osgi: Using ServiceFactories?

Question

I\'m currently trying to get a simple bundle containing a Service Factory running.

This is my factory class:

public class SvcFactory implements Servi         


        

Answer 1

It is actually rather simple ... DS creates an instance for each bundle, so with DS you do not implement Service Factory, DS does all the hard work. For example:

@Service(serviceFactory=true) 
public class MyServiceFactory implements XyzService {

   ...
   @Activate
   void activate(ComponentContext ctx) {
      System.out.println("Using bundle: " + ctx.getUsingBundle());
   }
}

Every time another bundle gets this XyzService, DS will create a new instance. You can use the ComponentContext (optionally passed in the activate method) to get the bundle that is using you.
