Answer 1

To start, per the documentation at http://static.springsource.org/spring-social/docs/1.0.x/reference/html/overview.html#overview-dependencies, Spring Social is only supported on Spring 3.0.5 or higher. (And when Spring Social 1.1.0 is released, it will only be supported on Spring 3.1 or higher.)

My first recommendation is to try it on at least Spring 3.0.5 (and ideally on 3.0.7 or even 3.1.2 if that’s an option for you). If that doesn’t fix your problem, then I can look into it a bit deeper.
