Subject Re: How do I resultmap a composite member variable?
Date Thu, 22 Dec 2005 21:51:04 GMT
It is easier then you think!

<resultMap id="personmap" class="Person">
         <result property="SSN" column="ssn"/>
         <result property="name.firstName" column="FNAME"/>
	<result property="name.lastName" column="LNAME"/>
</resultMap>


I think you have to have have a no argument constructor for you  
Name.class

should work!
