I need to update our backup database server when I am writing to our current database server.

So I am using two Entity Managers to handle this and pass the same Entity.

em.persist(dmvActivity);
em.flush();

// write to HotSite DB
emTml.persist(dmvActivity);
emTml.flush();


This worked fine, till I made the entity cacheable. Now I get the following error :


javax.ejb.EJBException: javax.persistence.PersistenceException: org.hibernate.PersistentObjectException: detached entity passed to persist: com.cp.mvr.common.ejb.persistence.DmvColor


Further, if an entity is set as cacheable, everytime when you do a findAll does the cache get refreshed from the database?

Thanks,
Peter.
