JPA - defining multi-column unique constraints

Is it possible using JPA to define multiple unique constraints.

@Entityclass Foo {    long id;     String name;     MyEnum type;}

Foo.id should be unique as should combinations of {Foo.name, Foo.type}.
Ex.
id, name, type
1, "name1", "type1"
2, "name1", "type2"
3, "name1", "type1" // error duplicate of id = 1

How do I achieve this using JPA annotations?

Thanks
