Ruby

Hi all,

I am a newbie to servlet programming using webrick…
Was wondering how to accept data from a form and do necessary
processing…
To start with i wrote a sample servlet that accepts a name and prints
“welcome ”

But I do not know how to take this value from the form into the servlet
and print it out…
this is what i worte… can anyone please help me with this.

s = HTTPServer.new( :Port => 9000)
class TextServlet < HTTPServlet::AbstractServlet
def do_GET(req, res)
res.body = %Q{

Name:


}
res[‘Content-Type’] = “text/html”
end
end

class Dataread < HTTPServlet::AbstractServlet
def do_GET(req,res)
res.body = %Q{

Welcome

}
res[‘Content-Type’] = ‘text/html’
end
end

trap(“INT”) {s.shutdown}
s.mount(“/” , TextServlet)
s.mount(“/text.rb”, Dataread)
s.start

I am a total beginner to this , so please help me out…
Also if there is any resource online available do point me to it, apart
from webrick.org

Hi Wrapster,

Forvive the late reply, but I only just joined up :wink:
You could replace the text between your <>'s to #{req.query[‘text1’]}
