any one using iBatis on lunarpage?
I get this error:

2008-11-17 23:51:57,138 ERROR [MYSITE_PATH] :   
--- The error occurred in PATH_TO_XML_FILE 
--- The error occurred while applying a result map. 
--- Check the getPlaceNameStr-AutoResultMap. 
--- Check the result mapping for the 'name' property. 
--- Cause: java.lang.IllegalArgumentException: null source

The XML query is:
   <select id="getPlaceNameStr" resultClass="java.lang.String">
      SELECT name
      FROM place
      WHERE placeid=17
   </select>

The DB setup is a table called place with the column "name" set up as varchar(64) and it is not null for the placeid=17

Any ideas on how to begin tracing or similar issues using ibatis? I am using ibatis-2.3.4.726.jar and put it in the web-inf/lib directory. I am also using mysql-connector-java-5.1.7-bin.jar and put it in the same directory. Any packages I am missing?

Your help and experience is greatly appreciated.
Thanks
