Well, I took your bundle and deleted what I had to to get it to compile
(e.g., your upnp stuff) and it still sort of works for me except your
listener gets an NPE since it is trying to get the objectClass property
using the name "description":

There is something going wrong in your setup. Are you sure your
monitoring bundle is getting activated? Did you specify
Bundle-Activator in your manifest?
I created a bundle like yours and it worked fine for me:
g! lb

yes, I can install the related 'client bundle' and call the
service on the
server bundle:
ServiceReference sr =
context.getServiceReference(upnp.class.getName());
if(sr != null)
{
upnp x = (upnp)context.getService(sr);
if(x != null)
{
System.out.println("Vai chamar o serviço
HelloToYou...");
int n=x.GetNumber();
System.out.println("Vai libertar serviço
HelloToYou... "+n);
context.ungetService(sr);
This code from related 'client' bundle works.
I also checked the export packages of the used server bundle
and both
interface and bundle are marked for exportation

Hi
I am trying to play with service events in a client
bundle in order to be
notified when other bundles are registered.
So, I created a simple maven osgi bundler just with an
activator class.
public class Activator implements BundleActivator,
ServiceListener
{
public void start(BundleContext context) throws
Exception
{
System.out.println("Client bundle
initializing on start
method...");
context.addServiceListener(**this);
public void stop(BundleContext context) throws
Exception
{
context.removeServiceListener(**this);
}
public void serviceChanged(ServiceEvent event)
{
System.out.println("**serviceChanged called");
}
Then, in the gogo shell of felix I installed this
client bundle and
started
it. Then I installed other (server) bundle and started
it but the
serviceChanged handler is never called. Why?
Thanks a lot
Alex
