我已经创建了一个SOAP服务，该WS端点正在接受String并返回枚举值。返回枚举值时，它抛出错误以下。 我不确定为什么即使我从WS服务方法返回枚举值，它也会引发Nullpointer异常。

这是服务端点代码：
@WebService
@SOAPBinding(style = Style.DOCUMENT, use = Use.LITERAL)
public class HelloServiceImpl {
@WebMethod
public EmployeeType enumReturn(@WebParam(name="arg0")String arg0){
System.out.println("enum opoeration method called:"+arg0);
System.out.println("enum value:"+EmployeeType.PERMANENT);
return EmployeeType.PERMANENT;
}
}
枚举文件：
@XmlRootElement(name = "employeeType", namespace = "http://soapresource.learn.com/")
@XmlAccessorType(XmlAccessType.FIELD)
@XmlEnum ( value = String.class )
//@XmlType(name = "employeeType", namespace = "http://soapresource.learn.com/")
public enum EmployeeType implements Serializable{
@XmlEnumValue(value = "TEMPORARY") TEMPORARY("TEMPORARY"),
@XmlEnumValue(value = "PERMANENT") PERMANENT("PERMANENT");
@XmlElement( name = "employeeType", namespace = "" )
private String empType;
EmployeeType(String str){
empType = str;
}
public String getEmpType(){
System.out.println("enum file get called");
return empType;
}
}
