I am using Fedora 9 as Os and mysql as database.

I read all the error than i got to know. I need to change my database.yml file.

in that file i have following text;

adapter: jdbcmysql

i changed that to:

adapter: jdbcmysql

socket: /var/lib/mysql/mysql.sock

I thoutht jruby database issue but not. the database setting is an issue.
