null entityManager in Quartz job
--------------------------------
Key: SEAMPERSIST-61
URL: https://issues.jboss.org/browse/SEAMPERSIST-61
Project: Seam Persistence
Issue Type: Bug
Affects Versions: 3.0.0.Final
Environment: jboss-as-7.0.0.Final
Java(TM) SE Runtime Environment (build 1.6.0_26-b03)
Linux omega 2.6.32-33-generic-pae #70-Ubuntu SMP Thu Jul 7 22:51:12 UTC 2011 i686
GNU/Linux
Reporter: JEE 4 Hire
When the QuartzInitializer starts, the entityManager is not null.
When the HelloJob executes, the entityManager is null.
Also, the instance of org.jboss.logging.Logger does not work inside HelloJob.
How can I get a valid handle to entityManager inside HelloJob?
Why exactly is it failing? Is it because the job is retrieved from the database when it is
run
by the quartz scheduler? In Seam 2, using @In EntityManager entityManager worked.
