Java RMI over IIOP combines RMI technology with CORBA technology. Like plain RMI,
|
| 45 |
|
|
RMI over IIOP allows to work completely in the Java programming language
|
| 46 |
|
|
(no IDL). When CORBA needs a separate helper class for each structure being
|
| 47 |
|
|
passed, RMI over IIOP only needs stubs and ties for the objects that are remotely
|
| 48 |
|
|
accessible. As a result, development with RMI-IIOP is easier. However the
|
| 49 |
|
|
specialised pure CORBA helpers needs no reflection to transfer they structures
|
| 50 |
|
|
and hence may be faster than methods, used by both RMI-IIOP and plain RMI.
|
| 51 |
|
|
</p><p>
|
| 52 |
|
|
Like RMI, RMI over IIOP provides flexibility by allowing to pass any serializable
|
| 53 |
|
|
Java object (Objects By Value) between application components. A certain
|
| 54 |
|
|
"imaginary IDL" is automatically supposed; this IDL can be explicitly generated
|
| 55 |
|
|
and later used to interoperate with non-java application.
|
| 56 |
|
|
</p><p>
|
| 57 |
|
|
Like CORBA, RMI over IIOP is based on open standards defined with the
|
| 58 |
|
|
participation of hundredsof vendors and users in the OMG. It uses IIOP
|
| 59 |
|
|
communication protocol that provides much better interoperability with other
|
| 60 |
|
|
programming languages.
|
| 61 |
|
|
</p><p>
|
| 62 |
|
|
With RMI/IIOP you can use advanced CORBA features: multiple objects per servant
|
| 63 |
|
|
and servants per object, servant activators and locators, servant, client and
|
| 64 |
|
|
ior interceptors, CORBA naming service, various ORB policies, stringified object
|
| 65 |
|
|
references and so on. This functionality is based on CORBA value type standard.
|
| 66 |
|
|
RMI/IIOP supports (and GNU Classpath implements) transferring of the arbitrary
|
| 67 |
|
|
connected object graphs (graph flattenning).
|
| 68 |
|
|
</p><p>
|
| 69 |
|
|
GNU Classpath RMI-IIOP functionality is implemented as described in
|
| 70 |
|
|
OMG formal/03-09-04 (IDL to Java mapping v1.3). Value types are written as
|
| 71 |
|
|
described in formal/04-03-12 (CORBA 3.0.3).
