Tomcat 5.5 & Warble

Ruby JRuby
1

Hi

I’m just stated to try to get a Tomcat to run a Jruby rails app, but i
run into a strange problem that it seems some other people have had as
well. After i put the WAR file in webapp folder and try to run access it
i get the following error.

SEVERE: Warning: error application could not be initialized
org.jruby.rack.RackInitializationException: IO error – rack
from
file:/var/lib/tomcat5.5/webapps/helloworld/WEB-INF/lib/jruby-rack-0.
9.1.jar!/jruby/rack.rb:7
from
file:/var/lib/tomcat5.5/webapps/helloworld/WEB-INF/lib/jruby-rack-0.

from :1

I’ve tried to figure out what can be wrong through google and
Tomcat/Jruby tutorials but haven’t been able to find any solution

Any suggestions to how to solve this problem would be very appriciated.
(im running on debian lenny with Jruby 1.1.3)

Thanks

Does your log file contain an extended stack trace that looks like this?

I haven’t uncovered the reason for the error yet, but appreciate your
help in troubleshooting it.

Hi Nick,

Yes it does, however i tried to deploy the same war on a Glassfish
instance on the same server and it worked fine so i guess it’s primarly
Tomcat related.

I guess so. Albert confirmed the same, so I’ll have to do some testing
with Tomcat 5.5 and see if I can figure it out.

Cheers,
