resultClass for BLOB field

[Karen Koch]

Hello --

I think this is a simple one:  What is the proper resultClass to use when 
returning only a single column (of BLOB type) as the result of a statement?  
SqlMaps doesn't seem to like "BLOB".

 <select id="getEncryptedPassword" resultClass=??? parameterClass="string">
        SELECT Password FROM EPLoginAccount WHERE EmailAddr = #value#
 </select>

Thanks!
