Hi Friends,

My Code is returning multiple Database related Exception on Query [any one of them each time]

Exceptions are

Caused by: javax.persistence.PersistenceException: org.hibernate.exception.GenericJDBCException: Cannot release connection

Caused by: javax.persistence.PersistenceException: org.hibernate.SessionException: Session is closed!

Caused by: javax.persistence.PersistenceException: org.hibernate.exception.JDBCConnectionException: could not execute query

Caused by: java.lang.IllegalStateException: EntityManager is closed


My Class file is

Code:

@Name("SystemHealthStatus")
@Scope(ScopeType.APPLICATION)
@AutoCreate
public class SystemHealthStatusDao implements Serializable {
   
   @In
   EntityManager em;

   @SuppressWarnings("unchecked")
   public List<SystemHealthStatus> getAll() {
      return em.createQuery("from SystemHealthStatus").getResultList();  ///// ALL ERRORS ARE COMING ON THIS LINE
   }
}


Errors are
