Stop using NetBeans to generate your rails application. Use the command prompt to do it then import your newly created app into NetBeans for editing. Follow this guide for learning how to create rails apps: http://guides.rubyonrails.org/getting_started.html

*when i do that using command prompt* *rails server* *a folder is created "server" into my project directory..* *

That sounds like you've got rails 2.x. With rails 2 you run ruby script/server to start the server (rails server is for rails 3 and above)

The use of the rails command line tools change substantially between 2.x and 3.x

Can't help you with your netbeans troubles - I've never used it before.

Please stop posting the same message multiple times...

when i do that using command prompt rails server a folder is created "server" into my project directory..

So you have Rails 2.x

n further things r not working. please provide the help.

What "further things"?

ill also give the list of gems installed.. *** LOCAL GEMS *** actionmailer (2.2.3) actionpack (2.2.3) activerecord (2.2.3) activerecord-odbc-adapter (2.0) activeresource (2.2.3) activesupport (3.0.5, 2.2.3) builder (3.0.0) dbi (0.4.3) deprecated (3.0.0) minitest (2.0.2, 1.6.0) rails (2.2.3) rake (0.8.7) rdoc (2.5.8) now guide me with best tutorial

Well, what tutorials have you followed to get you to this position? Have you looked at the Ruby on Rails "getting started" guide?

...and google for "Rails getting started" for dozens more links.

BTW You're asking about Netbeans 6.0, while the current release is 6.9... I'd suggest using the latest release, as it works well, but for the majority of things you need to use at your level (or arguably at any level... but let's not start that again! :slight_smile: any text editor would be fine. Don't rely on the IDE to do stuff for you (like creating projects, generating migrations, running rake takes); but when you know how to do it yourself, use the IDE if it makes it easier for you then.
