Swordfish: Eclipse's OSGi-based SOA framework
It's a well known fact among those working on SOA projects there is no such thing as "SOA in a box" or a silver bullet for achieving an SOA, so much as it is a combination of software infrastructure, design philosophy, tools and, of course, buy in from the top brass at any organization. It's, in essence, a series of pieces, each of which gets a project closer to its full statement of intent and purpose for building a SOA.
