I have the following classes

public class AuthorizationContext {
private int id;
private Action action;
private SubAction subAction; }

mapped to the following classes
<many-to-one name="action" class="Action" column="ACTION_CODE_ID" not-null="true" lazy="false" cascade="none"/>
<many-to-one name="sub" class="SubAction" column="SUBACTION_CODE_ID" not-null="true" lazy="false" cascade="none"/>


public class Action {
private int id;
private String name; }

public class SubAction {
private int id;
private String name; }

The problem is that the business wants our trading partners to pass in the Action and Sub Action names to our web service. I want to avoid doing a lookup every request to get the ActionId and SubActionId. Is there any way to map this relationship, or do I have to do the lookup? Based on this, I don't really see the value in having an Action and SubAction table?

Thanks,
