The Spring framework is the most ubiquitous Java framework today and the easiest way to solve many problems. At some point, however, developers start to feel Java applications just can't be any simpler because Java itself is not very simple. It is at this juncture that most people look for alternatives. For those, there is Spring Roo, the highly productive development framework for Spring users.
Akka is using the Actors together with STM to create a unified runtime and programming model for scaling both UP (multi-core) and OUT (grid/cloud). Akka provides location transparency by abstracting away both these tangents of scalability by turning them into an ops task. This gives the Akka runtime freedom to do adaptive automatic load-balancing, cluster rebalancing, replication & partitioning
