SOAP response wraps objects into <return>, and not the class name

I'm creating SOAP service using CODE FIRST approach. All the XML is auto generated by IntelliJ, and then deployed on GlassFish with genereated WAR. I have base entity Mesage declared like this:

@XmlRootElement
@XmlType(propOrder={"id", "content", "created", "author"})
public class Message {
    private long id;
    private String content;
    private Date created;
    private String author;

    public Message() {
        this.created = new Date();
    }
    public Message(long id, String content, String author) {
        this.id = id;
        this.content = content;
        this.created = new Date();
        this.author = author;
    }
    @XmlElement
    public long getId() {
        return id;
    }
    public void setId(long id) {
        this.id = id;
    }
    @XmlElement
    public String getContent() {
        return content;
    }
    public void setContent(String content) {
        this.content = content;
    }
    @XmlElement
    public Date getCreated() {
        return created;
    }
    private void setCreated(Date created) {
        this.created = created;
    }
    @XmlElement
    public String getAuthor() {
        return author;
    }
    public void setAuthor(String author) {
        this.author = author;
    }
}

In App marshalling with JAXB return an object like this:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<message>
    <id>1</id>
    <content>Content</content>
    <created>2018-12-05T20:58:18.012+01:00</created>
    <author>Author</author>
</message>

But when i retrieve a message through service, it wraps it up in the return markup, like its not an class object:

<?xml version="1.0" encoding="UTF-8"?><S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
    <SOAP-ENV:Header/>
    <S:Body xmlns:ns2="http://service/">
        <ns2:getMessageResponse>
            <return>
                <id>1</id>
                <content>dada</content>
                <created>2018-12-05T20:45:23.043+01:00</created>
                <author>Kamil Kot</author>
            </return>
        </ns2:getMessageResponse>
    </S:Body>
</S:Envelope>

I think Im missing something about bindings, and I dont know how to make JAXB consider my class as a ComplexType. I have been searching the solution for hours, and I still cant find it. Once again id like to make IntelliJ generate it right way, as i want to stay away from making changes to WSDL itself. I would really appreaciate any help with that.
