There is not ruby 2.0.2, you mean Rails 2.0.2. What version of Ruby are you using. What os? What plugins? Most people use the new mongrel for development, it comes up automatically. Do you have a reason for using Webbrick? If it is coming up automatically without you specifying it then there may be a bug in your configuration.

I use Rails 2.02 ruby 1.86 with netbeans on windows vista business and netbeans uses webbrick automaticly. Paul

I don't have Vista or netbeans so I cannot try to reproduce. Best of luck. Would it be hard for you to try running script/server from the command line and seeing what comes up and how it works, or would netbeans interfere with that? I have no idea.

Netbeans won't interfere. and I have the same error message

The stack trace gives you lots of useful information. The first line tells you where to look:

C:/ruby/lib/ruby/gems/1.8/gems/activerecord-2.0.2/lib/active_record/ vendor/mysql.rb:111:in `initialize'

Go to line 111 in that file, and you'll see:

      sock = TCPSocket::new(host, port>>ENV["MYSQL_TCP_PORT"]||(Socket::getservbyname("mysql","tcp") rescue MYSQL_PORT))

Looks like you're not connecting to your mysql server.

You’d usually get this error if your mysql server was down. Can you show us your database.yml file? We don’t need to see your password, just the adapter, host and socket will do.

I use Rails 2.0.2 and ruby 1.8.6 with netbeans on windows vista business and netbeans uses webbrick automatically.

NetBeans uses Rails' defaults, which is to use Mongrel if it's available, and otherwise Webrick. Thus, if you've gem intalled mongrel, NetBeans should be using it.
