Expanding our horizons with new and interesting technology.

I have worked with Guidewire for a long time now, and one of the things that has never been up for consideration was architecture. Guidewire Products dictated this. XCenters are based on Java, J2EE, and several proprietary frameworks, such as workflow, messaging, rules, UI configuration, etc. We always use OOTB as much as possible, so architecture decisions are few and far between. That doesn't mean you don't have to use the frameworks correctly. It just means you don't get to choose the frameworks (if that makes sense).
