Send XML object through HTTP to a POST REST Service

I have an EJB application which needs to send a XML object to a RESTfull service through HTTP Post. (All in the same infrastructure park)

I have seen some examples which the XML object is converted to String before send it to the service. However, I want to pass all the XML object itself. (I suppose it's possible)

For instance, in a web application architecture, I would do that by using RestTemplate, as follow:

RestTemplate restTemplate = new RestTemplate();
EmployeeVO result = restTemplate.postForObject( uri, newEmployee, EmployeeVO.class);

Now, I strictly should do the same using HttpURLConnection instead.

Someone can help me by showing some example? The rest service only consumes "application/XML" and returns a String.

Follow my RESTfull signature and my XML object.

RESTFull Service

@RestController
@RequestMapping(value = "/analytic/")
public class AnalyticController {

    @RequestMapping(value = "/requestProcessor", method = RequestMethod.POST, consumes = MediaType.APPLICATION_XML_VALUE)
    public String analyticRequest(@RequestBody ServiceRequest serviceRequest){
        //Some code here...

        return "0";
    }

}

Domain

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

    /**
     * 
     */
    private static final long serialVersionUID = 1L;

    @XmlAttribute(name = "Method")
    private String method;

    @XmlElement(name = "Credential")
    private Credential credential;

    public String getMethod() {
        return method;
    }

    public void setMethod(String method) {
        this.method = method;
    }

    public Credential getCredential() {
        return credential;
    }

    public void setCredential(Credential credential) {
        this.credential = credential;
    }
}

Thanks in advance.

Thank you all for your thoughts!

I could solve my issue by doing the below code.

URL url = new URL("http://server:port/service_path");
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setDoOutput(true);
connection.setInstanceFollowRedirects(false);
connection.setRequestMethod("POST");
connection.setRequestProperty("Content-Type", "application/xml");

OutputStream os = connection.getOutputStream();

JAXBContext jaxbContext = JAXBContext.newInstance(MyClass.class);
jaxbContext.createMarshaller().marshal(MyClass, os);
os.flush();
