[equinox-dev] Service component deployment fails into a running Equinox application

Hello Guys,

I have an Equinox OSGi application using Declarative Services with 3 plugins:
-a service interface plugin
-a service provider component
-a service consumer component (cardinality: 0..n, policy: dynamic)

Framework is launched.
id State Bundle
0 ACTIVE org.eclipse.osgi_3.8.0.v20110908-1857
3 ACTIVE osgi.example.service.consumer_1.0.0.qualifier
4 ACTIVE org.eclipse.osgi.services_3.3.0.v20110711-1243
5 ACTIVE org.eclipse.equinox.util_1.0.300.v20110502
6 ACTIVE org.eclipse.equinox.ds_1.3.100.v20110705
10 ACTIVE osgi.example.service_interface_1.0.0.qualifier
11 ACTIVE osgi.example.service.implementation_1.0.0.qualifier

In case the application is launched, the service consumer is triggered.

But in case the service provider is installed and started only after the application has launched, SCR fails to load service implementation class. See exception stack below!

What is the problem with this runtime/post-application deployment of the service component?

Please note:
With Apache Felix and SCR, there is no problem with the runtime deployment at all.

Many thanks, Csaba.

Framework is launched.
