How to wrap sublist with jaxb

Question

When trying to map a customer-> order 1:n relationship with jaxb 2.2.6 I\'d like to get the list of orders wrapped in a separate node \"orders\".

currently the result is

Answer 1

Instead of

/**
 * getter for orders
 * @return orders
 */
@XmlElement(name="orders", type=OrderJaxbDao.class)
public List<Order> getOrders() { return orders; };

You need

/**
 * getter for orders
 * @return orders
 */
@XmlElement(name="order", type=OrderJaxbDao.class)
@XmlElementWrapper(name="orders")
public List<Order> getOrders() { return orders; };

The @XmlElementWrapper name is the name of the wrapping element (orders) and the @XmlElement name is the name of the per-entry element inside the wrapper (order).

Answer 2

This seems to do the trick:

  @XmlElementWrapper(name="orders")
  @XmlElement(name="order", type=OrderJaxbDao.class)
  public List<Order> getOrders() { return orders; };

} // CustomerJaxbDao

Answer 3

It sounds like you want to wrap the Order in your CustomerJaxbDao class.

@XmlElementWrapper( name="orders" )
@XmlElement(name="order", type=OrderJaxbDao.class)
public List<Order> getOrders() { return orders; };

Might do what you want.
