You can use nameObject(...) on the OzoneInterace to do name objects. Read the 
users guide about factories and you'll seen that there are better ways as 
well ;)...

Assuming an Auto object has a constructor like the foillowing:
public AutoImpl(String foo, int i)

An Auto is created as follows:

auto = (Auto)db.createObject( "AutoImpl",
                    OzoneInterface.Public,
                    "auto",
                    "String|int",
                    new Object[] {"bla", new Integer(123)}
            );

> or the method...
>
> createObject(java.lang.Class type, int access, java.lang.String
> objName, java.lang.Class[] sig, java.lang.Object[] args)

auto = (Auto)db.createObject( AutoImpl.class,
                    OzoneInterface.Public,
                    "auto",
                    new Class[] {String.class, int.class},
                    new Object[] {"bla", new Integer(123)}
            );

See the Users guide for a more thourough explanation.
