in(...) clause and PreparedStatement

Hi all.
    It may be stupid question, but is there way to use PreparedStatement
with queries like
SELECT * FROM mytable WHERE t_id IN (1,2,3) ?
    I've googled but haven't found nothing explicitly said on this topic.
    I've tried the following
    PreparedStatement st = conn.prepareStatement("SELECT * FROM mytable
WHERE t_id IN ( ? )");
    st.setObject(1,"1,2,3");

    and get error complaining on type mismatch.

    Thanks in advance, Sergey.
