DS Annotations with BND

[Jens Kübler]

I'm trying to create the most simple example with ds annotations.

I have a component with annotations and I am writing to sysout "Hello World"

@Component(name="test")

public class DockerIdentification implements ContainerIdentification {

@Activate

public void activate() {

System.out.println("Hello World");

}

}

I managed the run configuration and checked that the xml file is generated correctly in the jar.

Everthing is fine but I simply don't see "Hello World" when running with felix

What could I possible do wrong ?

I figured that in the component's bundle bnd.bnd there is a drop down box for annotations that always resets itself to Manually.

As the bundle looks fine I suspect this is just a UI bug.

Couple of things spring to mind:

1. Is anything actually triggering that component to be instantiated?
It's not marked as @Component(immediate=true).

2. Do you have the right SCR bundles installed? You need at least
org.apache.felix.scr installed before any DS components will do
anything.

Here is the console output. Added immediate = true

Oh and one more thing. Launching it in debug mode and setting breakpoints eclipse never enters these breakpoints

In the launch I have

-runrequires.debug:  ${debug-bundles}

-runtrace: true

What triggers the component to be activated? Since it is not immediate, does some other bundle get its service?

D'oh. I could not see the forrest through the trees.

It does work now.

Thanks for the help.
