Anyone has a webrick server which works with a cgi test file, to share  
with me?  
Hopefully, not all webrick users are at the rails conference!

I have tried various combinations with various errors. Here is the  
latest attempt  
using the info on this page for server and test file  
[http://microjet.ath.cx/webrickguide/html/CGIHandler.html](http://microjet.ath.cx/webrickguide/html/CGIHandler.html)  
-----------------\>  
require ‘webrick’

include WEBrick # let’s import the namespace so  
# I don’t have to keep typing  
# WEBrick:: in this documentation.

def start\_webrick(config = {})

# always listen on port 8080

config.update(:Port =\> 8080)  
server = HTTPServer.new(config)  
yield server if block\_given?  
[‘INT’, ‘TERM’].each {|signal|  
trap(signal) {server.shutdown}  
}  
server.start

end

start\_webrick {|server|  
cgi\_dir = ‘/library/webserver/documents/ruby/cgi-bin’  
server.mount(‘/cgi-bin’, HTTPServlet::FileHandler, cgi\_dir,  
{:FancyIndexing=\>true})  
}

with the test file in cgi-bin, test2.cgi, executable  
#!/usr/bin/env ruby  
print “Content-type: text/plain\r\n\r\n”  
ENV.keys.sort.each{|k| puts “#{k} ==\> #{ENV[k]}”}

I get an error message.  
env: ruby: No such file or directory  
With other attempts I get other errors.

I started with the webserver on this page  
[http://microjet.ath.cx/webrickguide/html/What\_is\_WEBrick.html](http://microjet.ath.cx/webrickguide/html/What_is_WEBrick.html)  
----------------\>  
require ‘webrick’

include WEBrick # let’s import the namespace so  
# I don’t have to keep typing  
# WEBrick:: in this documentation.

def start\_webrick(config = {})

# always listen on port 8080

config.update(:Port =\> 8080)  
server = HTTPServer.new(config)  
yield server if block\_given?  
[‘INT’, ‘TERM’].each {|signal|  
trap(signal) {server.shutdown}  
}  
server.start

end

## start\_webrick(:DocumentRoot =\> ‘/library/webserver/documents/ruby/cgi-bin’)

it serves a hello.html file in cgi-bin directory fine.  
-----------------\>

 A Small Hello 
# Hi

This is very minimal "hello world" HTML document.

This particular error has nothing to do with webrick. What is happening  
is that the /usr/bin/env command cannot find ruby in it’s path. The  
first thing to try would be to replace

#!/usr/bin/env ruby

With

#!/usr/bin/ruby

Or where ever your ruby image is (try ‘which ruby’ to find out).

Thank you, changing that line did fix this example.  
And with this line my other test cgi script works too. Thank you!!!

start\_webrick(:DocumentRoot =\> ‘/var/www’)

is functionally similar to:

start\_webrick {|server|  
doc\_root = =’/var/www’  
server.mount("/" HTTPServlet::FileHandler doc\_root,  
{:FancyIndexing=\>true})  
}

What is a webrick servlet?  
[http://microjet.ath.cx/webrickguide/html/CGIHandler.html](http://microjet.ath.cx/webrickguide/html/CGIHandler.html)

I can serve my cgi test file with a webrick server with or without  
servermount…  
why does this page seem to say cgi needs a cgi handler?  
Are the two servers different?

first server  
---------------\>  
require ‘webrick’

include WEBrick # let’s import the namespace so  
# I don’t have to keep typing  
# WEBrick:: in this documentation.

def start\_webrick(config = {})

# always listen on port 8080

config.update(:Port =\> 8080)  
server = HTTPServer.new(config)  
yield server if block\_given?  
[‘INT’, ‘TERM’].each {|signal|  
trap(signal) {server.shutdown}  
}  
server.start

end

start\_webrick(:DocumentRoot =\>  
‘/library/webserver/documents/ruby/cgi-bin’)

second server  
------------------\>  
require ‘webrick’

include WEBrick # let’s import the namespace so  
# I don’t have to keep typing  
# WEBrick:: in this documentation.

def start\_webrick(config = {})

# always listen on port 8080

config.update(:Port =\> 8080)  
server = HTTPServer.new(config)  
yield server if block\_given?  
[‘INT’, ‘TERM’].each {|signal|  
trap(signal) {server.shutdown}  
}  
server.start

end

start\_webrick {|server|  
cgi\_dir = ‘/library/webserver/documents/ruby/cgi-bin’  
server.mount(‘/cgi-bin’, HTTPServlet::FileHandler, cgi\_dir,  
{:FancyIndexing=\>true})  
}
