Hello, I am trying to change my rails 1.2.6 application to rails 2.2 I have made all the other changes and able to make everything work except upload progress. When I try to start the mongrel server using the command mongrel_rails start -S config/mongrel.conf it throws the error ** Rails loaded. ** Loading any Rails specific GemPlugins ** Loading config/mongrel.conf external config script /usr/lib/ruby/gems/1.8/gems/gem_plugin-0.2.3/lib/gem_plugin.rb:163:in `create'': Plugin category /handlers does not exist (RuntimeError) from /usr/lib/ruby/gems/1.8/gems/mongrel-1.1.5/bin/../lib/mongrel/configurator.rb:263:in `plugin'' from /usr/lib/ruby/gems/1.8/gems/mongrel-1.1.5/bin/../lib/mongrel/configurator.rb:348:in `run_config'' from /usr/lib/ruby/gems/1.8/gems/mongrel-1.1.5/bin/../lib/mongrel/configurator.rb:347:in `open_uri_original_open'' from /usr/lib/ruby/1.8/open-uri.rb:32:in `open'' from /usr/lib/ruby/gems/1.8/gems/mongrel-1.1.5/bin/../lib/mongrel/configurator.rb:347:in `run_config'' from /usr/lib/ruby/gems/1.8/gems/mongrel-1.1.5/bin/mongrel_rails:121:in `cloaker_'' from /usr/lib/ruby/gems/1.8/gems/mongrel-1.1.5/bin/../lib/mongrel/configurator.rb:149:in `call'' from /usr/lib/ruby/gems/1.8/gems/mongrel-1.1.5/bin/../lib/mongrel/configurator.rb:149:in `listener'' from /usr/lib/ruby/gems/1.8/gems/mongrel-1.1.5/bin/mongrel_rails:99:in `cloaker_'' from /usr/lib/ruby/gems/1.8/gems/mongrel-1.1.5/bin/../lib/mongrel/configurator.rb:50:in `call'' from /usr/lib/ruby/gems/1.8/gems/mongrel-1.1.5/bin/../lib/mongrel/configurator.rb:50:in `initialize'' from /usr/lib/ruby/gems/1.8/gems/mongrel-1.1.5/bin/mongrel_rails:84:in `new'' from /usr/lib/ruby/gems/1.8/gems/mongrel-1.1.5/bin/mongrel_rails:84:in `run'' from /usr/lib/ruby/gems/1.8/gems/mongrel-1.1.5/bin/../lib/mongrel/command.rb:212:in `run'' from /usr/lib/ruby/gems/1.8/gems/mongrel-1.1.5/bin/mongrel_rails:281 the config/mongrel.conf contains uri "/", :handler => plugin("/handlers/upload", :path_info => ''/upload/create'', :memcached => UPLOAD_PROGRESS_CACHE), :in_front => true We are using memcache to store the upload progress info. This works smoothly in Rails 1.2.6. What has changed in the new rails version which is causing this error, how to get it working? Any help on this issue will be much appreciated. Thanks in advance.
