Malo by pomôct( nastavit( *dynamic-insert="true"* a *dynamic-update="true"*.

Nejako takto:
*<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
        "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
        "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd";>
<hibernate-mapping>

Ahoj.

Sorry ze zase otravujem, ale toto mi vrta v hlave:

        EntityManagerFactory fact =
Persistence.createEntityManagerFactory("testPU");

         EntityManager m = fact.createEntityManager();
         m.getTransaction().begin();

         E e1 = new E();
         e1.setA("a");
         e1.setB("b");
         e1.setC("c");
         e1.setD("d");
         m.persist(e1);

         m.getTransaction().commit();

//:: vola "insert into E (id, a, b, c, d) values (null, ?, ?, ?, ?)"

         m.getTransaction().begin();

         e1.setB("2");
         //m.merge(e1);

         m.getTransaction().commit();

//:: vola  "update E set a=?, b=?, c=?, d=? where id=?"

         m.close();

Ten update je kravina, preco nevola jednoducho
"update E set b=? where id=?"

Zle som niekde nieco nastavil?
