Just a quick note on doing JSON with Spring MVC, under WebSphere 8.5.5 Traditional.
This version of WebSphere includes Jackson 1.6.2 under the covers, for JSON serialization. (Apparently in WebSphere Liberty, the included Jackson isn't available for applications to directly use, but it is in WebSphere Traditional. On Liberty, you have to deploy your own copy of Jackson anyway.)
