Hi all, I'm trying to deploy a rails app using jruby, by bundling it as a war file and using a Java server (tried Tomcat and Jetty). The twist is that I want to compile everything in the /app/ and /lib/ directory to bytecode (".class") files, instead of using the rb files. You might ask why, and reasonably so: it's to comply with an awkward request from a client. I read through an old message on this very subject, which is archived here: http://ruby.11.n6.nabble.com/Compiling-Rails-app-t... My problem is this. After compiling the ruby files to .class files and removing, I test that the app actually works by starting up webrick (jruby -S rails server) - no problems there, the app works fine. I then bundle it up as a war file using warble, and drop it into the webapp directory on Jetty or Tomcat. I then get the same error on both of these servers: *Jetty* org.jruby.exceptions.RaiseException: (LoadError) load error: /var/cache/jetty/data/Jetty__8080_root.war___.an5myb/webapp/WEB-INF/app/models/user -- java.lang.NoSuchMethodError: org.jruby.javasupport.util.RuntimeHelpers.preLoad(Lorg/jruby/runtime/ThreadContext;Ljava/lang/String;Z)V at org.jruby.RubyKernel.require(org/jruby/RubyKernel.java:1027) at ActiveSupport::Dependencies::Loadable.require(/var/cache/jetty/data/Jetty__8080_root.war___.an5myb/webapp/WEB-INF/gems/bundler/gems/rails-4894465c3527/activesupport/lib/active_support/dependencies.rb:251) ... *snip* *Tomcat* org.jruby.exceptions.RaiseException: (LoadError) load error: /var/lib/tomcat7/webapps/ROOT/WEB-INF/app/models/user -- java.lang.NoSuchMethodError: org.jruby.javasupport.util.RuntimeHelpers.preLoad(Lorg/jruby/runtime/ThreadContext;Ljava/lang/String;Z)V at org.jruby.RubyKernel.require(org/jruby/RubyKernel.java:1027) at ActiveSupport::Dependencies::Loadable.require(/var/lib/tomcat7/webapps/ROOT/WEB-INF/gems/bundler/gems/rails-4894465c3527/activesupport/lib/active_support/dependencies.rb:251) ... *snip* I'm intrigued by the fact that it's a "NoSuchMethodError", but I have no idea how jruby works (I only started using it a couple of days ago, and still trying to get to grips with it). I should also mention that this only occurs when compiling the app directory to bytecode, i.e. packaging the ruby files as a war and running on Tomcat/Jetty works fine. Has anyone got any idea what my problem could be? Any help would be very appreciated. Thanks, Jon -- View this message in context: http://ruby.11.n6.nabble.com/Problems-deploying-co...
