For Java I would say that Dropwizard if not a direct copy, definitely was inspired by the simplicity of Rails. For Python it would probably be Django, but I'm still a novice in Python. In terms of build chain, the declaritive nature of Maven as a build tool (far from perfect, but extensible) and then likewise in Python the setup.py bits. Looking at other languages, Cargo has a similar declarative build chain for Rust, and I think a lot of the package management that we see out there was inspired generally by Ruby. Again, cool concepts, but for me Ruby never was more than a toy.
