在下面的链接里弄的，可是搞不出来啊。
IDE 是 Eclipse 4.4.1 + efxclipse + java 1.8.0.31
http://stackoverflow.com/questions/18594548/marshall-a-list-to-
原帖中的例子可以把XML文件unmarshal出来，可是我试图加一个marshal例子把数据写
成XML文件就不行。
后面是我的code, 不过和帖子中基本相同，只改了一点。

这里还有一个错误不知道如何修正
MyWrapperForList wrapper1 = new MyWrapperForList(
data);
//wrapper.setData(dataList.cList);
JAXBElement jaxbElement = new JAXBElement<>(
new QName("List"), MyWrapperForList.class, wrapper1);

// Marshalling and saving XML to the file.
m.marshal(jaxbElement, "src/unmar/nub1.xml");

这个是我搞错了，那个文件名应该是file，虽然可以unmarshal,但结果不是真正想要的
datalist,有点奇怪
这个教程的例子也不行。
