Hi BJ
SO i checked my configuration:
My packages are not exporting "org.osgi.service.event" packages so i
really do not understan why the Event Handler Tracker cannot see my
services...
With OSGi console i checked the package with the pacakages command this
is the reult:
org.osgi.service.event;
version="1.2.0"<org.eclipse.osgi.services_3.2.0.v20090306-1900 [74]>
org.eclipse.equinox.app_1.2.0.v20090306-1900 [41] imports
org.eclipse.equinox.cm_1.0.100.v20090306-1900 [42] imports
org.eclipse.equinox.event_1.1.100.v20090306-1900 [47] imports
org.eclipse.equinox.log_1.1.100.v20090306-1900 [57] imports
org.eclipse.equinox.useradmin_1.1.100.v20090306-1900 [68] imports
org.eclipse.equinox.wireadmin_1.0.100.v20090306-1900 [70] imports
org.spagic3.core_1.0.0 [88] imports
org.spagic3.deployer_1.0.0 [89] imports
As you see the version of org.osgi.service.event exported is 1.2.0 and
it seems this is used both by
"org.eclipse.equinox.event_1.1.100.v20090306-1900"
and by mine bundles so i really do not understand where's the problem.
What'is strange is that in my bundle called "org.spagic3.core_1.0.0
[88]" i've my abstract class tha implement the EventHandler interface,
but the real component class, and the component factory are in another
bundle that is not listed beacuse it's not importing the
"org.osgi.service.event" package.
I'll try to import the package in the bundle defining the real component
class... and let you know.
Thank for the help..

There is a possibility that org.osgi.service.event packages is
exported twice (or that your bundle has a private copy of that package).
If your bundle registers (or has DS register) the service using one
copy of the package and the Event Admin bundle is using another copy
of the package, then the Event Admin bundle cannot use your service
since it is not compatible.
Does your bundle import the org.osgi.service.event package from the
same place as the Event Admin bundle? If your bundle only exports the
package or simply has a private copy of the package, then the Event
Admin bundle will never see your service since the framework will
detect that both bundles are not sharing the same
org.osgi.service.event package.

Hi Miguel,
Sorry, i've made a typo error when copyng the xml file on this message.
The file is ok, and i just debug the code that DS code ( equinox ) that
create the component and register the services, and
it seems there's no error in ds implmentation.
By the way the EventHandlerTracker is not tracking the services just
registered in
the registry by ds.
I think i'll go in detailed debug of the EventHandlerTracker looking why
it's not working.
