The error while I got while working with rails version 3.0.7 is
Please install the mysql2 adapter: `gem install activerecord-mysql2-adapter` (no such file to load — active_record/connection_adapters/mysql2_adapter)
Solution:-
In GemFile change
gem ‘mysql2’ to gem ‘mysql2’, ‘< 0.3’
and bundle it.

1) here the Gemfile means file found in the top directory( which will created while creating rails application) . it’s a text file and you want to edit content of the file.
2) In NetBeans IDE you will get the command in the right button click on project name
