Rails - Feb 2012 - Problem in developing first application in Ruby application

Hi,
   I am a new guy in Ruby on Rails. Today I am trying to develop a
simple web application by making use of JetBrains RubyMine 3.1.1 IDE.
   My system configuration regarding Ruby on Rails is :
     OS- Windows, Ruby- 1.9.2p180 , Rails- 3.2.1, gem-1.8.15
   My folder structure is like :
      C:/ruby/rubygem/ApplicationFolderName(named as "Scripting")
   I run "gem install mysql" and "gem install mysql2" from
command
prompt under C:/ruby/rubygem/ , though I did not get the difference
between mysql and mysql2. Both the cases I got "1 gem installed", for
mysql2("Successfully installed mysql2-0.3.11-x86-mingw32") and for
mysql("Successfully installed mysql-2.8.1-x86-mingw32"). Also in
Editor,
showing to install mysql Drivers which are required for RubyMine to
connect to the Database(MYSQL Connector/J(5.1.18)). I install that
driver also.

   Now, I create a project having the type "Rails Application" and
database is "Mysql". I switch to the "Rails" view. Then try
to run this
application and get the following error:

    C:\ruby\bin\ruby.exe -e
$stdout.sync=true;$stderr.sync=true;load($0=ARGV.shift)
