NoClassDefFoundError: org / eclipse / persistence / internal / oxm / mappings / Field

Я создаю код Java, который создает XML динамически на основе схемы XML.Я использую Jaxb для этого.Вот мой код: 

public class Testing2 {
    private static void traverseProps(DynamicJAXBContext c, DynamicEntity e, DynamicType t, int level) throws DynamicException, InstantiationException, IllegalAccessException{
        if (t!=null) {
           // logger.info(indent(level) + "type [" + t.getName() + "] of class [" + t.getClassName() + "] has " + t.getNumberOfProperties() + " props");
            for (String pName:t.getPropertiesNames()){
                Class<?> clazz = t.getPropertyType(pName);
              //  logger.info(indent(level) + "prop [" + pName + "] in type: " + clazz);
                //logger.info("prop [" + pName + "] in entity: " + e.get(pName));

                if (clazz==null){
                    // need to create an instance of object
                    String updatedClassName = pName.substring(0, 1).toUpperCase() + pName.substring(1);
              //      logger.info(indent(level) + "Creating new type instance for " + pName + " using following class name: " + updatedClassName );
                    DynamicType child = c.getDynamicType("generated." + updatedClassName);
                    DynamicEntity childEntity = child.newDynamicEntity();
                    e.set(pName, childEntity);
                    traverseProps(c, childEntity, child, level+1);
                } else {
                    // just set empty value
                    e.set(pName, clazz.newInstance());
                }
            }
        } else {
          //  logger.warn("type is null");
        }
    }

    public static void main(String[] args) throws FileNotFoundException, JAXBException, DynamicException, InstantiationException, IllegalAccessException {
        // TODO Auto-generated method stub
        String PATH_TO_XSD = "C:/.....XSD.xsd";

        String YOUR_ROOT_TYPE = "Doc";
        InputStream in = new FileInputStream(PATH_TO_XSD);
        DynamicJAXBContext jaxbContext = DynamicJAXBContextFactory.createContextFromXSD(in, null, Thread.currentThread().getContextClassLoader(), null);
        DynamicType rootType = jaxbContext.getDynamicType(YOUR_ROOT_TYPE);
        DynamicEntity root = rootType.newDynamicEntity();
        traverseProps(jaxbContext, root, rootType, 0);
    }

}

Я получаю ошибку ниже, хотя я добавил jars: jaxb-xjc-2.2.11.jar и jaxb-core-2.3.0.jar.Может кто-нибудь помочь мне в отладке проблемы:
