I have created pojo classes for Film and Image.

Film.java

public class Film {
    private String film_id;
    private String title;
    private String description;
    private String length;
    private String image_id;
    private Image image;
//setter and getter methods
}

Image.java

public class Image {
    private int image_id;
    private String name;
    private int size;
    private String type;
    private byte[] content;
//setter and getter methods
}

Please help I am new to this and I should use JAXB.

SOLUTION:

I have added

@XmlRootElement(name = "film")
public class Film {
    private int film_id;
    private String title;
    private String description;
    private int length;
    private int image_id;
    private Image image;
}

on the getter method of Image, I have added @XMLElement(name="image").

On Image class I have added an annotation @XmlRootElement(name = "image"), which gives me what I wanted.

Answer 1

The only thing required to get your use case to work is to add an @XmlRootElement annotation on the Film class:

import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement(name="Film")
public class Film {
    private String film_id;
    private String title;
    private String description;
    private String length;
    private String image_id;
    private Image image;
}

The Other Part of Your Solution

on the getter method of Image, I have added @XMLElement(name="image").

On Image class I have added an annotation @XmlRootElement(name = "image"), which gives me what I wanted.

Neither of these steps are required to map your particular use case.

Answer 2

Try converting your arrays to list on dublicating classes (worked for me)

As i see byte[] -> List < Byte>
