[jboss-user] [JBoss Seam] - Problem when destroying conversational SB
Hi all,
with a certain component I always get the following exception, even though I followed all
the guidance in http://wiki.jboss.org/wiki/Wiki.jsp?page=JbossTimeoutSettingForSeam.
| Could not destroy component: interview
| javax.ejb.EJBNoSuchObjectException: Could not find Stateful bean:

A strange thing I noticed is, that also there exists only one interview component in
conversation scope (checked via debug page), every log message appears two times:
| 16:38:46,827 INFO [InterviewAction] Creating class
de.codest.easyCV.logic.InterviewAction - hashCode: 23232015
| 16:38:46,827 INFO [InterviewAction] Creating class

| ...

| ...

| 16:44:47,781 INFO [InterviewAction] EMERGENY SENDING profile to mail(a)somewhere.com
| 16:44:47,795 WARN [Contexts] Could not destroy component: interview

org.jboss.ejb3.cache.simple.SimpleStatefulCache.get(SimpleStatefulCache.java:268)
| ...
|
But the exception shows only once.
This is the bean code (excerpt):
| @Stateful
| @Name("interview")
| @Scope(ScopeType.CONVERSATION)
| @Conversational(ifNotBegunOutcome="home")
| @CacheConfig(idleTimeoutSeconds=1800)
|
| public class InterviewAction implements Interview {
|
| ProfileInterface profile;
|
| @Create
| public void init() {
| log.info("Creating "+this.getClass()+" - "+this.hashCode());
| }
|
|
| @Begin(ifOutcome="startInterview")
| public String startInterview() {
| ....
|
| log.info("Started interview.");
| state = Status.Interviewing;
| return "startInterview";
| }
|
| @Remove @Destroy
| /** This method is used to send the input data (= profile) by mail to
| the user if the session should expire unexpectedly **/
| public void destroy() {
| log.info("Destroying "+this.getClass()+" - "+this.hashCode());
| // emergency sending of profile when destroyed from interview
| state
| if (isInterviewing()) {
| log.info("EMERGENY SENDING profile to "+getEmail());
| // forced interrupt
| profile.interrupt();
| sendProfileToUser();
| }
| }
|
So there should be sent a mail, when the bean is destroyed from the
"interviewing" state, but this doesn't happen (though it did already work
sometimes).
If you need further information I'll be glad to give it to you. Thanks in advance for
any comments and help.
Regards,
Jörg
