Hi all,

I stuck with the following design issue, any help or comments would appreciated!
We are about to build an enterprise application platform in a specific business domain, based on OSGi and Virgo.
In concept, every individual platform-applications are packaged as plans or pars, and consumes some common Platform services, its fine. On the other hand, the Platform would have a "Dasboard", reporting the application-states to operational personnel.
For this, my first design approach was that each Platform application should implement an interface and register the implementation in the service-registry:

public interface IApplicationInfo {
	public String getApplicationName();
	public String getApplicationVersion();
	public SystemState querySystemState();
	...
}

Then I realized, that "scoping" in Virgo is perfectly well-done, so outside from the applications the registered services could not be seen! Bundles in the platform can not got references to these IApplicationInfo services.

So how could I build up a platform with cooperating applications?
What is the recommended pattern for this application-platform case?

Thx,
Gabor
