Status: 500 Internal Server Error when starting ruby applica


#1

I am trying to run an Ruby on Rails application developed internally.
Any input would be greatly appreciated…

When I start the server I get the following warning:

[shajizaidi@worf script]$ ./server
=> Booting WEBrick
=> Rails 2.3.2 application starting on http://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server

[2009-05-28 18:29:46] INFO WEBrick::HTTPServer#start: pid=4587
port=3000

I have checked that there is no other application using port 3000

With lsof | grep 3000

I have tried to start the WEBrick on a different port and get the same
warning:

[shajizaidi@worf script]$ ./server -p 3001
=> Booting WEBrick

When I try to access the application through the firefox browser I get
the following error and trace:
