Hi friends,
I want to persist a Region Object. Region Object contains a Map also.
When I do the session.save(region), the data is only gets inserted for region table not for the map table.

The mapping file is below. Can anyone help me on the same.

Hibernate version:3.0

Mapping documents:
<hibernate-mapping>
<class name="kh.doc.ejb.impl.Region" table="REGION">
<id name="id">
<column name="REGION_ID" length="50"/>
<generator class="assigned"/>
</id>
<map name="map" inverse="true">
<key column="REGION_ID"/>
<index column="Language" type="string"/>
<element type ="string" column = "Name" />
</map>
</class>
</hibernate-mapping>

Invocation Code
************************************************************
Region region = new Region();

region.setId(7);
HashMap name = new HashMap();
name.put("EN","MALASIYA");
region.setMap(name);
new RegionDAO().persistRegion(region);

*************************************************************
DAO
*************************************************************
public final class RegionDAO {
private static final SessionFactory sessionFactory;

// Member variable: remember Hibernate session
private Session mSession;

static {
try {
// Create the SessionFactory from hibernate.cfg.xml
sessionFactory = new Configuration().configure().buildSessionFactory();
} catch (Throwable ex) {
// Make sure you log the exception, as it might be swallowed
System.err.println("Initial SessionFactory creation failed." + ex);
throw new ExceptionInInitializerError(ex);
}
}
public RegionDAO() {
mSession = sessionFactory.openSession();
}


public void persistRegion(Region region){

mSession.flush();
mSession.save(region);

}
}
*************************************************************
Region POJO


public class Region {

protected int id;
public Map map = new HashMap();

/**
* @roseuid 45127D7E0394
*/
public Region() {

}

/**
* Access method for the id property.
*
* @return the current value of the id property
*/
public int getId() {
return id;
}

/**
* Sets the value of the id property.
*
* @param aId the new value of the id property
*/
public void setId(int aId) {
id = aId;
}


/**
* Access method for the map property.
*
* @return the current value of the map property
*/
public Map getMap() {
return map;
}

/**
* Sets the value of the map property.
*
* @param aMap the new value of the map property
*/
public void setMap(Map aMap) {
map = aMap;
}

}

You are missing the cascade attribute on the <map> mapping, as explained here:

http://www.hibernate.org/hib_docs/v3/re ... ns-mapping

If you use <map cascade="save-update" ...> all inserts and updates will be propagated

Cascading is implicit on collections of value types. Without the code it's impossible to say what the problem here is.

Oh, I didn't see the code. Probably because it's not in code tags. Don't have time right now to read through that garbled mess.

Remove the inverse attribute on the set. You are asking Hibernate to ignore that side of the mapping , which is probably why its not inserting records into the join table.
Refer to the Hibernate reference docs Section 1.3.6. Working bi-directional links
