Hi all,

I have a class X (say) which has a Collection/Map which is supposed to contain objects of class Y. Now class Y has a Collection/Map which is supposed to contain object of class Z. I am giving the dummy code below.

public class X
{
private Map = ymap; // This Map contains object of class Y
public X
{
ymap = new HashMap();
}
public Map getYmap()
{
return this.ymap;
}
public void setYmap(Map map)
{
this.ymap = map;
}

}

public class Y
{
private Map = zmap; // This Map contains object of class Z
public Y
{
zmap = new HashMap();
}
public Map getZmap()
{
return this.zmap;
}
public void setZmap(Map map)
{
this.zmap = map;
}

}
public class Z
{
// Contains its own properties
}

My requirement is..when I save object X, I want the contained Y and Z objects to be persisted simultaneously.Can this be done in Hibernate? If possible pls let me know what shold be the .hbm file for the data structure mentioned above.


With thanks
