OSGi unsatisfied dependency even though dependency is available - Equinox

[dustin_dustin.schultz]

Hi,

I have a strange problem that only occurs with Equinox. Felix does not have this problem.

I have a bundle that exports a service:

karaf@root> ls 279

further-mdr-ws (279) provides:
------------------------------
org.springframework.osgi.bean.name = mdrAssetServiceRestClient
Bundle-SymbolicName = edu.utah.further.mdr.ws
Bundle-Version = 1.1.0.SNAPSHOT
objectClass = edu.utah.further.mdr.ws.api.service.rest.AssetServiceRest
service.id = 547
karaf@root> 

And then I have a bundle that imports that service:

<osgi:reference id="mdrAssetServiceRestClient"
     interface="edu.utah.further.mdr.ws.api.service.rest.AssetServiceRest" />

However, the bundle is always in a waiting state:

[ 300] [Active     ] [            ] [Waiting] [   60] further-ds-impl (1.1.0.SNAPSHOT)

The logs show it is waiting for the service that is available:

14:45:09,521 | INFO  | xtenderThread-76 | DependencyServiceManager         | 85 - org.springframework.osgi.extender - 1.2.1 | OsgiBundleXmlApplicationContext(bundle=edu.utah.further.ds.impl, config=META-INF/spring/*-all.xml) is waiting for unsatisfied dependencies [[&mdrAssetServiceRestClient]]

I've also verified that the importing bundle has the interface imported

karaf@root> imports 300
...
further-mdr-ws-api (278): edu.utah.further.mdr.ws.api.service.rest; version="1.1.0.SNAPSHOT"
...

Again, this only happens with Equinox and not Felix. What else could prevent it from being resolved?

Thanks,

Dustin

Ok, shortly thereafter posting this I figured out the issue on my own. It appears that Equinox requires that you also import that package which has the implementation of said exported interface. Once I added that to the imports, everything started right away.
