Hai  
I am trying to do DRB program  
but the server program throws an error like  
“Error:TestServer.rb:10: uninitialized constant Drb (NameError)”

These are my program

require ‘drb’  
class TestServer  
def doit  
“Hello,Distributed World”  
end  
end

a=TestServer.new  
DRb.start\_service(‘druby://localhost:3000’,a)  
Drb.thread.join

* * *

require ‘drb’  
DRb.start\_service()  
obj=DRbObject.new(nil,‘druby://localhost:3000’)

p obj.doit

* * *

I dont know what is going wrong ,will anybody tell me the solution?

Ok

It’s just a typo (and probably one many of us have made).
