<p>
Java RMI over IIOP combines RMI technology with CORBA technology. Like plain RMI,
RMI over IIOP allows to work completely in the Java programming language 
(no IDL). When CORBA needs a separate helper class for each structure being
passed, RMI over IIOP only needs stubs and ties for the objects that are remotely
accessible. As a result, development with RMI-IIOP is easier. However the 
specialised pure CORBA helpers needs no reflection to transfer they structures 
and hence may be faster than methods, used by both RMI-IIOP and plain RMI.
</p><p>
Like RMI, RMI over IIOP provides flexibility by allowing to pass any serializable
Java object (Objects By Value) between application components. A certain
"imaginary IDL" is automatically supposed; this IDL can be explicitly generated
and later used to interoperate with non-java application.
</p><p>
Like CORBA, RMI over IIOP is based on open standards defined with the 
participation of hundredsof vendors and users in the OMG. It uses IIOP 
communication protocol that provides much better interoperability with other 
programming languages.
</p><p>
With RMI/IIOP you can use advanced CORBA features: multiple objects per servant
and servants per object, servant activators and locators, servant, client and
ior interceptors, CORBA naming service, various ORB policies, stringified object
references and so on. This functionality is based on CORBA value type standard.
RMI/IIOP supports (and GNU Classpath implements) transferring of the arbitrary 
connected object graphs (graph flattenning).
</p><p>
GNU Classpath RMI-IIOP functionality is implemented as described in
OMG formal/03-09-04 (IDL to Java mapping v1.3). Value types are written as 
described in formal/04-03-12 (CORBA 3.0.3).
