Hi All, Although its not very critical but I would like to be aware of the reason. if the class at server side has defind an attribute with xmlelement notation the generated class element is then of JAXBELEMENT. | @XmlElement(nillable=true) | protected String sessionID = null; | then the repectively generated class having attribute defined as | @XmlElementRef(name = "sessionID", type = JAXBElement.class) | protected JAXBElement<String> sessionID; | My question is , Notations are ok but why object is of type JAXBElement. If I remove @XmlElement(nillable=true) notation from server class, then created object is of simple java type, String. Any reason and clue to get simple java object while keeping the notation ?
