Following up on this
thread, I can't seem to the correct one-to-one mapping via hibernatedoclet: The error I got:
Quote:
net.sf.hibernate.MappingException: could not instantiate id generator

Caused by: net.sf.hibernate.MappingException:

Excerpt from the xdoclet tags between class Foo and Bar:
Code:
public class Foo {
/**
* @hibernate.id
* unsaved-value="null"
* generator-class="native"
* @return Long
*/
public Long getId() {
return id;
}
/**
* @hibernate.one-to-one
* class = "org.babi.Bar"
* cascade = "save-update"
*/
public Bar getBar() {
return bar;
}
---o<--snip----
}
public class Bar {
/**
* @hibernate.id
* unsaved-value="null"
* generator-class="foreign"
*
*/
public Long getId() {
return id;
}
/**
* @hibernate.one-to-one
* class = "org.babi.Foo"
* constrained = "true"
*/
public Foo getFoo() {
return foo;
}
---o<--snip----
}
What is the mistake ? Thanks.
