how to use new scala 2.8.0 nested annotations

Question

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'")
})

Answer 1

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'")
))

Overfill

so one more problem emerged: for Stateless(name="Bean") Bean{...} I' ve got error: expected start of definition – Brume

@coubeatczech for top level annotations you cannot omit the '@'. I do not know the context of that error but did you mean to write @Stateless(name="Bean") class Bean { /* ... */ }? – Overfill

sorry, I wrote this without checking if the typed text corresponds the thought, and yes, I meant this: @Stateless(name="Bean") class Bean{...} – Brume

Well, I wasted my 1 hour figuring this out and then I found this. Works like charm! – Parashah
