This package provides the support of <a href="http://www.CORBA.org">CORBA</a>;
|
|
see <a href="#overview">overview</a> of the implemented functionality.
|
|
<p>
|
|
CORBA a system that applications use to work over networks. CORBA messages
|
|
are binary, not text oriented. They practically cary no "data wrapping"
|
|
information like XML <opening> </closing> tags. Hence CORBA
|
|
objects easier exchange large amounts of binary data. CORBA can work
|
|
in such data-intensive application areas as telecommunications or radio
|
|
broadcasting. Java programs connect to CORBA objects without care
|
|
about what platform they run on, where they exist in the network, or what
|
|
language they were written in. The remote CORBA objects appear to the
|
|
programmer as the ordinary Java objects and can be passed as
|
|
parameters in both remote or local method invocations.
|
|
</p><p>
|
|
The CORBA processing unit is divided into {@link org.omg.CORBA.Object}
|
|
that is exposed to the client and the servant
|
|
({@link org.omg.PortableServer.Servant} where the method, invoked on
|
|
object, is finally delegated. It can be multiple objects per servant or
|
|
multiple servants per object. The servant for particular object or
|
|
even particular call can be dynamically chosen at run time using
|
|
{@link org.omg.PortableServer.ServantManager}.
|
|
</p><p>
|
|
All stages of both local and remote invocations on CORBA objects can be
|
|
monitored and modified using {@link org.omg.PortableInterceptor.Interceptor}.
|
|
The interceptors can add an extra data to the CORBA message (these data
|
|
can be later accessed by other interceptor on remote side).

<h4>Overview of the currently implemented CORBA functionality</h4>
|
|
The CORBA implementation in the Classpath project is now a working
|
|
prototype.
|
|
<ul>
|
|
<li>This prototype is interoperable with Sun's implementation v 1.4,
|
|
transferring object references, primitive types, narrow and wide strings,
|
|
arrays, structures and trees between these two platforms.
|
|
</li>
|
|
<li>The prototype provides interoperable support for the Abstract interface
|
|
and Value types. Those appear in 1.3, being a feature of CORBA 2.3.
|
|
</li>
|
|
<li>The remote exceptions are also transferred and handled as expected.
|
|
</li>
|
|
<li>The support for parsing stringified object references (IORs), both
|
|
Big and Little Endian encoded, is implemented.
|
|
</li>
|
|
<li>The redirection commands works, LOCATION_FORWARD_PERM changing the
|
|
target address until the application is restarted and LOCATION_FORWARD
|
|
redirecting for the current session only.
|
|
</li>
|
|
<li>Both Little and Big Endian encoded messages are accepted. The encoding
|
|
of the sent messages is the same as used in the stringified IOR reference
|
|
of that object or Big Endian, if no such data available.
|
|
</li>
|
|
<li>You can use both request-oriented (based on {@link org.omg.CORBA.Request}
|
|
and stream-oriented (based on {@link org.omg.CORBA.portable.ObjectImpl}
|
|
invocation models. The current release includes the working examples,
|
|
demonstrating the client-server communication using both methods.
|
|
</li>
|
|
<li>These examples also show, how to use the Classpath naming service.
|
|
</li>
|
|
<li>The IDL compiler is not yet written (and not even started), but as a
|
|
side effect of the required compatibility, the implementation seems
|
|
accepting the output of the Sun's idlj.
|
|
</li>
|
|
<li>The Portable Object Adapter is already released. For details on POA,
|
|
see the {@link org.omg.PortableServer} package.</li>
|
|
<li>We provide the implementation of the {@link org.omg.DynamicAny}
|
|
package. ORB returns the working DynAnyFactory that produces working
|
|
DynAny's as defined in OMG specification.</li>
|
|
<li>The Portable Interceptor is also complete. See
|
|
{@link org.omg.PortableInterceptor} package for details how to register
|
|
and use CORBA interceptors.
|
|
<li>All GNU Classpath classes in omg.org namespace are newly written using
|
|
the OMG .pdf document (Version 3.0.3, formal/04-03-12).
|
|
</li>

</ul>
