I want to use jaxb annotations with existing java classes to create above XML input but i don't know how create nested xml structure based on Java classes

Answer 1

Try this:

@XmlRootElement
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(propOrder = {"contract", "order"})
public class Info {
@XmlElement(required = true)
private Contract contract;
@XmlElement(required = true)
private Order order; // Getters and setters
}

Another class:

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(propOrder = {"symbol", "sectype", "exchange", "currency"})
public class Contract {
@XmlElement(required = true)
private String symbol;
@XmlElement(required = true)
private String sectype;
@XmlElement(required = true)
private String exchange;
@XmlElement(required = true)
private String currency;

//Getters and setters
}

Create an order class the same way.
