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?

</div>

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)
