Hibernate JPA funguje! Na webu se zobrazuje seznam cílů načtený z databáze: JSP → Webová beana → EJB → JPA → Hibernate → PostgreSQL
Jen pozor na správné typy: typ v mapovacím .hbm.xml souboru musí odpovídat typu v databázi, jinak by se aplikace ani nedeploynula
a zároveň musíme mít stejný typ v DTO – jinak aplikace padá (při otevření stránky).
