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). |
