I am a beginner so please excuse me, if i am doing something totally  
wrong.

I have created a class and here is what it looks like:

class ServiceSoap \< :🧼:RPC::Driver  
DefaultEndpointUrl =  
“[http://balrog/services/SearchWorker/service.asmx](http://balrog/services/SearchWorker/service.asmx)”  
MappingRegistry = :🧼:Mapping::Registry.new  
…  
…  
def initialize(endpoint\_url = nil)  
endpoint\_url ||= DefaultEndpointUrl  
super(endpoint\_url, nil)  
self.mapping\_registry = MappingRegistry  
init\_methods  
end  
…  
…  
end

I put in in app/controllers folder as “defaultDriver.rb”

in another controller, I am doing

require ‘defaultDriver.rb’

class RmssearchController \< ApplicationController  
layout “standard-layout”

```
def view
  obj = ServiceSoap.new(nil) # line 10
  response = ServiceSoap.helloWorld(nil)
  render :text => response
end

```

end

and I am getting “uninitialized constant ServiceSoap” error at line 10

Any help is appreciated. Thnaks in Advanve.

Btw, If I use irb in that directory, it works fine.

You don’t need to pass “nil” to the ServiceSoap constructor, try just  
ServiceSoap.new
