HI all,  
I have 3 files.In pubsubserver.rb, I wrote the classes(according to  
RCR198). In Publisher.rb, i have created an object of main class and  
bound it to the server

server=Abc.new()  
Drb.start\_service(‘druby://:localhost:9000’,server)  
Drb.thread.join

and in another file client.rb, i am using this server object and  
subscribing…but it is not working…it is working in non distributed  
fashion…Can anybody guide?

What do you mean by “it is not working”?
