Ruby on Rails setup problem

Seifer

I'm following a tutorial from IBM; have downloaded RoR and the gems I need.
I've created a new project and then I run the command "ruby script/server". This appears to run fine. However, when I enter "http://localhost:3000/" into my browser it can't find the page.
I've tried googling around but no one else seems to have gotten this problem. I tried one solution attempt of reseting winsock but it didn't do anything. When I ran the server first I told the firewall to unblock it and I've tried running it with the firewall off.
It's probably something extremely obvious but I'm at a loss. Any ideas?

Got an answer else where.
"http://127.0.0.1:3000" works in case anyone is curious.

localhost should have worked too. Strange that.

So I've left the IBM tutorial I was trying alone for the moment. The sample solution it provides seems to run fine but when I follow the instructions to create it myself it doesn't work.
So I'm trying the hello world type exercise here. When I get to step 3.4 "rake db:create" I get a pop-up saying "This application has failed to start because sqlite3.dll was not found. Re-installing the application may fix this problem".
So sqlite3 is definitely installed. And I removed and reinstalled and no change.

The IBM sample code seems to use sqlite and runs fine but I get the same error when following the steps it outlines to recreate it.

I'm working in Windows Vista.

Any ideas?

You will need to download the sqlite3 dll and place it in your path so windows can find it.

Thank you very much for that. What was throwing me was that the IBM sample code was working without the dll. Once I downloaded it both projects I created worked

did you rake db:migrate
ruby script/server

I use Instant rails for all my stuff
try 0.0.0.0:3000

All my problems have been solved for the moment

But from my limited understanding, I don't think it would be possible to migrate a db before creating it.
And no 0.0.0.0 doesn't work for me, only 127.0.0.1

strange that,
but then again i use scaffolding to create my fields

So I've gone back to the IBM tutorial linked to in my previous post.
Just running the sample code they provide. When I click on the "generate using rexml" link I get what's in the attached image.
So assuming they provide a working solution, any ideas on what I'm missing to make this work?
As far as I know rexml comes preloaded with ruby and I can't see it in the gem list.

Here's the offending method:
(line 70 highlighted with ***, they're not in the code)

  def generate_rexml
    doc = REXML::Document.new
    root = doc.add_element( "Food" )
    DISHES.each{ |element_data|
      
      dish_element = root.add_element( "Dish" )
      
      ***dish_element.add_attribute( "rating", element_data[:rating] )***
      dish_element.add_attribute( "category", element_data[:category] )
      
      dish_name_element = dish_element.add_element( "DishName" )
      dish_name_element.add_text( element_data[:dish_name] )

      where_to_buy_element = dish_element.add_element( "WhereToBuy" )      
      where_to_buy_element.add_text( element_data[:where_to_buy] )
    }
    doc.write( out_string = "", 2 )
    return out_string
  end

Always helps to step away from these things for awhile.
While I haven't fixed it, I have narrowed it down by trying the other link which uses Builder to generate the xml instead of rexml and it works fine. So the problem is definitely to do with rexml.
Whether it's not installed correctly or the code is using some deprecated method calls, I don't know.

That tutorial is over 2 years old. I was doing an old tutorial for ror and ran into lots of problems. Changed to a different one and was smooth sailing from there.

Fair enough.
I'm gonna see how far I can get just using the Builder side of it for now anyway.
