How to access child element using @XmlElement with Hibernate

I have a table:

table:

    id

    name

    phone-area

    phone-number

This XML

<person>

    ...



    <phone>

        <area>111</area>

        <number>123-4567</number>

    </phone>



</person>

and this code:

@XmlRootElement(name="person")

@XmlAccessorType(XmlAccessType.FIELD)

@Entity

@Table(name = "person", schema = "test")

public class UserLinkedIn {

    @Id

    @GeneratedValue(strategy=GenerationType.IDENTITY)

    int id;

    // ...



    @XmlElement(name = "area")

    @XmlElementWrapper(name="phone")

    @Column(name = "phone-area")

    double area; 



    @XmlElement(name = "number")

    @XmlElementWrapper(name="phone")

    @Column(name = "phone-number")

    double number;

}

But when I run it i get this error:

com.sun.xml.internal.bind.v2.runtime.IllegalAnnotationsException: 1 counts of IllegalAnnotationExceptions

@XmlElementWrapper is only allowed on a collection property but "com.myproject.user.person" is not a collection property.

    this problem is related to the following location:

        at @javax.xml.bind.annotation.XmlElementWrapper(namespace=##default, name=phone, required=false, nillable=false)

I thought the "wrapper" annotation will take care of the wrapper element to get the child value. Am i missing something?

** I cannot change the schema nor the xml file.

I found the solution

I had to create another class "phone" and map the values to each elements

so in my main class:

@Transient

@XmlElement(name = "phone")

private Phone phone;

Then in my new class

@XmlRootElement(name = "phone")

static class Phone {

    @XmlElement(name = "area")

    @Column(name = "area")

    int area;

    @XmlElement(name = "number")

    @Column(name = "number")

    int number;



    // here area = 111

    // pnumber = 123-4567

}
