This worked for me, when serializing a class where I couldn't use annotations (LogRecord):

            JAXBContext jc = JAXBContext.newInstance(LogRecord.class);
            JAXBElement je = new JAXBElement<>(new QName("log"), LogRecord.class, record);
            Marshaller marshaller = jc.createMarshaller();
            marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
            marshaller.setAdapter(new XmlAdapter() {
                @Override
                public String marshal(String v) throws Exception {
                    if(null == v || v.length() == 0) {
                        return null;
                    }
                    return v;
                }
                @Override
                public String unmarshal(String v) throws Exception {
                    return v;
                }
            });
            ByteArrayOutputStream xml = new ByteArrayOutputStream();
            marshaller.marshal(je, xml);
