How to generate end tag for empty element in XML using JAXB

Question

I am creating XML using JAXB. But JAXB generates an empty tag that closes it itself. But my client needs a separate empty tag. I know that both are equal, but he does not agree with me. please anyone suggest a solution. Thanks.

Code example:

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "", propOrder = {
    "currencyCode",
    "discountValue",
    "setPrice",
    "spendLowerThreshold",
    "spendUpperThreshold",
    "discountApportionmentPercent",
    "discountApportionmentValue"
})
@XmlRootElement(name = "countryData")
public class CountryData {
    protected String currencyCode;
    protected String discountValue = "";
    protected String setPrice = "";
    protected String spendLowerThreshold = "";
    protected String spendUpperThreshold = "";
    protected String discountApportionmentPercent = "";
    protected String discountApportionmentValue = "";

    // Setters and Gettres
}

Actual output:

<currencyCode>GBP</currencyCode>
<discountValue/>
<setPrice/>
<spendLowerThreshold/>
<spendUpperThreshold/>
<discountApportionmentPercent>0.0</discountApportionmentPercent>
<discountApportionmentValue/>

Expected Result:

<currencyCode>GBP</currencyCode>
<discountValue></discountValue>
<setPrice></setPrice>
<spendLowerThreshold></spendLowerThreshold>
<spendUpperThreshold></spendUpperThreshold>
<discountApportionmentPercent>0.0</discountApportionmentPercent>
<discountApportionmentValue></discountApportionmentValue>

Code for sorting:

try {
    Marshaller marshaller = JAXBContext.newInstance(CountryData.class).createMarshaller();
    ByteArrayOutputStream os = new ByteArrayOutputStream();
    marshaller.marshal(countryData , os);
    log.debug("The PPV request raw XML -> " + os.toString());
} catch (JAXBException e) {
    // nothing to do
}

I am using JDK 6.0

If you created classes from XSD , then you would also create an ObjectFactory class. If you can not find here on how to create an ObjectFactory class.

JAXBContext context;
            context = JAXBContext.newInstance(*yourClass*.class);

final ObjectFactory objFactory = new ObjectFactory();

            final JAXBElement<YourClass> element = objFactory
                    .*autoGeneratedmethodfromObjectFactorytogetelement*;

Marshaller marshaller;
            marshaller = context.createMarshaller();

            marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT,
                    Boolean.TRUE);
            final StringWriter stringWriter = new StringWriter();


            marshaller.marshal(element, stringWriter);
          String message = stringWriter.toString();

The problem is resolved to force close the closing tag, just add an empty string as the value of this tag! You can do this using @XmlValue:

public class closedTag {

    @XmlValue
    private String content;


    public closedTag() {
        this.content = "";
    }

}
