| 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). |
