config.action_view.debug_rjs will be removed in 3.1, from 3.1 onwards you will need to install prototype-rails to continue to use RJS templates

I am getting a warning.

DEPRECATION WARNING: config.action_view.debug_rjs will be removed in 3.1, from 3.1 onwards you will need to install prototype-rails to continue to use RJS templates . (called from <top (required)> at /Users/me/projects/my_app/config/environment.rb:5)

Can anybody tel me how to solve this. I am not using prototype I am using standard jquery js file with jquery.rails.js instead of gem.

The warning is being caused by your config file. Look for a line like config.action_view.debug_rjs = true in {app_root}/config/environments/development.rb or production.rb and comment it out. If you're not using rjs views anyway then you won't miss the debugging in development mode anyway (and it's off by default in production)
