org.eclipse.persistence.oxm.XMLUnmarshaller.unmarshal()
PUBLIC: Read and parse the XML document from the file and map the XML data into an object. The file must contain a valid XML document, and be mapped by a project used to create the XMLContext. The type of object returned will be based on the root element of the XML document. @param file The file to unmarshal from @return the object which resulted from unmarshalling the given file @throws XMLMarshalException if an error occurred during unmarshalling
