irb problems

[dostanko]

Hi, guys!

At last, I've managed to run helloworld jROR+googleappengine.
I use rails 2.3.4, jruby 1.3.1, MAC OS X 10_5_8, java 1.5.0_19. I used
http://rails-primer.appspot.com/ instructions. First I had problems
with dev_appserver(but remotely on your server it worked). On every
second non-static request it faild with next exception:

com.google.appengine.tools.development.ApiProxyLocalImpl log
SEVERE: [1253517440528000] javax.servlet.ServletContext log:

I just commented 31-th line in file WEB-INF/lib/gems.jar!/gems/
actionpack-2.3.4/lib/action_controller/reloader.rb (in red).

def self.run(lock = @@default_lock)
#lock.lock
begin
Dispatcher.reload_application
status, headers, body = yield
[status, headers, BodyWrapper.new(body, lock)]
rescue Exception
lock.unlock
raise
end
end

Seems works fin locally now and I can work with datastore through web
interface,
but I steel can't run irb. Command "appcfg.rb run -S irb" just waiting
for something for ever with no messages. Have you any ideas what's go
wrong with my environment?

Thanks fro supporting ruby,
Best regards!
