Converting an XML to a JAXB Annotated Class

Question

I'm trying to convert the XML below into a JAXB annotated class but I'm having trouble thinking of a solution where an element repeats within an XML root.

   <addresses xmlns='http://jabber.org/protocol/address'>
       <address type='to' jid='hildjj@jabber.org/Work' />
       <address type='cc' jid='jer@jabber.org/Home' />
   </addresses>

I have this class that maps to the XML, I want an element 'address' with attributes 'type' and 'jid' to form within the XML Root Element 'addresses' for each item in the list that I pass in the constructor.

@XmlRootElement(name = "addresses", namespace = "http://jabber.org/protocol/address")
@XmlAccessorType(XmlAccessType.FIELD)
public class Addresses {

    @XmlElement
    private List<String> address;

    private Addresses() {
        // Private no-args default constructor for JAXB.
    }

    public Addresses(List<String> address) {
        this.address = address;
    }
}

For example, if I pass a list ("User1", "User2", "User3") when instantiating the object, the resulting XML will look like:

   <addresses xmlns='http://jabber.org/protocol/address'>
       <address type='to' jid='User1' />
       <address type='to' jid='User2' />
       <address type='to' jid='User3' />
   </addresses>

I managed to achieve this by creating two classes Address and Addresses. The Addresses root element will take a list of class 'Address' as the element input.

@XmlRootElement(name = "addresses", namespace = "http://jabber.org/protocol/address")
@XmlAccessorType(XmlAccessType.FIELD)
public class Addresses {

    @XmlElement
    private List<Address> address; //List of type address

    private Addresses() {
        // Private no-args default constructor for JAXB.
    }

    public Addresses(List<String> address) {
        this.address = address;
    }
}

This is the address class with the attributes 'to' and 'jid'. It takes an input jid of type String in the constructor.

@XmlRootElement(name = "address")
@XmlAccessorType(XmlAccessType.FIELD)
public class Address {

    @XmlAttribute
    private String to = 'to';

    @XmlAttribute
    private String jid;

    private Address() {
        // Private no-args default constructor for JAXB.
    }

    public Address(String jid) {
        this.jid = jid;
    }
}
