Re: [virgo-dev] Virgo and ECF remote services

Hi Hristo,

Hi Scott,

Virgo has no problems resolving or deploying the equinox.common bundle. These operations are working as expected.

As you perhaps already saw [1] the bundle has lazy activation policy which causes confusion since its status is reported as LAZY. This status appears to be (thanks to Glyn for the explanation) a subset of STARTING. According to the specification this is the expected behavior until the bundle is activated by class loading.

The issue for which I created bug 333174 is that removal of the equinox.common bundle triggers a stop, which fails (as expected) if the bundle did not reach STARTED. There is no real problem here since the removal is ok as well.

So in short - no tricks should be needed to have equinox.common (or ECF) running with Virgo. Of course if you have some questions or issues running ECF in Virgo please come back to us - we'll be glad to help :)

I guess I still don't understand (since I haven't experienced it myself), why folks like Peter [1] are having trouble with getting ECF+equinox common running on Virgo.  Do you think it's likely some consequence of 333147?  Should I direct Peter and other folks over to this mailing list for assistance on these issues?

BTW...I'm finishing up the ECF impl of the OSGi Remote Service Admin spec and am keen on using it on Virgo also.  Does Virgo currently distribute the OSGi remote service admin classes?  (i.e. org.osgi.service.remoteserviceadmin.*).

Hi Virgoers,

I work on the ECF project [1].  We have an implementation of OSGi 4.2 remote services [2], and we're now finishing up an implementation of the OSGi 4.2 remote services admin spec [3] for release in late Feb 2011.

Recently, we've had several folks in our consumer community (e.g. [4]) that have asked about using ECF remote services along with Virgo.  As far as I/we can tell, this should be eminently doable, as Neil Bartlett has successfully run ECF remote services (along with dependencies) on Felix [5].

However, some reports from users (e.g. [4]) have been that the Virgo runtime does not resolve the org.eclipse.equinox.common bundle.  We have some dependencies on classes that are exposed by equinox.common (as well as some other equinox APIs...like jobs API...and concurrent API...and extension registry), but these can/should/do run just fine inside of other OSGi frameworks.

Is there some 'trick' to running equinox.common and some other equinox pieces in Virgo that we can notify our/your users about?  It would be quite nice for both our user communities if the ECF remote services and remote services admin were to run easily inside of Virgo...and it seems to me this should be doable.  But perhaps I'm missing something.

Thanksinadvance for any information.
