The usual response to this situation is to use dependency injection. You 
write objects without worrying too much about how they will get references 
to each other, then use some sort of container to wire them up. If you 
have a lot of singleton objects, as it sounds like you do, then you can 
use a fairly simple type- or annotation-driven injection system like Guice 
or CDI to inject dependencies.

I am uncertain whether this is actually better than having a God Object - 
sorry, application context - sitting in the middle of the system waving 
little static tentacles around, but it'll get you more brownie points.
