The File.java is a simple bean that has 2 properties a string and a DataHandler, the DataHandler is used to receive the file contents sent from the consumer of the web service.

• Since the File.java is transfered between the consumer and the web service it needs to be serialized and sent in xml format. The @XmlType and @XmlMimeType("application/octet-stream") annotations define that. When sending binary content between a web service, we can make use of the DataHandler and the @XmlMimeType("application/octet-stream") annotation to receive that. cxf automatically takes care of creating the underlying transports and formats.
