Hello Jun:
J2-Cornerstone is very interesting. Two questions:
1) Have you thought of making HiveMind an implementation variant of j2-cornerstone with HiveMind service extend Cornerstone BaseService. Then make portlet as a HiveMind service.
Yes, Cornerstone is can implement other service frameworks and give them complete configurability (in 4 dimensions: components, relationships, control flows and preservation of customization across upgrades). Yes, HiveMind services can be implemented either as Cornerstone services (by extending BaseService) or as completely different services (by implementing e.g. a HiveMindServiceManager that creates HiveMind services). And better yet, Cornerstone services and HiveMind servivces can coexist without interfering each other. This shows how general Cornerstone is (with a high abstraction level). I don't know if the reverse (implementing Cornerstone with HiveMind) can be done or not.
2) Have you thought of making Commons-Chain as a cornerstone ServiceController.
Sure. That would be a great example of how Cornerstone allows you to implement your own service controllers, however different it may be.
Any thought on the combining J2-Cornerstone + HiveMind + Commons-Chain?
We can certainly look into it. However, I think different frameworks are designed for different purposes and thus each has its own reason of existence.
