|
What is PolyORB?
|
|
----------------
|
|
|
|
PolyORB is a polymorphic, reusable infrastructure for building
|
|
object-oriented distributed systems. Middleware environments are
|
|
software libraries that hide the complex issues of distribution and
|
|
provide the programmer with high-level abstractions that allow easy
|
|
and transparent construction of distributed applications. A number
|
|
of different standards exist for creating object-oriented distributed
|
|
applications. These standards define two things:
|
|
|
|
* the interface seen by the developer's applicative objects;
|
|
* the protocol used by the middleware environment to talk to other
|
|
nodes in the distributed application.
|
|
|
|
Usually, middleware for one platform supports only one set of such interfaces,
|
|
and cannot interoperate with other platforms.
|
|
|
|
A polymorphic middleware allows the existence of several different
|
|
implementations of each of these aspects to be used within the same
|
|
middleware framework. In addition, PolyORB allows such different
|
|
personalities to coexist in the same instance of the running middleware;
|
|
it decouples the personality presented to applications on one side
|
|
("application personality"), and the personality presented to other
|
|
middleware on the other side ("protocol personality"). Multiple
|
|
implementations of each personalisable aspect can coexist within the same
|
|
instance of the running middleware: unlike previous generic middleware,
|
|
PolyORB is actually schizophrenic.
|
|
|
|
The decoupling of application and protocol personalities, and the
|
|
support for multiple simultaneous personalities within the same running
|
|
middleware are key features required for the construction of interoperable
|
|
distributed applications. This allows PolyORB to communicate with
|
|
middleware that implement different distribution standards: PolyORB
|
|
provides middleware-to-middleware interoperability.
|
|
|
|
The PolyORB architecture also permits the automatic,
|
|
just-in-time creation of proxies between incompatible environments
|
|
(although this feature is not implemented yet).
|
|
|
|
PolyORB can be used in Ada 95 and Ada 2005 applications alike. It is
|
|
implemented in Ada 2005 and C.

Bug reports
|
|
-----------
|
|
|
|
If you find a bug or would like to submit patches, please do so indicating
|
|
the release you use. We accept patch files. To produce such a patch file,
|
|
put your files in the PolyORB directory and our files in the directory
|
|
PolyORB.orig, and use the following command:
|
|
|
|
diff --recursive --context PolyORB.orig PolyORB > patch_file
|
|
|
|
If your diff version do not understand the --recursive or --context
|
|
option, please use the GNU diffutils package which may be found on any
|
|
GNU archive (e.g. ftp://ftp.lip6.fr/pub/gnu/).
|
|
|
|
Note that unified diff files (-u option of GNU diff) are also welcomed.
|
|
|
|
Unsupported users may directly send their patches and bug report via
|
|
e-mail at the address
|
|
polyorb-bugs@lists.adacore.com
|
|
|
|
or seek community support through the public mailing list:
|
|
polyorb-users@lists.adacore.com
|
|
|
|
Please use the Problem Report Form in docs/PROBLEM-REPORT-FORM.
