I was able declare my forms variable and also establish a connection to my MySQL Database, but when I ran the program it give me error Class.forName not found. Meanwhile, I think the syntax is correct:
Class.forName("com.mysql.jdbc.Driver").newInstance();
So what is the possible solution and the possible cause of such an error?
This means that the mysql JDBC driver is not included in your classpath.
have you put the MySQL jar to the project classpath or to the web container lib folder?

I created a mysql database with Ruby. I want to use it on my Rails app. How can I do it? How can I read data with Rails without any database?
Not sure what the real question is, but by default Rails uses a SQLite DB for development and testing. This can be changed in the database.yml file found in the config directory.
However I would really start here Rails Guides

I've been searching information about how access, MySQL, SQL Server and Oracle save the metadata of the databases, and I couldn't found it.
You can retrive MetaData of the table "database independent" using JDBC:
DatabaseMetaData databaseMetaData = connection.getMetaData();
You just need to add the connector (can be MySQL JDBC, SQL Server, SQLite, Oracle, Postgree, etc).

I use Tomcat and Quercus.
Quercus want mysql_connect, How add mysql_connect argument?
mysql_connect() has been deprecated as of PHP 5.5.0 as per the below document
http://php.net/manual/en/function.mysql-connect.php
Make sure why you need mysql_connect to do it. The betterway to connect MySQL it is by using mysqli_connect.
Codeigniter provides the facility for mysqli by default. You just need to create a model as specified here

Actually my Connection string is :
Data Source=OSBORNECHARLES2;Initial Catalog=TWO;Integrated Security=True;User ID=sa;Password=123
May be this is because you have enabled "Integrated Security=True" set it to false. And try with a real sql server login.
