Hello I'm running resin 4.0.13, on linux debian/sun jdk. I have some cron jobs launched by resin.xml configuration <scheduled-task>. They work perfectly on my macosx (they are launched every minute for testing purpose). On the production server some cron jobs work all right while others have a strange error ; java.lang.IllegalStateException: Attempting to execute an operation on a closed EntityManager. at org.eclipse.persistence.internal.jpa.EntityManagerImpl.verifyOpen(EntityManagerImpl.java:1563) at org.eclipse.persistence.internal.jpa.EJBQueryImpl.getResultList(EJBQueryImpl.java:693) at realty.Globalaction.reload_orgtables(Globalaction.java:947) at reacron.Cleancache.CleanOrgCache(Cleancache.java:33) at reacron.Cleancache.run(Cleancache.java:23) at com.caucho.server.util.ScheduledThreadPool$TaskFuture.run(ScheduledThreadPool.java:591) at com.caucho.env.thread.ResinThread.runTasks(ResinThread.java:182) at com.caucho.env.thread.ResinThread.run(ResinThread.java:126) This is the code at Globalaction.java:947 Query qr=m_manager.createQuery("select on from OrgNetwork on"); List<OrgNetwork> lst=(List<OrgNetwork>)qr.getResultList(); <=== this line is 947 I suspect that at night time there is no particular activity on the server, but why other cron jobs work all right ? m_manager is created by the resin.xml conf : <ejb-server data-source="realty/jdbc" create-database-schema="false"/> I wonder why it is "closed" sometimes. I even don't know how to close it. Thanks for any help. --
