Haven't looked at it in a little while now, but from what I recall, here are some thoughts on issues we encountered: - there was a problem exposing multiple beans as services from one Spring context. - cannot use AOP across multiple implementation.spring components (each component has a different Spring context) - in general unable to share beans across multiple components (probably as designed) - some interoperability between sca properties and beans (using one to inject into the other) - maybe policy could tie into/leverage AOP and Spring transaction management? - to solve some of the above, perhaps a parent Spring context could be defined at the composite level?

My scenario is that the old application based on Spring and the new application based on sca and the new will reuse the Spring bean. So the fundamental function is the assembly between Spring bean and sca component and deploying the Spring bean as a sca service. > > >What use cases do you have beyond the SCA/Spring spec 1.0? > >What are the main issues or wish-to-have features in our current >SCA/Spring integration ? > Some functions of sca and Spring is intersect such as transaction security etc, so the coordination will be important. > >-- >Luciano Resende >Apache Tuscany Committer >http://people.apache.org/~lresende >http://lresende.blogspot.com/
