Casestudy: Composite Application Development at Safeco
The development team at Safeco got together to write a case study about their experiences applying SOA and how they used enabling technologies SCA, BPEL, and composite application approaches to reuse legacy code, enable runtime modifiability thanks to decoupling, Java and .NET interoperability, and the ability to deliver a complex solution integrating over 5 systems in less than 8 weeks with a small team.

Java != SCA and JBI was before WCF
SCA was developed by BEA and IBM and only recently handed over to an open standards body (OASIS). There is only one open implementation available which is still in its infancy.
Microsoft was rather late, introducing WCF with .NET 3.0 and there is still much uncertainty and doubt around this framework.
Each of these specifications has its merits and drawbacks, but in your case, JBI would have been worth a look, as your infrastructure is missing exactly those things that JBI already provides by default ("Future Directions"). Maybe you should have also invited a consultant from Sun (I don't work for them, just like open and proven standards).
Re: Java != SCA and JBI was before WCF
JBI is merely a belated attempt to standardize integration infrastructure of integration platform of the 90s (java.sun.com/integration/pa1/docs/introduction/...). It is based on a very old "hub & spoke" pattern and requires that the NMR be at the center of the university. It does not even support composition between JBI infrastructures !! So if by any chance two JBI infrastructure made it to your organization, you are on your own to make sure that a binding component in one can talk to a binding component in another or leverage a service engine from one into the other.
It is misleading to associate JBI with SOA. Can I use a JBI infrastructure to expose services? Yes, just like a gazillion technologies that act as a service container. Should I construct my SOA infrastructure on JBI? Hell no.
