Question

我是OSGi世界的新手。我使用Felix 5.0.1作为OSGi容器和Apache Aries Blueprint捆绑集。 Maven 3.2.1，Eclipse版本：作为IDE的Juno Service Release 2。 Windows 7专业版操作系统。

我使用OSGi包开发了两个小应用程序。

欢迎申请，它有3个捆绑
- welcomeapi bundle
- welcomeserver bundle
- welcomeclient bundle
api包有接口，服务器包正在实现接口并暴露服务。

客户端软件包引用/使用服务器软件包公开的软件包。

此应用程序运行正常，并且希望系统输出正在Felix命令提示符
联系申请

此应用程序还有3个包
- ContactAPI
- 的ContactDAO
- ContactHellowWorld
在这个应用程序中，我做了一些额外的事情，如下所示。
- ContactAPI
  
  bundle有一个接口和一个类。（并没有任何config.xml）
- ContactDAO：
  
  此捆绑包具有API /方法，将Contactid作为输入参数，连接到数据库并获取所需的数据，如fname，lname等。并向请求者提供这些联系方式（即ContactHelloWorld包）。
- ContactHellowWorld
  
  bundle有API /方法，它们将Contactid作为ContactDAO方法的输入参数提供，并且应该获取联系对象并在控制台上打印值。
简而言之，ContactHelloworld包调用ContactDAO项目API /方法 contactDAO.getContactList（）; contactDAO.getContact（101）;

所有三个Contact应用程序包都已安装并处于活动状态但没有输出

在Felix控制台上获取以下日志语句（日志级别设置为4）

    DEBUG: WIRE: [Contact_DAO [43](R 43.0)] osgi.ee; (&(osgi.ee=JavaSE)(version=1.7)) -> [org.apache.felix.framework [0](R 0)]

但是为什么我在欢迎申请中没有得到同样的问题？

请查看随附的代码。任何帮助将不胜感激。

One more important point I have to mentioned 
I observed that the services for the Contact application are not getting registered. (Even though Contact Application bundles are Active)

   41|Active     |    1|spring-osgi-io (1.2.1)
   42|Active     |    1|WelcomeApi (0.0.1.SNAPSHOT)

OSGi包已在Felix中安装并处于活动状态，但没有期望或可见的输出
