Sling Servlet как услуга в CQ5 (комплект OSGi)

Question

Мы пытаемся создать серверную службу osgi для CQ5. Мы используем архетип cqblueprints с eclipse в качестве среды dev. И мы можем развернуть его на CQ с помощью консоли. В веб-консоли CQ можно просмотреть подробную информацию о расслоении в

Но, если я не искать в меню Услуги (в Феликсом консоли) ничего я мог бы найти, который я создал.

Это нормально? Чтобы убедиться в этом я упаковал Простой servelet

import java.io.IOException; 
import javax.servlet.ServletException; 
import org.apache.sling.api.SlingHttpServletRequest; 
import org.apache.sling.api.SlingHttpServletResponse; 
import org.apache.sling.api.servlets.SlingSafeMethodsServlet; 
import org.slf4j.Logger; 
org.slf4j.LoggerFactory; 

@Component(immediate = true, metatype = false) 
@Service(value = javax.servlet.Servlet.class) 
@Properties(value = { @Property(name = "sling.servlet.methods", value = { "GET" }), 
     @Property(name = "sling.servlet.paths", value = { "/path/to/my/servlet", "/apps/path/to/my/servlet" }) }) 
public class AbsoluteUrlServlet extends SlingSafeMethodsServlet { 
    private static final long serialVersionUID = -1920460619265757059L; 
    private static final Logger logger = LoggerFactory.getLogger(AbsoluteUrlServlet.class); 

    @Override 
    protected void doGet(SlingHttpServletRequest request, SlingHttpServletResponse response) throws ServletException, IOException { 
     logger.debug("AbsoluteUrlServlet::doGet()"); 
     response.setContentType("text/plain"); 
     response.getOutputStream().print("Hello AbsoluteUrlServlet World!"); 
    } 
} 

Но, когда я прошу сервлет из браузера,

http://localhost:4502/apps/path/to/my/servlet 

Я получаю следующее сообщение об ошибке. Нет ресурс не найден

Просьба предоставить некоторые указатели для решения этой проблемы.

Answer 1

И наконец, чтобы найти причину.

Я пропустил maven-scr-plugin в моем pom.xml из-за которой serviceComponents.xml отсутствовала в моей пачке. (См My previous thread)
