Deploy jruby project to tomcat in windows platform

Question

I am newbie in the ruby world, after doing some research I can generate a demo rails application and testing on the webrick server

But I have encounter the problem when I start to deploy with tomcat I use warbler to generate war file for deployment successfully without error Copy the war under the folder of webapps on Tomcat 7.0 start the server and try to run on the browser I found that assets file is not accessible & the controller method cannot redirect to correct view, but display "We're sorry, but something went wrong." message

Config of the deployment I have try

JRuby 1.7.0
Gems    
    jruby-rack 1.1.10, 1.0.10
    rails 3.2.9, 3.2.0
    warbler 1.3.6, 1.3.2
Tomcat 7.0.32

here is the access log from tomcat

It's seem that the routing problem is occur, is it the problem when I deploy the rails application other than the ROOT location?

I have research the similar topic of this, I have try some solution, such as adding the below command at production.rb, but no help.

config.action_controller.relative_url_root = "/demo"

Thanks for your solutions

Answer 1

Did you precompile your assets before warbling?

You need to run rake assets:precompile to generate static content before running warble
