Hi,
I'm developping an rcp application. I've several questions:
-When I run my product, the org.eclipse.osgi framework is launch, if I
understand correctly it's the implementation of the OSGI specifications?
-How can I access to services of the framework? For example I want to get
the LogReaderService, which should be started with the framework? But I
don't konw if this interface is implemented in equinox... If not how can I
do it and register this service?
Thanks for you help, if you have some samples it would be apreciated...

Gervais,
- Yes, "org.eclipse.osgi" is the system bundle that implements the
framework.
- Services of the framework are accessed the same as any other services
(because they ARE the same). The nicest way to do this is with Declarative
Services. The lower-level way is to use a ServiceTracker, eg:
ServiceTracker logReaderTracker = new ServiceTracker(context,
LogReaderService.class.getName(), null);
logReaderTracker.open();
// Later...
LogReaderService logReader = (LogReaderService)
logReaderTracker.getService();
if(logReader != null) {
// Do something with logReader
}
// Later still...
logReaderTracker.close();
- LogService and LogReaderService are implemented in Equinox by the
"org.eclipse.equinox.log" bundle. If you start that bundle, then you will
get a LogService and a LogReaderService that you can use. If you don't,
then you won't.
Kind regards

Hi Alex,
Thanks again for your answer...
I've downloaded the bundle and what I don't understand is my plugin A is
dependents of org.eclipse.equinox.log, and when plug A is started,
apparently the log bundle is not... When I launch my application with
eclipse and an Equinox OSGI configuration this
bundle(org.eclipse.equinox.log) is started, why it's not started with a
simple Eclipse configuraton. I've noted that the org.eclipse.equinox.log
doesn't have Eclipse-LazyStart: true... Is there an impact? It means that
the bundle should start at the begining?
Thanks again and sorry for this stupid quesiton.

Reason: Missing Constraint: Import-Package: org.osgi.service.cm;
version="1.2.0", and I don't know how to fix it, moreover, this service logs
only bundle event, but I don't see log posted from the Ilog interface, so my
question is what's the link between LogService, and the Interface Ilog
implemented by Plugin, if there is one.
Thanks.

Mickael,
It sounds like the "org.eclipse.osgi.services" bundle is not installed.
That bundle contains the interfaces (but NOT the implementations) of each
of the services in the OSGi compendium, including the LogService and
LogReaderService.
Regarding your earlier question, your plugin "A" does not need a
dependency on org.eclipse.equinox.log, in fact it shouldn't have such a
dependency. It should only have an Import-Package on the
"org.osgi.service.log" package.
The way to get a bundle to start is not to create a dependency on it, and
Eclipse-LazyStart is also irrelevant here. To ensure that the log bundle
is started each time by the platform, you need to add it to the
osgi.bundles property in config.ini - as you later discovered.
Regards
Neil
