Having Trouble Deploying JRuby on Rails app to Tomcat 6
by Myron Marston

Rate this Message:
I'm developing a JRuby on Rails app using netbeans 6.1. I'm trying to deploy to Tomcat 6. I've installed warbler as a plugin, and it's generated my WAR file. I copied it to $TOMCAT_HOME/webapps and I can access it in my browser at http://localhost:8084/$YOUR_APP_NAME just fine. However, none of my images show on the page, and after doing some research on Google, it's clear that my app needs to run as the root webapp in Tomcat because of some of the logic used by the rails asset tags.
This is my first time using Tomcat, so I'm not quite sure how to configure Tomcat to make my app run as the root. Googling the topic gave me several things to try (e.g. renaming my war as ROOT.war and removing the existing ROOT webapp; creating a ROOT.xml file in $CATALINA_HOME/conf/[enginename]/[hostname]/ with a docBase element pointing to my war file), but none of these are working. In each case, I get a java.lang.OutOfMemoryError. Here's the stack trace: Jun 10, 2008 2:25:30 PM org.apache.catalina.core.ApplicationContext log SEVERE: Exception caught org.jruby.rack.RackInitializationException: IO error -- builtin/java/exceptions from file:/C:/Users/Myron/.netbeans/6.1/apache-tomcat-6.0.16_base/webapps/ROOT/WEB-INF/lib/jruby-complete-1.1.2.jar!/META-INF/jruby.home/lib/ruby/site_ruby/1.8/builtin/javasupport.rb:47:in `file:/C:/Users/Myron/.netbeans/6.1/apache-tomcat-6.0.16_base/webapps/ROOT/WEB-INF/lib/jruby-complete-1.1.2.jar!/META-INF/jruby.home/lib/ruby/site_ruby/1.8/builtin/javasupport.rb' from file:/C:/Users/Myron/.netbeans/6.1/apache-tomcat-6.0.16_base/webapps/ROOT/WEB-INF/lib/jruby-complete-1.1.2.jar!/META-INF/jruby.home/lib/ruby/site_ruby/1.8/builtin/javasupport.rb:1 at org.jruby.rack.DefaultRackApplicationFactory.newRuntime(DefaultRackApplicationFactory.java:85) at org.jruby.rack.DefaultRackApplicationFactory.createApplication(DefaultRackApplicationFactory.java:144) at org.jruby.rack.DefaultRackApplicationFactory.newApplication(DefaultRackApplicationFactory.java:44) at org.jruby.rack.DefaultRackApplicationFactory.getApplication(DefaultRackApplicationFactory.java:52) at org.jruby.rack.PoolingRackApplicationFactory.getApplication(PoolingRackApplicationFactory.java:92) at org.jruby.rack.DefaultRackDispatcher.process(DefaultRackDispatcher.java:31) at org.jruby.rack.RackFilter.doFilter(RackFilter.java:51) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:235) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.netbeans.modules.web.monitor.server.MonitorFilter.doFilter(MonitorFilter.java:196) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:235) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:233) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:175) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:128) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:286) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:844) at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:583) at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:447) at java.lang.Thread.run(Thread.java:619) Caused by: org.jruby.exceptions.RaiseException: IO error -- builtin/java/exceptions Caused by: java.lang.OutOfMemoryError: Java heap space Not sure if this helps, but here's my environment: Windows Vista MySQL 5 Netbeans 6.1 Rails 2.1 JRuby 1.1.2 Tomcat 6.0.16 Anyone know how to get this to work?

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.

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.

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 suggestion! I assume jetty-rails requires Jetty? I'd prefer not to use a different java server. I'm going to be using a hosting company for my web app, and virtually all the hosting companies that support java support Tomcat. I haven't seen many that support Jetty.

You are right. It comes with a bundled jetty.
I was asking you to test, just to see if jetty-rails is doing something to support context paths other than root. In that case, I could tell to you what it is being done and you might reproduce it in your jruby-rack + tomcat deployment.
