SQLite3::SQLException: unable to open database file

Hi.
I was trying to code same as the rails guide : getting started.
I could follow steps to 6.3 Working with Posts in the Browser.
(setting home page, creating a resource, running a migration)

After clicked create button, errors are occured.
SQLite3::SQLException: unable to open database file: INSERT INTO
"posts" ("name", "created_at", "title", "updated_at", "content") VALUES
('123123123', '2009-04-25 22:23:51', '12312312', '2009-04-25
22:23:51', '4123123123')

There is a db file at db folder named development.sqlite3
what's wrong with me?
Somebody help me, please.

Thanks in advance.

Also, looking over the directions in the guide, this part is plain
wrong:

Of course ruby, ruby gems and sqlite3 are installed on my system
(CentOS 5.3)

#gem install sqlite3-ruby
Building native extensions. This could take a while...
Successfully installed sqlite3-ruby-1.2.4
1 gem installed
Installing ri documentation for sqlite3-ruby-1.2.4...
Installing RDoc documentation for sqlite3-ruby-1.2.4..

it is installed properly, isn't it?
I can execute irb shell(ruby), sqlite3.

Did your migration complete successfully? i.e. does the table posts
exist in your database?
Does your database.yml file point to your db file -
development.sqlite3? It should look something like this:
development:
  adapter: sqlite3
  database: db/development.sqlite3
  pool: 5
  timeout: 5000
