Just moved my homegrown GTD-app from one server to another. I’m not completely familiar with the gem system yet but I noticed that “gem install rails -y” for instance didn’t pull in the mongrel gem. I had to add quite a few gems manually before I had anything working at all. Now I’m able to use the app starting it with “./script/server webrick” and it works. When I start it with “./script/server” it comes up but any requests generate the following error: =\> Booting Mongrel (use ‘script/server webrick’ to force WEBrick) =\> Rails application starting on [http://0.0.0.0:3030](http://0.0.0.0:3030) =\> Call with -d to detach =\> Ctrl-C to shutdown server Running Mongrel server in production mode at 0.0.0.0:3030 Server ready. calling Dispatcher.dispatch uninitialized constant RailsHandler::Dispatcher /usr/lib/ruby/gems/1.8/gems/activesupport-1.4.0/lib/active\_support/ dependencies.rb:478:in `const_missing' /usr/lib/ruby/gems/1.8/gems/mongrel-0.3.3/bin/mongrel_rails:75:in `process’ /usr/lib/ruby/gems/1.8/gems/mongrel-0.3.3/bin/mongrel\_rails:73:in `synchronize' /usr/lib/ruby/gems/1.8/gems/mongrel-0.3.3/bin/mongrel_rails:73:in `process’ /usr/lib/ruby/gems/1.8/gems/mongrel-0.3.3/lib/mongrel.rb:371:in `process_client' /usr/lib/ruby/gems/1.8/gems/mongrel-0.3.3/lib/mongrel.rb:332:in `initialize’ /usr/lib/ruby/gems/1.8/gems/mongrel-0.3.3/lib/mongrel.rb:331:in `timeout' /usr/lib/ruby/gems/1.8/gems/mongrel-0.3.3/lib/mongrel.rb:331:in `initialize’ /usr/lib/ruby/gems/1.8/gems/mongrel-0.3.3/lib/mongrel.rb:328:in `initialize' /usr/lib/ruby/gems/1.8/gems/mongrel-0.3.3/lib/mongrel.rb:328:in `new’ /usr/lib/ruby/gems/1.8/gems/mongrel-0.3.3/lib/mongrel.rb:328:in `initialize' /usr/lib/ruby/gems/1.8/gems/mongrel-0.3.3/lib/mongrel.rb:328:in `times’ /usr/lib/ruby/gems/1.8/gems/mongrel-0.3.3/lib/mongrel.rb:328:in `initialize' /usr/lib/ruby/gems/1.8/gems/mongrel-0.3.3/bin/mongrel_rails:166:in `new’ /usr/lib/ruby/gems/1.8/gems/mongrel-0.3.3/bin/mongrel\_rails:166:in `start_mongrel' /usr/lib/ruby/gems/1.8/gems/mongrel-0.3.3/bin/mongrel_rails:181:in `run’ /usr/lib/ruby/gems/1.8/gems/mongrel-0.3.3/lib/mongrel/command.rb: 183:in `run' /usr/lib/ruby/gems/1.8/gems/mongrel-0.3.3/bin/mongrel_rails:224 /usr/lib/ruby/gems/1.8/gems/activesupport-1.4.0/lib/active_support/ dependencies.rb:489:in `load’ /usr/lib/ruby/gems/1.8/gems/activesupport-1.4.0/lib/active\_support/ dependencies.rb:489:in `load' /usr/lib/ruby/gems/1.8/gems/activesupport-1.4.0/lib/active_support/ dependencies.rb:489:in `new\_constants\_in’ /usr/lib/ruby/gems/1.8/gems/activesupport-1.4.0/lib/active\_support/ dependencies.rb:489:in `load' /usr/lib/ruby/gems/1.8/gems/rails-1.2.1/lib/commands/servers/ mongrel.rb:60 /usr/local/lib/site_ruby/1.8/rubygems/custom_require.rb:27:in `gem\_original\_require’ /usr/local/lib/site\_ruby/1.8/rubygems/custom\_require.rb:27:in `require' /usr/lib/ruby/gems/1.8/gems/activesupport-1.4.0/lib/active_support/ dependencies.rb:496:in `require’ /usr/lib/ruby/gems/1.8/gems/activesupport-1.4.0/lib/active\_support/ dependencies.rb:496:in `new_constants_in' /usr/lib/ruby/gems/1.8/gems/activesupport-1.4.0/lib/active_support/ dependencies.rb:496:in `require’ /usr/lib/ruby/gems/1.8/gems/rails-1.2.1/lib/commands/server.rb:39 /usr/local/lib/site\_ruby/1.8/rubygems/custom\_require.rb:27:in `gem_original_require' /usr/local/lib/site_ruby/1.8/rubygems/custom_require.rb:27:in `require’ ./script/server:3 Could it be that I’m missing another gem?

Please check whether you stop your first WEBrick server. This error also come when 1 application is running on the particular port and again if you want to run another application the same port.
