Unmarshalling XML JAXB with multiple elements same name

Question

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

Solution 1

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;
    }
}

Solution 2

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;
    ...
}
