Hi,
I'm facing strange Eclipselink behavior with my web application that is running on Tomcat 6.0.26
There is a method which gets data from MS SQL Server 2000. This method throws an exception after several succesfull calling (5-7).
Can anybody help?
Thanks
public List<Expedice> getExpediceList() {
EntityManagerFactory emf = Persistence.createEntityManagerFactory("metroPU");
EntityManager em = emf.createEntityManager();
Query q = em.createQuery("select e from Expedice e order by e.datum desc");
q.setHint(QueryHints.REFRESH, "true");
expediceList = q.getResultList();
em.close();
emf.close();
return expediceList;
}
