IIOP and Java EE

Is it true that Java EE objects don't use IIOP unless they are taking to software that wasn't written in Java?

Is it true that EJBs are built on RMI which uses TCP/IP sockets to communicate unless the other end is not java software in which case IIOP can be used?

Hi,

the vendor of an app server can choose the protocol for distributed
environments. The "simplified layer" is not tight to a specific protocol
as in the EJB2.1 Spec.
Currently, most vendors use JRMP when using the simplified layer (No classic Remote Interface, no direct Home Object).
When a native client is involved (C++ eg), the simplified layer cannot be
used. In this case, the EJB must be implemented as an EJB2.1 component (but more convenient now-annotations be still be used).

Hope this will help.
