The Query object capsulates the formulated query itself, not the result of the query. In order to execute the query and retrieve the result, you have to call

query.list();

which returns a List of the selected properties (ie name in this case).

If your query returns a single result, there is a convenience method:

query.uniqueResult();

And if your query is an update statement, you can execute it without having any result:

query.executeUpdate();

(this last one returns the number of updated entities).
