WEBrick - What am I doing wrong?

I can start the WEBrick web server fine. But, when I try to access
http://0.0.0.0:3000, I get the follow:

[WEBrick]
$ script/server
=> Booting WEBrick...

I am surprised to see anything in the webrick log. I would not expect
0.0.0.0:3000 to route at all. What happens if you try to point your
web browser to http://localhost:3000 or http://127.0.0.1:3000? Same
error?

Yes.

  I've installed MySQL and MySQL Gem on my dev's box yesterday. But I don't
believe that the problem is it.

  Sorry my poor english.

Do you get friendlier messages when you use mongrel instead of webrick?

#<NoMethodError:
You have a nil object when you didn't expect it!
You might have expected an instance of Array.
The error occurred while evaluating nil.each>

You have a bad loop somewhere. Usually something like this is happening:
@product = Product.find(:all)
@product.each do |product|
  puts product
end

If you have no Products in the database you will get the error listed above.

usr/lib/ruby/gems/1.8/gems/rails-1.2.3.7116/lib/commands/servers/webrick.rb:53:
undefined local variable or method `start_debugger' for main:Object
(NameError)

The breakpointer is dead now. Use ruby-debug gem if you need to debug rails.

As I am a Gentoo user, I must compile everything on my box. So, I must
compile Ruby, Gems, Rails and everything else. My problem is that I forget to
add suport to fcgi + mysql when compiling.

  Sorry my mistake and thank you all for the time spend.

  All (server side) is working now. There are some bugs in my application. I
think that I can solve it by now. Thank you.
