Http 204 error in REST web service (Jersey) -

i using jersey/java develop rest services. need return xml representation carstore :

 @xmlrootelement public class carstore {  private list<car> cars;   public list<car> getcars() {   return cars;  }  public void setcars(list<car> cars) {   this.cars = cars;  } 

here car object :

@xmlrootelement > public class car {  private string carname;  private specs carspecs;  private category carcategory;  public string getcarname() {   return carname;  }  public void setcarname(string carname) {   this.carname = carname;  }  public specs getcarspecs() {   return carspecs;  }  public void setcarspecs(specs carspecs) {   this.carspecs = carspecs;  }  public category getcarcategory() {   return carcategory;  }  public void setcarcategory(category carcategory) {   this.carcategory = carcategory;  }  } 

specs , category enums :

    @xmlrootelement > public enum category {   sedans, compacts, wagons, hatch_hybrids, suvs, convertibles, comparable; } 

my resource class :

    @get  @produces({mediatype.application_xml})  public carstore getcars()  {     return carstoremodel.instance.getallcars();  } 

my jersey client :

webresource service = client.resource(getbaseuri()); system.out.println(service.path("rest").path("cars").accept( mediatype.application_xml).get(string.class)); 

i getting http 204 error on access alongwith client exception :

com.sun.jersey.api.client.uniforminterfaceexception

any ideas ? !

edit : have yet not developed model class...i initialized car objects dummy data , put them in carstore. showing classes here clumsy. btw, sorry writing 204 error..it getting exception led me think so.

i believe getting uniforminterfaceexception because getcars() function not returning http response body. root problem car list isn't being converted xml jaxb because missing @xmlelement annotation.

your getcars() function should be:

@get @produces(mediatype.application_xml) public carstore getcars() {     // mycarstore instance of carstore             return mycarstore.getcars(); } 

and car list in carstore should defined:

@xmlelement(name="car") private list<car> cars;
