Hi Mauricio,

The into-array worked fine !

Thanks,
MH

> [1 2 3]

> If you don't already have a sequence (the vector in the previous example)

>
> user> (defn as-list [& args] (java.util.Arrays/asList (into-array args)))
>  #'user/as-list
> user> (as-list 1 2 3)
> [1 2 3]
> user> (type (as-list 1 2 3))
> java.util.Arrays$ArrayList
