Problem with store procedures and Hibernate

Question

I got some problem when I am trying to override INSERT, and UPDATE operations in Hibernate. My delete functions works fine, and everything works when i´m not override with my stored procedure, and I have no idea why. When I am trying to make an INSERT, everything seems to be fine but no data is being insert and no excpetion throws.
When I am trying to make an UPDATE following excpetion throws:
Could not synchronize database state with session
org.hibernate.exception.GenericJDBCException: could not update: [labb6Hibernate.bil#18]
Here is my hbm.xml file:
<hibernate-mapping>
<class catalog="Cars" name="labb6Hibernate.bil" table="Bil">
<id name="idNum" type="java.lang.Integer">
<column name="idNum"/>
<generator class="identity"/>
</id>
<property name="marke" type="string">
<column length="10" name="Marke" not-null="true"/>
</property>
<property name="modell" type="string">
<column length="10" name="Modell" not-null="true"/>
</property>
<property name="arsmodell" type="string">
<column length="4" name="Arsmodell" not-null="true"/>
</property>
<sql-insert callable="true"> { call insertCars(?,?,?) } </sql-insert>
<sql-update callable="true"> { call updateCars(?,?,?) </sql-update>
<sql-delete callable="true"> { call deleteCars(?) } </sql-delete>
</class>
Here is my UPDATE code:
Session session = MyHibernateUtil.getSessionFactory().openSession();
session.beginTransaction();
int s = Integer.parseInt(idTxt.getText());
bil Bil = (bil) session.get(bil.class, s);
Bil.setIdNum(s);
Bil.setMarke(markeTxt.getText());
Bil.setModell(modellTxt.getText());
Bil.setArsmodell(arsmodellTxt.getText());
session.update(Bil);
session.getTransaction().commit();
session.close();
Here is my INSERT code:
Session session = MyHibernateUtil.getSessionFactory().openSession();
session.beginTransaction();
bil Bil = new bil();
Bil.setMarke(markeTxt.getText());
Bil.setModell(modellTxt.getText());
Bil.setArsmodell(arsmodellTxt.getText());
session.save(Bil);
session.getTransaction().commit();
session.close();
Does anyone have an idea what is wrong in my code?
