Re: Having Trouble Deploying JRuby on Rails app to Tomcat 6

I'm able to run my rails applications inside different context paths than root, with jruby-rack (which warbler uses) and jetty-rails. Curiously, it required no extra effort!

Would you mind testing your app in jetty-rails? Perhaps it fixes something without even realizing it.

Thanks for the tip.  I may try this next, but regardless of whether or not there's a way to get my rails app working without it running as the root app, I'd still like to deploy it as the root app.  Rails has some internal logic that assumes it is running as a root app, so I feel like I'll probably run into more things down the road that don't work right if it's not the root app.

Thanks,
Myron

Hi,

Whenever possible don't use relative paths in your rails app. Use instead
RAILS_ROOT + '/' + filename. If you can't avoid using relative paths, you
don't have to make you rails app a ROOT app; instead you can put the
contents of the folder public into the folder webapps of your tomcat. That
problem happened to me when using Jmaki and forced me to take the
"resources" folder that was in the my rails app's public folder and move it
to the "webapps" folder of tomcat (which is basicaly the root folder for
tomcat) without me having to make my app a root app.

I guess for you, you could just move the images folder to the webapps
folder.

Best regards,
Juan
