[fw-general] Best way to utilize Zend_Registry

[Brian Dittmer]

Hey guys, I'm fairly new to the Zend Framework and have a few 
questions.  Firstly let me begin by describing the architecture I have 
in place.

I have a set of domain classes, each of which represent a specific table 
in the database.  I'm using a set of service classes I built to populate 
the domain objects.  Pretty standard stuff.  These service and domain 
classes all reside in their own specific lib directory so they can be 
used across our admin, intranet and public facing websites. 

My question is can I utilize the Zend_Registry to provide a single 
instance of each of my Service classes across each app domain (public, 
intranet, admin)?  If so how would I go about initially populating the 
registry?  I come from the Java world and there I'd typically be using 
the Spring framework to inject dependencies into and maintain my service 
classes.  All of that would typically occur on startup of the servlet 
container.  I'll be using a similiar technique to maintain an instance 
of Zend_Config and a few other special classes I have developed.  Any 
help with this would be much appreciated!
