Question

I am a newbie in jruby on rails. I have created a basic application using rails and generated the war file and deployed in tomcat container. when i start the application i get the below error. I am using using oracle and have uncommented the following entry under the config/warble.rb file:

config.gems += ["activerecord-oracle_enhanced-adapter", "jruby-openssl"]

Resolved. Add the ojdbc6.jar as dependencies under the lib directory of WEB-INF under the webapps directory in tomcat.
