The Greeter Service implementation bundle provides a trivial implementation of the GreeterService interface. Additionally, it has an Activator:
| Code Block | ||||
|---|---|---|---|---|
| ||||
public class Activator implements BundleActivator {
private ServiceRegistration registration;
public void start(BundleContext bc) throws Exception {
Dictionary props = new Hashtable();
props.put("osgiservice.remoteexported.interfaces", "*");
props.put("osgiservice.remoteexported.configuration.typeconfigs", "pojoorg.apache.cxf.ws");
props.put("osgiorg.remoteapache.configurationcxf.pojows.address", "http://localhost:9090/greeter");
registration = bc.registerService(GreeterService.class.getName(), new GreeterServiceImpl(), props);
}
public void stop(BundleContext bc) throws Exception {
registration.unregister();
}
} |
...
So the remote service is simply looked up the normal way, via the OSGi Service Registry.
How does it get there? The fact that a lookup on a service is done internally triggers a Service Registry Hook. This will go out to any registered Distributed OSGi Discovery implementations and query them for any matching services.
However, in our setup we haven't yet registered a Discovery implementation. There is an alternative, more static way to provide discovery type information, in case this info is not available via discovery. It can be specified in a OSGI-INF/remote-service/*.xml file. This the content of the Greeter Service Consumer remote-services.xml file:
| Code Block |
|---|
