Hi,
i have a question regarding running one of the riena snippets. I have just installed the targetplatform for riena in Eclipse Kepler. I have successfully tried out the example.client app.

Now I am trying to start one of the riena snippets.
This is what I have done so far:

1. Created a plugin project
2. Added org.eclipse.riena.client as a dependency
3. Start the HelloWorld Snippet using Run > Run As > Java Application

Running the program ends in a NP exception (see below) because the Eclipse RegistryFactory is not initialized. In case of an Eclipse Application this Registry would be initialized by the org.eclipse.core.internal.registry.osgi.Activator. How is this supposed to work if run as Java Application. Am I doing something wrong here?

Thx
Thorsten
