Struts2 xwork Type Conversion - Multiple different parameters into one Object

Is it possible to convert different paremeters into one object on your action?

Say from my html form, I pa开发者_StackOverflowss in variables, "firstname", "lastname". Can I write a type converter that will convert those into a Person object on my action?

I didn't see any examples of this, and I don't see API. I don't see how I can access the value stack in the StrutsTypeConverter to get to the other variables.

Thanks!

Example :

// JavaBeans
public class Person {
    @Getter @Setter private String firstname;
    @Getter @Setter private String lastname;
}

// Action
@Setter private Person person;

// form
<s:form>
  <s:textfield name="person.firstname" />
  <s:textfield name="person.lastname" />
</s:form>
