You do not have to map a Map as a parameter. Just tell iBatis that the
parameter is a map and use the key-names you used to populate it in your
update (note: use parameterClass instead of parameterMap).
Map s1 = new HashMap();
s1.put("code", "001");
s1.put("description", "Region Transaction upd");
s1.put("fiscalYear", "2005");
s1.put("id", "1501");
client.update("updateSector", s1);
<update id="updateSector" parameterClass="map">
UPDATE SECTOR SET SECTOR_DESC = #description# WHERE SECTOR_ID = #id#
</update>
That's all there is to it.
