OSGi bundle is installed and active in Felix but no desire or visible output - apache

Question

I am new to OSGi world.
I am using Felix 5.0.1 as OSGi container and Apache Aries Blueprint bundle set.
Maven 3.2.1 , Eclipse Version: Juno Service Release 2 as IDE. windows 7 Pro OS.
I have develop two small application using OSGi bundles.
Welcome application it has 3 bundles
welcomeapi bundle
welcomeserver bundle
welcomeclient bundle
The api bundle is having interface , server bundle is implementing the interface and exposing the service.
Client bundle is referring/consuming the bundle expose by the server bundle.
This application works fine and desire sys outs are getting properly displayed on Felix command prompt
Contact application
This application also has 3 bundles
ContactAPI
ContactDAO
ContactHellowWorld
In this application I have done some additional things which are as follows.
ContactAPI
bundle has one interface and one class. (and NOT having any config.xml)
ContactDAO:
This bundle has API/methods that will take Contactid as input argument , connect to database and fetches the required data such as fname, lname etc.
and provide these contact details to requester(i.e. ContactHelloWorld bundle).
ContactHellowWorld
bundle has API/methods that will provide Contactid as input argument to the methods of ContactDAO and should get the contact object and print the values on console.
In short the ContactHelloworld bundle invokes ContactDAO projects API/methods
contactDAO.getContactList();
contactDAO.getContact(101);
All three bundles of Contact application are installed and are in active state but no output

On the Felix console getting this following log statements (log level is set to 4)
DEBUG: WIRE: [Contact_DAO [43](R 43.0)] osgi.ee; (&(osgi.ee=JavaSE)(version=1.7)) -> [org.apache.felix.framework [0](R 0)]
But then Why I am not getting the same issue in the welcome application ?
Please have a look at the attached code.
Any Help will be appreciated.
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)
