how to use new scala 2.8.0 nested annotations

问题

looks like when scala 2.8.0 is out, we can use nested @annotations in our persistence layers. But how? Can anyone please transform this from java to scala? Thanks.

@NamedQueries({
    @NamedQuery(name = "findAll", query="select p from Person p"),
    @NamedQuery(name = "findTheOne",
          query="select p from Person p where p.name = 'Neo'")
})

You have to wrap the elements in an Array() and write the nested annotations like a constructor call:

@NamedQueries(Array(
    new NamedQuery(name = "findAll", query="select p from Person p"),
    new NamedQuery(name = "findTheOne",
          query="select p from Person p where p.name = 'Neo'")
))
