Unmarshalling XML JAXB with multiple elements same name

I am trying to unmarshall an XML document that has multiple elements with the same name. I am not sure whether I need to create an Arraylist of my bean and pass it to the unmarshaller. I am hoping that somebody would give me some pointers to figure this out. The XML that I am trying to parse comes as a SOAP response but I stripped out the envelope so I only have teh body of it, it looks like this:

<return>
    <row>
        <fkdevice>bddc228e-4774-18b3-9c64-e218cbef7a8x</fkdevice>
    </row>
    <row>
        <fkdevice>74a5a260-bbd9-0491-7c58-0b1983180d2c</fkdevice>
    </row>
    <row>
        <fkdevice>312b5326-d7f1-4fb6-b1d9-dd96bb016152</fkdevice>
    </row>
    <row>
        <fkdevice>ed110481-e1e1-4659-ae09-1d23d888292b</fkdevice>
    </row>
</return>

This is returned from a table that has more than 50 fields, but I created a testBean and I defined fkdevice only just to make it simple my bean looks like this:

package beans;
//imports    

@XmlRootElement(name="return")
public class testBean {
   //I think I need an arraylist here because I have multiple elements with teh same name.
   public ArrayList<string> fkdevice;

   public ArrayList<String> getFkdevice(){
       return fkdevice;
   }

   public void setFkdevice(ArrayList<String> fkdevice){
       this.fkdevice = fkdevice;
   }
}

This gives me an error: 1 counts of IllegalAnnotationExceptions Class has two properties of the same name "fkdevice" and it points to the getter and setter.

Any info could be helpful, Thanks in advance

Maybe something like this:

@XmlRootElement(name="return")
public class returnBean {
   private ArrayList<Row> rows;

   public ArrayList<Row> getRows(){
       return rows;
   }

   public void setRows(ArrayList<Row> rows){
       this.rows = rows;
   }
}

Notice the field is private now.

And then you probably don't need annotation here:

public class Row {
    private String fkdevice;

    public String getFkdevice() {
        return fkdevice;
    }

    public void setFkdevice(String val) {
        fkdevice = val;
    }
}

Your field and method are both public. By default, JAXB binds every public field and every getter/setter pair.

One solution is to use @XmlAccessorType to specify that fields and only fields are bound to XML. 

@XmlRootElement(name="return")
@XmlAccessorType( XmlAccessType.FIELD )
public class testBean {

    @XmlElement( name="fkdevice" )
    public ArrayList<string> fkdevice;
    ...
}
