If you don't want to map a class to the outer most data element, below is how you could use StAX as per your original question.

import java.io.*;
import javax.xml.bind.*;
import javax.xml.stream.*;

public class Demo {

    public static void main(String[] args) throws Exception {
        XMLInputFactory xif = XMLInputFactory.newFactory();

        FileReader reader = new FileReader("input.xml");
        XMLStreamReader xsr = xif.createXMLStreamReader(reader);

        JAXBContext jc = JAXBContext.newInstance(Customer.class);
        Unmarshaller unmarshaller = jc.createUnmarshaller();

        while(xsr.hasNext()) {
            while(xsr.hasNext() && (!xsr.isStartElement() || !xsr.getLocalName().equals("customer"))) {

                xsr.next();
            }
            if(xsr.hasNext()) {
                Customer customer = (Customer) unmarshaller.unmarshal(xsr);
                System.out.println(customer);
            }
        }

    }

}
