import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;

//annotations

@Path("/mobileRepair")
public class Repair {

    @GET
    // getting query from user
    @Produces(MediaType.TEXT_XML)
    // Consumer request as XML
    public String sayHello() {
        String response = "<?xml version='1.0'><CustomerName><CustomerId>Hello Karthik</CustomerId></CustomerName>";
        return response;
    }
}
