Answer 1

you need to tell the server that this webmethod will generate an xml output you can do that by adding this line,try by removing the class level produces tag

 @GET
 @Path("/hello/{personCode}")
 @Produces("application/xml") //added this line ,you can declare anything json/xml
 public Personel getPersonelByPersonCode(@PathParam("personCode") String personCode) {
     Personel personel = new Personel(personCode);
     return personel;
 }

you also need to annotate your Personnel class with xml tags like this

@XmlElement(name="nationalCode")
private String nationalCode;

@XmlElement(name="name")
private String name;

@XmlElement(name="lastName")
private String lastName;

@XmlElement(name="fatherName")
private String fatherName;

annotation can be skipped ,but it gives you power to customize tags (Eg "firstName" can be used as "fName" tag)

hope this helps!

Good luck!
