Hello all,

I just bought Simply Rails 2, and I have a problem when starting the local webserver.
I'm on OSX Tiger, so WEBrick 1.3.1 is installed, but after typing 'ruby script/server' I see:
=> Booting WEBrick
=> Rails 2.3.5 application starting on hxxp://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server
[2009-12-08 21:53:24] INFO WEBrick 1.3.1
[2009-12-08 21:53:24] INFO ruby 1.8.6 (2007-03-13) [powerpc-darwin8.11.0]
[2009-12-08 21:53:24] WARN TCPServer Error: Address already in use - bind(2)
Exiting

what other app is using the same address, and how can I make webrick work ?

TIA

ps: I had to write 'hxxp' cause of an antispam "feature" of this forum
