Spring Composite Applications
Is it possible to build a Spring DM bundle that composes one or more Spring components packaged as standard jars built via Maven?
For instance, build a (non-OSGI bundle) service.date.jar, with the following context:
<context:component-scan base-package="service.date"/>
Then build an app.osgi.date.jar bundle that contains a dependency on service.date.jar. It has the following context:
<import resource="classpath*:service.date.context.xml"/>
<osgi:service id="dateService"
ref="dateService"
interface="service.date.DateService"/>
The packaged app.osgi.date.jar, an OSGi bundle, contains the service.date.jar, a standard jar. The bundle plugin configuration is:
<Export-Package>
service.date.*;version=${version}
</Export-Package>
<Include-Resource>
src/main/resources
</Include-Resource>
<Embed-Dependency>
*;scope=compile|runtime
</Embed-Dependency>
Running an AbstractConfigurableBundleCreatorTests integration test, though, produces the following exception:
Caused by: org.osgi.framework.BundleException: The bundle could not be resolved. Reason: Missing Constraint: Import-Package: service.date; version="0.0.0"
Overriding getTestBundlesName(), per the Spring DM documentations, does not resolve the above exception.
Also the above import of the service.date.context.xml is not processed, according to the log.
This leads me to believe that one 'can not' build a Spring DM bundle that imports and autowires together a set of Spring components packaged as standard jars. Is this true?

All the required jars are on the classpath. The issue is that the Spring DM context ignores the import of 3 other Spring contexts. So I'm unable to launch a Spring application composed of a set of contexts.
Using only one context works, less the integration test. But that is not ideal in a component-based world.
Has no one else attempted to build a Spring DM bundle that compose other Spring contexts? It works like a charm in standalone and web applications.
I would respectfully suggest that the next release of Spring DM include meaningful example applications.
