hi  
first off all a happy new year to you all.  
I’m using netbeans 6 and ruby 2.02.  
at this point I get my index page in my view in this format  
index.html.erb and not like before index.rhtml  
when I enter localhost:3000/lijsten/index I get the following error  
message

Errno::EBADF in LijstenController#index

Bad file descriptor - connect(2)

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.

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.

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.

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.

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.
