[jboss-user] [EJB 3.0] - Entity EJBs, @Service & Thread

Hi, I'm trying to get a service running on my JBoss server that would awake every now and then, get a list of entity beans and throw a message to a JMS queue for each of those items, and sleep for a while. If I strip the bit loading Entity beans off, everything works, I send a test message to the queue, etc. But if I do the same loading the beans, I get the exception below. I guess I'm doing something wrong but cannot figure out what. | 17:02:32,650 ERROR [STDERR] Exception in thread "Thread-16" | 17:02:32,650 ERROR [STDERR] java.lang.NullPointerException | 17:02:32,650 ERROR [STDERR] at org.jboss.ejb3.entity.ManagedEntityManagerFactory.getNonTxEntityManager(ManagedEntityManagerFactory.java:58) | 17:02:32,650 ERROR [STDERR] at org.jboss.ejb3.entity.ManagedEntityManagerFactory.getTransactionScopedEntityManager(ManagedEntityManagerFactory.java:163) | 17:02:32,650 ERROR [STDERR] at org.jboss.ejb3.entity.TransactionScopedEntityManager.createNamedQuery(TransactionScopedEntityManager.java:132) | 17:02:32,650 ERROR [STDERR] at tal.noc.beans.NOCManagerService.loadNOCs(NOCManagerService.java:79) | 17:02:32,650 ERROR [STDERR] at tal.noc.beans.NOCManagerService.run(NOCManagerService.java:86) | 17:02:32,650 ERROR [STDERR] at java.lang.Thread.run(Unknown Source) | This is my service: | @Service(objectName="jboss:custom=NOCManagerService") | public class NOCManagerService implements Runnable, NOCManagementService { | | .... | | public void run() { | this.running=true; | while(this.running) { | System.out.println("Awaken"); | Iterator nocs=this.loadNOCs().iterator(); | while(nocs.hasNext()) { | NOC noc = (NOC)nocs.next(); | try { | MessageSender ms=new MessageSender(); | ms.sendMessage("NOC: " + noc.toString(), "queue/msgQueue"); | } catch (Exception e) { | e.printStackTrace(System.out); | } | } | try { | MessageSender ms=new MessageSender(); | ms.sendMessage("NOC", "queue/msgQueue"); | } catch (Exception e) { | e.printStackTrace(System.out); | } | try { | synchronized (this) { | wait(60*1000); | } | } catch (Exception e) { | e.printStackTrace(System.out); | } | } | } | The service implements the following interface, just in case it makes any difference | @Management | public interface NOCManagementService { | Thanks a lot.
