How do EJBs communicate between an Enterprise Application and an EJB Module?

Sun Java System Application Server Platform Edition 9.0_01 (build
b02-p01)
How do EJBs communicate between an Enterprise Application and an EJB
Module?
I'm going to assume that the standard Remote and Local rules apply, even
though one EJB is in a .ear and the other is in an EJB .jar?

I believe if it's outside the EAR you have to use Remote.

Yea, only elements deployed within the same EAR can enjoy Local semantics, outside of the EAR you have to use Remote.
Now, the fact than an EJB may be in a JAR that's deployed WITHIN an EAR, doesn't change that. The EJB in the JAR is deployed IN the EAR, so it can use Local calling even though it's packaged within a JAR.
For example, I have common EJBs in their own library JAR file that I use with different EARs, but they all enjoy Local calling semantics once deployed within an EAR.
