Method

Tread(File file, Class typeParameterClass)
Reads an XML file and returns the content as an object of the specified class. 
T content = null;
try {
    JAXBContext jaxbContext = JAXBContext.newInstance(typeParameterClass);
    Unmarshaller jaxbUnmarshaller = jaxbContext.createUnmarshaller();
    content = (T) jaxbUnmarshaller.unmarshal(file);
} catch (JAXBException e) {
    e.printStackTrace();
return content;
StringreadComplexProperty(String name, List objects, String methodName)
read Complex Property 
for (Object o : objects) {
    if (o instanceof JAXBElement) {
        JAXBElement element = (JAXBElement) o;
        if (name.equals(element.getName().getLocalPart())) {
            return callMethod(element.getValue(), methodName);
return null;
ObjectreadExternal(InputStream inputStream, Class clazz)
Reads the InputStream of JAXB marshaled xml and creates an object of the given Class 
Object object = null;
try {
    JAXBContext context = JAXBContext.newInstance(clazz);
    Unmarshaller unmarshaller = context.createUnmarshaller();
    object = (Object) unmarshaller.unmarshal(inputStream);
} catch (Exception e) {
    e.printStackTrace();
return object;
TreadJAXB(Class clazz, InputStream is)
read JAXB
