Question

I am working on Rest web services and producing JSON data for mobile app.I am using Jersey 1.4, web server as tomcat 7, Hibernate 3.3,MySQL5.
I am new to REST world.
I have an endpoint which simply returns a list of year based on my query.

Output:

{“success”:true,”count”:2,”message”:null,”data”:[{“year”:2012},{“year”:2013}]}

which is fine what I expected.

But I have been asked to include a description value of type string with this return json data set. Based on value of year.

If year=2012(current year) description should be “this year”, for year=2013 description =”next year”, for year= 2011 description=”previous year” ,for year=2010 description=”2010″ and so on.

What I have to return is something like:
{“success”:true,”count”:2,”message”:null,”data”:[{“year”:2012,”description”:”this year”},{“year”:2013,”description”:”next year”}]

My resource class

 @GET
@Path("/{countryCd}/upcoming")
@Produces("application/json")
public  JResponse<JsonResponse> getYearsForUpcoming(@PathParam("countryCd") 
     String  countryCode) {

     JobDao jobDao =new JobDao();   
     JsonResponse res= new JsonResponse();


   @SuppressWarnings({ })
List<Jobs> jobList=  jobDao.getYearsForUpcoming(countryCode);
   if(jobList==null){
       throw new NotFoundException("Error occured! NO data found");
   }

    int count = jobList.size();
    res.setCount(count);
    res.setData(jobList);

           return JResponse.ok(res).build();

}

my query

String sql=”SELECT distinct year(s_date) as year from jobs where country=:countryCode and year(s_date)>=year(curdate()) order by year(s_date) asc”;
Query query=session.createSQLQuery(sql).addScalar(“year”).setResultTransformer(Transformers.ALIAS_TO_ENTITY_MAP);
query.setParameter(“countryCode”, countryCode);
upcomingRegattaList= query.list();

Jobs.java ( myeclipse generated entity for table jobs )

public class Jobs implements java.io.Serializable {

private static final long serialVersionUID = 1L;
private Integer jobId;
private String status;
    private Date  SDate;
    //some more

    // getter and setters

}

I am clueless how to add a new attribute to my JSON data which is not in my entity.
Any idea greatly appreciated.

Thanks in advance

You have probably to create one more entity to map your new object that will be something like

public class Data {
    private String year;
    private String description;
}

then load a list of this entities and add them to the response.
