Pub/Sub in Distributed setup


#1

Hi,
I want to implement RCR 198 in distributed environment.I wrote
subscriber as
follows

require ‘drb’
DRb.start_service()
a = DRbObject.new(nil,‘druby://localhost:9000’)
a.subscribe(:prof2 ) do |proxy|
proxy.method1 #this is a private method accessed thru proxy
end

But it is giving me unknown method error…please help

thanks

Where’s the other half of your code? What does the object that you
are connecting to look like?


#3

class Abc < Object
def method1
puts “in Method 1”
end
def method2
puts “in method 2”
end
publish :prof, :method1
publish :prof2, :method2
end

where Object is implemented as in RCR198.
and I bounded object to drb as

require ‘drb’
require ‘PubSubServer’
server = Abc.new
DRb.start_service(‘druby://localhost:9000’, server)
DRb.thread.join

Now, the client(code given below) is not able to fiqure out what proxy
is.How can i resolve this?

thanks

Could this just be a typo in your code?

a is subscribing to prof2 but then tries to call method1 (which is
published under prof)
