- The Greeter Interface bundle
- The Greeter Service Implementation bundle
- The Greeter Service Consumer bundle
The Greeter Interface bundle exports the GreeterService interface which both other bundles depend on. This is the interface:
| Code Block | ||||
|---|---|---|---|---|
| ||||
public interface GreeterService { Map<GreetingPhrase, String> greetMe(String name); GreetingPhrase [] greetMe(GreeterData name) throws GreeterException; } |
The GreetingPhase and GreeterException classes are also defined by this bundle.
In this walkthrough, the following setup will be used:
The client side bundles will be running in Equinox, invoking on a Distributed OSGi Service running in Felix. Note that the choice of containers is completely trivial. Any OSGi container that implements the Service Registry Hooks (a new feature in OSGi 4.2) can be used on either side.
...
Let's run the server in Felix 1.8.0. As a prerequisite it requires some of the OSGi Compendium Specification interfaces. These don't come with the Felix download, but you can install a bundle that contains these interfaces straight from the Felix download areaMaven.
In this walkthrough I'm using the single-bundle distribution of CXF/DOSGi which can be installed straight from the Maven release repository.

Now let's start up the server-side greeter bundles. Like with the DOSGi bundle itself, I'm installing these straight from the Maven release repository.
