Table 1: SCA and BPEL software packages
The only feasible open source packages available today (March 2010) are Apache Tuscany + ODE, to implement an architecture that uses SCA and BPEL technologies.
The book "Understanding SCA" is a very good guide to start with SCA, but it shows just a chapter of how to use SCA with BPEL in a small example.
There is a coming book of "Tuscany in Action" that will show how to use SCA and BPEL too, but let's see if they show something more than a simple example.
