Hello Sheila,
                       Thank you for the reply. I am still wondering how 
do I bind a particular I/P/O/E to a service if the domain is not 
specified. Since congoOrderShippedEffect is a part of ExpressCongo, 
don't we have to bind these somewhere. At what stage should this be 
happening?

peace,
mithun
