It's actually all described in chapter 7.5 of "Java Generics and Collections" which the Posse have endorsed in the past. Basically you can introspect it (look for ParameterizedType) and it can help you in a few instances, but in my humble experiences those solutions often turns ugly and fragile (played with that a while ago: http://coffeecokeandcode.blogspot.com/2008/05/type-strategy-pattern.html).
