Known Problems / Troubleshooting

I installed jruby via rvm and culerity doesn’t work

• try this: http://gist.github.com/268216
• this might be newer: http://rvm.beginrescueend.com/integration/culerity/

bundler

if you get an error message from the jruby process that some gems could not be found, try setting this in your env.rb

Culerity.jruby_invocation = 'RUBYOPT="" ' + File.expand_path("~/.rvm/bin/celerity_jruby")

trying to activate an “onmouseover” event using the #fire_event instance I get a “NoMethodErrror”

you are probably using the (old) rubyforge version of celerity. try the github version instead. (thanks to @jamescallmebrent)

The Java process isn’t shut down which results in processes piling up (Ubuntu)

this has been reported by @josevalim and i haven’t been able to reproduce this. here’s his solution: add an exit(0) call to the on_exit block in common_celerity.rb

 at_exit do
    $browser.exit
    $server.close
    exit(0)
  end

I’ve also had this happen to me under 10.5.7 — @Caius

I want culerity to run faster!

jRuby v1.5 (and, I think, v1.4) has an option called nailgun that spawns a JVM that all other instances of jruby then connect to. This saves the boot time for a JVM each time you run a jruby command. This can make culerity run significantly faster. To setup:

• Run jruby --ng-server in a separate shell
• Make sure the jruby call that culerity uses passes the --ng flag. Perhaps the easiest way to do this is to set ENV["JRUBY_OPTS"]="--ng"
• You’re done! First time through you won’t notice any difference, but subsequent runs should be much faster.
• NOTE: Passing the --ng option without first setting up the nailgun server will cause this error:

   connect: Connection refused 

sometimes there are old emails in the ActiveMailer queue

• If you have problems with old mails appearing in the mail queue then you can find a proposed fix here: https://github.com/langalex/culerity/issues#issue/1 . As of culerity 0.2.12 / 16. Nov. 2010 that problem is not yet fixed in the git repository.

cucumber fails with `require’: no such file to load — culerity/celerity_server (LoadError)

• See this thread
  One solution is to use RVM, the other to install culerity in jruby’s path: jruby -S gem install culerity

related tools

• modified timecop by @liangzan: freeze time even across processes, i.e. you can call timecop to change the time in the rails webserver process

Configuration

sending emails

• if you need to test sending of mails, then you need to set config.action_mailer.delivery_method = :persistent inside your environments/culerity.rb. You can find the rationale here: http://groups.google.com/group/culerity-dev/browse_thread/thread/6326c447c5d8706c .
