How to parse xml element to primitive types?

I have this xml: 

<order>
    <id_address_delivery>4</id_address_delivery>
</order>

and java class

@JacksonXmlRootElement(localName = "order")
public static class Order
{
    @JacksonXmlProperty(localName = "id_address_delivery")
    public String id_address_delivery;
}

When I try to parse xml with code:

XmlMapper XmlMapper = new XmlMapper()
XmlMapper.readValue(xml, Order.class);

I getting the error : Can not deserialize instance of java.lang.String out of START_OBJECT token

How to correct deserialize xml element to primitive type?

EDIT: Could you confirm that the variable "cls" is Order.class? I get the error you reported if cls is String.class but that is not the correct approach as you are parsing the <order> element not the <id_address_delivery> element.

Do you have any bespoke configuration that might be causing the problem? Perhaps dodgy whitespace - try removing the whitespace completely?

My code ...

public class Jackson {

    @JacksonXmlRootElement(localName = "order")
    private static class Order
    {
        @JacksonXmlProperty(localName = "id_address_delivery")
        public String id_address_delivery;
    }

    public static void main(String[] args) throws IOException {

        XmlMapper mapper = new XmlMapper();
        Order order = mapper.readValue("<order>\n\t<id_address_delivery>4</id_address_delivery></order>", Order.class);

        System.out.println(ToStringBuilder.reflectionToString(order, ToStringStyle.JSON_STYLE));
    }
}

produces

{"id_address_delivery":"4"}
