I think your only problem here is that you're short an argument. If
you want to call a function with varargs, you must provide an array
that contains them. If you don't want any arguments, you still have to
pass the empty array.
ie: (.queryForObject jdbcTemplate rowMapper (make-array Object 0))
Side note, it might actually be easier to use the overload that takes
a map as its final parameter, you could just use a normal clojure {}
in that case.
