[Rails] Re: Anyone successfully ran JRuby 1.5.3, Rails 3, Tomcat6

Ruby on Rails Tuesday, November 2, 2010

OK - it is somehow related with your tomcat setup.

my application works with tomcat6 as well with jetty.

I also found your previous post. which was related to mysql-connector-
java-5.1.13-bin.jar

my WEB-INF/lib directory from the warfile has only jruby-complete.jar
+ jruby-rack.jar in it, everything else comes from the gems in WEB-INF/
gems.

next thought is that the tomcat has mysql-connector-java-5.1.13-
bin.jar in shared lib for warfiles ?

with regards, Kristian
