After upgrading from Rails 2.0.2 to 2.3.5 my WEBrick server in NetBeans started printing the following message on its log and the application would not connect to the database.
The bundled mysql.rb driver has been removed from Rails 2.2. Please install the mysql gem and try again: gem install mysql.
I installed the refered gem but would still have the same problem when starting WEBrick, even after restart of the IDE.
