Question

In my iPOJO application i try to bind a service to two consumers:

Consumers:

@Component(immediate = true)
@Instantiate(name = "com.example.consumerX")
@Provides
public class consumerX{
    @Requires(id="ms",optional=true)
    private MyService[] services;

    @Bind(id = "ms", aggregate = true, optional = true)
    public synchronized void register(MyService service) {
            System.out.println("service bind to consumer");
    }

    @Unbind(id = "ms")
    public synchronized void unregister(MyService service) {
            System.out.println("service unbind from consumer");
    }
}

Services:

@Component(immediate = true)
@Instantiate(name = "com.example.serviceX")
@Provides(specifications = { MyService.class, MyServiceX.class})
public class MyServiceX{
    ...
}

If I start consumerA, consumerB and serviceA, the service binds only to consumerA. If I start consumerB and serviceA, the service binds to consumerB.

Is it possible to let the services bind to both consumers? Is there an annotation for it?

Thanks.

Answer 1

It is definitely possible for a service to be used by several consumers. Your code looks good, and so it should work.

Did you try to check the current state using the ‘instances’ command (http://felix.apache.org/site/ipojo-arch-command.html) ?
