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](http://webrick.org)

Hi Wrapster,

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

Cheers,

Brad
