paper "Grid Web Services and Application Factories"
This paper proposes a factory service to build distributed applications. A distributed application consists of many XCAT components. A running instance of an XCAT component is a web service with uses-port and provides-port. This paper defines an XML language to describe the connections between components. Compared with WSFL/BPEL, this CCA based approach gets rid of the central flow engine. So, there is no need of extra effort to describe information exchange between components.
This approach can be used complementarily with BPEL. The description of connections between components can work as an annotation to service partners in BPEL. Doing so will get benefit from both of them.

Could you please say some more about combining the CCA/XCAT approach with the BPEL approach, since this is not in the paper you have referenced.
I agree that the paper identifies a possible weakness with BPEL, which I hope may be addressed in future. See my blog at http://www.veryard.com/so/2004/09/bpel.htm
