Hi all,  
I successfully deployed my JRuby on Rails app on Tomcat  
In a jsp page I’d use ${pageContext.request.contextPath} to obtain my  
context path.How could I do this in a Ruby controller?

Thanks  
Rafael R.

What does the context path represent within JSP?

JRuby-Rack exposes a controller method called #servlet\_request. So you  
could try `servlet_request.context_path` inside a controller or view.
