jrubyonrails - JRuby on Rails app on and JBoss 4.2.0/Tomcat 5.5 -

my jruby on rails app works fine on tomcat 6.0, when deploy on company's webfarm jboss 4.2.0/tomcat 5.5 (servlet api 2.4) fails following stack trace:

thanks, arkadiy

first note jruby-rack changed servlet 2.5 of 0.9.7 release. in order run on 5.5 you'll have downgrade 0.9.6 or earlier. may bit tricky warbler dependencies can manually adjust jars in warbler config file using config.java_libs.

as errors above, haven't seen them before. thing comes mind native/ffi support doesn't work in containers , may need disable -djruby.native.enabled=false.
