Summary

0005263: entity-manager closed from scheduled-task

Description

(rep by Riccardo Cohen)

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.

org.eclipse.persistence.internal.jpa.EntityManagerImpl.verifyOpen(EntityManagerImpl.java:1563)

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 :

Â <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.
