Premature end of file using JAXB and Unmarshaller. Xml from the answer, it suits me

I do not know what to do next. Everything seems right; input Output.

I create an xml file and send some service for verification.

Answer:

11:10:34,922 INFO  [STDOUT] printing out the input stream
<?xml version="1.0" encoding="UTF-8" standalone="yes"?><Response>
    <Method name="XML/Release/New" time="2013-04-23T15:10:35.1446238Z">
        <ResponseStatus>100</ResponseStatus>
    </Method>
</Response>
finished printing out the input stream
11:10:34,922 INFO  [STDOUT] got the unmarshaller
11:10:34,925 ERROR [PRNDataAccessUtil] Caught an error: javax.xml.bind.UnmarshalException
 - with linked exception: [org.xml.sax.SAXParseException: Premature end of file.] : null

The code:

try {
            out = connection.getOutputStream();
            ByteArrayOutputStream bos = PRNPostNewsReleaseUtil.createNewsReleaseXml(newsRelease);
            bos.writeTo(out);

            JAXBContext context = JAXBContext.newInstance(Response.class.getPackage().getName());
            in = connection.getInputStream();

            BufferedReader inp = new BufferedReader(new InputStreamReader(in));
            System.out.println("printing out the input stream");
            String line;
            while((line = inp.readLine()) != null) {
                System.out.println(line);
            }
            System.out.println("finished printing out the input stream");

            Unmarshaller unmarshaller = context.createUnmarshaller();
            response = (Response) unmarshaller.unmarshal(in);

        } catch (Exception ex) {
            log.error("Caught an error: " + ex + " : " + ex.getMessage());
            return null;
        } finally {
            if (null != in) connection.disconnect();
        }
