but didn't work. Would you please tell me what I did wrong? I wrote a class:

@Component
//Declaring that all it will handle all requests starting by /TestCaseDto
@Path("query")
public class QueryApi {
    @Path("/helloworld")
    @GET
    @Produces({MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON})

        return new String("Hello World!!!");
    }
}

and I

Answer 1

A little more detail about this "dint work" would be nice
for starters- try changing your path above your class name like this

@Path("/query")

Answer 2

I think in here you return string. so you can't give produce type as xml ,Try this

@Stateless
@Path("query")
public class QueryApi {
   @Path("/helloworld")
   @GET
   @Produces({MediaType.APPLICATION_JSON})
   public String test(){
     return new String("Hello World!!!");
   }
}
