Just checked - there is no cookie when I run my app in a java container
so no session is established!
Everything works when I run the application from mongrel/webbrick using
CRuby. Heck, it also works when running webbrick from jruby using jruby
script/server!
The only session related difference in the code is what I took from your
slides. I.e.
if defined?(JRUBY_VERSION) && defined?($servlet_context)
# Java session store:
config.action_controller.session_store =
:java_servlet_store
# Do nothing in impl. - let java handle this.
class CGI::Session::JavaServletStore
def initialize(session, options) end
def restore; end
def update; end
def close; end
end
end

As long as you don’t specify any session store (e.g.,
config.session_store is commented out), :java_servlet_store should be
used as the default. You can verify this by checking your browser
cookies. You should see JSESSIONID instead of the typical Rails/Ruby
cookie name.
