unexpected element (uri:"", local:"Group"). Expected elements are <{}group>

Meet an exception when unmarshalling from xml

JAXBContext jc = JAXBContext.newInstance(Group.class); 
Unmarshaller unmarshaller = jc.createUnmarshaller();
Group group = (User)unmarshaller.unmarshal(new File("group.xml"));

Group class has no any annotation and group.xml just contains data.

Anything can be the cause?

It looks like your XML document has the root element "Group" instead of "group". You can:

  1. Change the root element on your XML to be "group"
  2. Add the annotation @XmlRootElement(name="Group") to the Group classs.
