NOTE: The code work completely fine on my Eclipse. But when I try to run on command prompt, it throws and exception

注意：代码在我的 Eclipse 上完全正常。但是当我尝试在命令提示符下运行时，它会抛出异常

When create the JAXBContextfrom classes you need to include the ObjectFactoryclass in the classes passed in to create the JAXBContext.

创建JAXBContextfrom 类时，您需要将该ObjectFactory类包含在传入的类中以创建JAXBContext.

JAXBContext jaxbContext = JAXBContext.newInstance(BMWebgateConf.class, ObjectFactory.class);

If your model is generated from an XML schema then I would recommend creating the JAXBContexton the package name:

如果您的模型是从 XML 模式生成的，那么我建议JAXBContext在包名称上创建：

JAXBContext jaxbContext = JAXBContext.newInstance("com.javavids.jaxb.sitemap");
