How to create element and set custom attribute to map a simple type class property

@XmlRootElement(name="flowPane")
public class Image implements Serializable {
    public  String name;
    public  String description;
}

Bound to 

<flowPane>
    <label text="name"/>
    <label text="description"/>
</flowPane>

Tried simply placing @XmlAttribute and @XmlElement annotations on the name and description properties but neither is the solution that I'm looking for.

Using Standard JAXB APIs

In order to get the same element to appear multiple times in an XML document you are going to need a List property. Note in the example below label will have a property mapped to the text attribute.

@XmlRootElement(name="flowPanel")
@XmlAccessorType(XmlAccessType.FIELD)
public class Image implements Serializable {

   @XmlElement(name="label").
   private List<Label> labels;

}

@XmlPath extension in EclipseLink JAXB (MOXy)

If you are using EclipseLink MOXy as your JAXB (JSR-222) provider then you could leverage the @XmlPath extension we added for this use case.

@XmlRootElement(name="flowPane")
public class Image implements Serializable {
    @XmlPath("label[1]/@text")
    public  String name;

    @XmlPath("label[1]/@text")
    public  String description;
}

You must wrap the fields with a new class

@XmlRootElement(name="flowPanel")
public class Image implements Serializable {

    public static class Label {
        @XmlAttribute()
        public String text;

        public Label(){}

        public Label(String text) {
            this.text = text;
        }   
    }

    @XmlElement(name="label")
    public Label name;
    @XmlElement(name="label")
    public Label description;    
}
