dependent object - deepCopy()?

[Tim Drury]

I have an EJB, Contact, and a dependent object, Address.
I have the deployment descriptor setup using the <dependents>
and <relationships> area (based on another user's post).

When I deploy, Orion throws this message at me:

Error Compiling file <...>: The dependent class tfc.Address
should implement a "public abstract tfc.Address deepCopy()
method"

How do I implement this?  Where is the documentation on
this method?

I tried:

public Address deepCopy()
{
   Address a = new Address(this.street1, this.street2, ....);
   return a;
}

but I still got the same error upon deployment.

Any ideas?
