Building Spring-Seam Hybrid Components For Web Applications

Spring and JBoss Seam frameworks provide different set of features for developing enterprise web applications. Is it possible to use these two frameworks together in web applications? This topic was the main focus of a recent article and a java community forum discussion on how the strengths of each of these frameworks can be used together.

I posted a news item on this topic on InfoQ. I am big fan of Spring and I have been using it for past 3 years. But I haven't used Seam framework yet. Any one using these frameworks together in their applications? If so, how did find integration? Are Spring and Seam complementary to each other?
