Hi all
i'm beginners, i have to do a sort by a fiel in a nested class...i'll explain better.
I've a class Node wich have a subclass Category with the following configuration

...
@ManyToMany(cascade={CascadeType.PERSIST, CascadeType.MERGE})
@JoinTable(
name="category_node",
joinColumns={@JoinColumn(name="nodeId")},
inverseJoinColumns={@JoinColumn(name="categoryId")}
)
public Set<Category> getCategories() {
return categories;
}
...

i extract some nodes and i have to order by 'name', a field of Category class.
What can i do?i create the Order criteria but i don't know what 'fieldName' i have to use

...
Order.asc(fieldName);
...

Sorry for my english, thanks
