问题
My rails project is deployed to tomcat with the help of warbler, but I need to be able to run rake tasks on that server.

Stay tuned. I hope to have this capability in Warbler 1.4. Jake Goulding, a community member, has been doing some great work on this.
Until then, a typical approach would be to ensure all your Rake and database scripts are present in the war file, then just unpack it somewhere, cd to WEB-INF inside the unpacked war, and run something like java -cp lib/jruby-core*.jar:lib/jruby-stdlib*.jar org.jruby.Main -S rake -T.
