For now, I'll probably stick with plain old Java. You should consider Clojure. The community is evolving in a way that compensates for some of the tool chain problems, and Leinengen is definitely more intuitive than SBT. My traditional bias favors static typing, but I think Clojure might beat Scala because for most web applications, runtime typing (you can implement similar guarantees as in compiled languages; however, checking isn't at compile-time and therefore your testing will be less performant) is good enough.
