I am not very familiar with the CORBA Object by Value (OBV) specification,
but sending classes by value is to my knowledge only possible in
restricted circumstances. The problem is that the other side needs to
understand the code that was sent. What should your SPARC do with a x86
executable or your Java client with a Python script?


omniORB as an ORB with a C++ binding does not support this.


There are rumours that some Java ORB supports classes as OBV, but only
among processes using the same ORB (and language binding, obviously).
