeoutHandler sessionTimeoutHandler;
|
|
| public String login() {
| ...
|
| // create a session timeout handler
| sessionTimeoutHandler.setCurrentSession(currentSession);
| }
| }
I am using Seam 1.1 CR2.
