The idea is to get one particular column value from active object table.

@GET
/*@Path("/{vals}")*/
/*@Produces({MediaType.APPLICATION_JSON, MediaType.APPLICATION_XML})*/
public Response getAllValues()
{
    List<DiscConf> confs =  actConfService.getAllVals();
    if(confs!=null)
    {
        return Response.ok(confs).type(MediaType.APPLICATION_JSON_TYPE).build();
        //return Response.ok(new LeangearsRestResourceModel(new GenericEntity<List<DiscConf>>(Lists.newArrayList(confs)))).build();
    }
    return Response.ok(new LeangearsRestResourceModel("NOT FOUND")).build();
}

But the code leads to:

    I think [this previous answer](https://stackoverflow.com/questions/21708339/avoid-jackson-serialization-on-non-fetched-lazy-objects) solves your problem. You cannot use JSON directly on ActiveObject classes, which is what the error `org.codehaus.jackson.map.JsonMappingException: No serializer found for class com.sun.proxy.$Proxy3736 and no properties discovered to create BeanSerializer (to avoid exception, disable SerializationConfig.Feature.FAIL_ON_EMPTY_BEANS)` is telling you. – Ken Y-N Jun 16 '15 at 23:58
  • Thanks ken. I did what was suggested there and now I can see the results but only in console – user2900150 Jun 17 '15 at 07:38
  • Object {value: "{"actors":["AO_F51DA7_PRODUCT_ACTOR_CONF {ID = 1}"…D = 2}","AO_F51DA7_PRODUCT_ACTOR_CONF {ID = 3}"]}"} – user2900150 Jun 17 '15 at 09:25
