It is easier then you think!

</resultMap>

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

should work!

Assume I have something like the following:

public class Name {

    String firstName;

    String lastName;

    // getter & setter for both

}

public class Person {

    String ssn;

    Name name;

    // getter & setter for both

}

And assume I have a table PERSON with columns SSN, FNAME, LNAME

I want to map creating Person objects but I get hung up with the "name" member object that is composed of two of the columns in the table. I'm writing something like this but it does not work:

    <resultMap id="namemap" class="Name">
        <result property="firstName" column="FNAME"/>
        <result property="firstName" column="LNAME">
    </resultMap>

    <resultMap id="personmap" class="Person">
        <result property="SSN" column="ssn"/>
        <result property="name" column="{FNAME, LNAME}" resultMap="namemap"/>

The last line is where I am stuck. I don't want to reference a statement since I already have the field I want. How do I get the two columns to be composed into the "name" property?

Thanks.
