server-side prepared

I just can't use server-side prepared statements
Here is a snippet of my sources, note that the column I'm inserting is
of "bigint" data type
PreparedStatement prep = Connection.prepareStatement("insert into
tablename values (?)");
prep.setNull(1, Types.BIGINT);
prep.executeUpdate();
For some strange reasons when I execute that I get the following
error: "Column 'cpf' is of type BIGINT, but expression is of type text"
Well, I specified the BIGINT type correctly, What can I do?
