Hi all, at first, CDI + CODI is really cool stuff for building a webapp.
1) Our Environment: We are using OWB 1.1.3, CODI 1.0.2 on a Tomcat 7 environment with CODI @Transactional. Database Producer: @PersistenceContext(unitName = "myunit") private EntityManager extendedEntityManager; @Produces @ConversationScoped @MyQualifier public ExtendedEntityManager createExtendedEntityManager() { return new ExtendedEntityManager(this.extendedEntityManager); } public void dispose(@Disposes @Siemens ExtendedEntityManager extendedEntityManager) { if (extendedEntityManager.isOpen()) { extendedEntityManager.close(); } } -DatabaseService which gets above EntityManager injected -OtherServices which getting the database Service injected 2) The Problem: Using Quartz, Seam Cron or the following class, which creates a thread, leads into the same problem. @ApplicationScoped public class ApplicationTimer { @Inject private Log log; @Inject private OtherService otherService; // gets databaseService injected, databaseService gets EntityManager injected public void init() { log.info("initialize timer thread"); try { otherService.doSomething(); // WORKS in Context of this ApplicationScoped bean } catch (Exception e) { log.error(e); } Thread timer = new Thread() { public void run() { while (true) { log.info("That's the thread"); try { otherService.doSomething(); // EXCEPTION occurs in Child Thread Thread.sleep(5000); } catch (Exception e) { log.error(e); } } } }; timer.start(); } } An exception javax.enterprise.context.ContextNotActiveException: WebBeans context with scope type annotation @ConversationScoped does not exist within current thread occurs We also tried to start a (javax) Conversation. Leads into the same Excpetion with ... a @RequestScoped does not exist. The child thread is not in context of a web request, we guess the EntityManager have to (as descriped in CODI doc). But how to solve this problem? Is there a possibility to create/provide an appropriate context to the child thread or to start scheduled services in another way? Best Regards Erwin
