Subject: windows and http servers on ruby

Hi,
I wrote custom webrick servlet which parses *.html files with embedded
ruby code. It works fine on Linux, but on Windows it doesn't work properly
because pictures that are supposed to be on a web page do not show.

What can I do?

#!/usr/bin/ruby
require 'webrick'
include WEBrick

class CustomServlet < HTTPServlet::AbstractServlet
	def do_GET(req, resp)
	unless defined?(ERB)
		@logger.warn "#{self.class}: ERB not defined."
		raise HTTPStatus::Forbidden, "ERBHandler cannot work."
	end
	#puts req.inspect
	#puts "++++ #{req.request_uri} +++++++++++++++"
	str=req.inspect
	path=Dir.pwd+req.path
	uri=req.request_uri.to_s
	if File.stat(path).directory?
		resp.body << "\n<html><head><title>Directory</title></head><body>\n"
		resp.body << "<h2>Directory: #{req.path}</h2>"
		entries=Dir.entries(path)
		resp.body << '<a href="/">Root directory</a>'+"<br>\n"
		entries[1..-1].each {|x| 
			resp.body << '<a href="' << uri
			resp.body << '/' if req.path[-1,1] != '/'
			resp.body << x << '">'
			x='Parent Directory' if x=='..'
			resp.body << x << "</a><br>\n" 
		}
		resp.body << "\n</body></html>"
	else
        #puts 'going to process file '+path
        file=File.open(path).read #load normal file
        if (path[-5..-1]=='.html' or path[-4..-1]=='.htm')
			rhtml=ERB.new(file) #convert served string into code
			#rhtml.run #run the code
			file=rhtml.result #copy result to another string
			resp.body << file
		else
			resp.body << file
		end #if 
	end #if
	
  end#def
end#class



def start_webrick(config = {})
  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| 
server.mount('/',CustomServlet,"#{Dir.pwd}/proba")
}
